General Basic C280 Diesel Engine Design
The C280 Engine Family for marine applications is a modern, highly efficient, IMO certified engine series consisting of in-line engines of 6 and 8 cylinders and vee engines of 12 and 16 cylinders. These are four stroke, non-reversible engines rated at speeds from 900 to 1000 rpm and intended for use as main propulsion and electric power generator drivers for marine applications. The engines are turbocharged, charge air cooled and with a direct injection fuel system using unit fuel injectors. The use of individual fuel injectors eliminates the need for high pressure piping and provides for an accurate, high injection pressure. The engine block is a nodular cast iron block. The intake plenum runs the full length of the engine, providing even air distribution to the cylinders. The crankshaft is a pressed forging that is induction hardened. A counter-weight for each cylinder is bolted to the crankshaft using a robust 3 bolt design. Crankshaft end flanges are identical so full power can be taken off from either end. The main, rod and camshaft bearings are steel-backed, nickel bonded aluminum with a lead-tin overlay, copper-bonded to the aluminum. Experience has shown this produces the best bearing construction available for the longest possible life. The connecting rods are forged, heat treated and shot peened before machining. The special four-bolt design allows for an extra-large bearing which reduces bearing load and extends bearing life. The cylinder liners are high alloy iron castings, induction hardened, plateau honed and water jacketed over their full length. The liners are equipped with an antipolishing ring (cuff) to avoid piston / liner carbonizing and thus improve lube oil control and liner life. The pistons are two-piece with a steel crown and forged aluminum skirt for excellent strength and durability, yet light weight. Each piston has four rings, two in hardened grooves in the crown and two in the skirt. The top compression ring is asymmetrically faced with a chrome-ceramic matrix coating to provide extended ring and liner life. The two middle rings are taper-faced and chrome plated, while the lower lube oil control ring is double rail chrome faced, with a spring expander. Oil is jet sprayed into passageways within the pistons for cooling and lubrication of the piston pin. The valve seats on the replaceable inserts are induction-hardened. Positive rotators on all the valves maintain a uniform temperature and wear pattern across the valve face and seat. The exhaust and air inlet valves are both manufactured from Nimonic 80A material.

GENERAL
The cooling system can either be combined circuit or separate circuit, depending on emissions levels and available sea water temperature. Both versions use two identical centrifugal pumps to get coolant (usually a 50/50 water/glycol mix) to the aftercooler, oil cooler, block, and heads. Orifices are used to ensure correct coolant

C280 MARINE PROJECT GUIDE flow to each component. There is an optional connection for a jacket water heater if required to meet cold-starting applications. The air starting system is highly reliable turbine driven air motor that does not contain rubbing parts and does not required external lubrication. The engine mounting system is a robust system of mounting feet that enable proper support to the installation foundation and top plate(s). The C280-6 and C280-8 are designed with four mounting feet and the C280-12 and C280-16 use six mounting feet.

Ratings meet the classification society maximum requirements of 45°C (113°F) to the air inlet of the turbocharger and 32°C (100°F) sea water temperature without derate, unless otherwise stated.
Matching of Propellers and Waterjets
GENERAL
Controllable Pitch (CP) propellers are normally designed so that 90 to 100% of the rated power is utilized when the ship is on trial at a specified speed and load. Overload protection or load control is necessary to protect the engine from overload in the event of heavy vessel loading weather conditions, sea state, or hull fouling.
4
Waterjets approximate a fixed pitch propeller demand curve and can also be affected by vessel loading, weather conditions, sea state, and hull fouling. The waterjet power demand should be matched such that these conditions do not result in engine overload. The waterjet to engine match should be based on expected heavy ship conditions, propulsion system power losses, reduction gear losses, etc. The following graph provides an example of a correct waterjet match.

Correct Waterjet Match
System Response The waterjet should be matched to the engine such that the engine can smoothly reach its rated speed in a time frame that optimizes acceleration and fuel combustion (smoke). This optimized condition is frequently programmed into the electronic governing system and the waterjet should not inhibit the programmed acceleration rate. An oversized waterjet may result in engine lug (maximum fuel @ less than rated rpm), resulting in owner dissatisfaction with vessel performance, as well as possible harm to the engine from excessive exhaust temperatures.

GENERAL
Engine and Waterjet Tolerances Engine and waterjet tolerances should be taken into account in the propulsion system design. Waterjets typically have a rated speed tolerance of +/- 0.5% to +/- 1.5%. Thus the waterjets will absorb the rated power somewhere within this speed band tolerance. If the situation arises where the waterjet is supplied within
5
C280 MARINE PROJECT GUIDE these specifications, but at the lower limit of the speed tolerance, it could mean that the propeller demand would require 4.5% more power at the nominal rated speed. If the waterjet is supplied with the ability to absorb the power only at the upper limit of the speed tolerance, the engine may not be able to pull the rated power out of the waterjet, as the engine may not be able to operate at this higher rpm. The C280 tolerances provide nominal power +/- 1.5% with a rated speed tolerance of + 0.5% to – 1.0%. To insure the best possible match between the engine and the waterjet in view of the tolerance differences, the following procedure applies. Engine adjustment and acceptability guidelines for sea trials: 1. If the maximum engine speed in the ship installation during full load sea trials is between 995 rpm and 1000 rpm, no adjustments will be made to the engine settings. 2. If the maximum engine speed in the ship installation during full load sea trials is 1000 rpm and the shipyard measured parameters such as boost, fuel rate, rack position and/or cylinder pressure indicate that between 1001 and 1005 rpm is necessary to achieve the rated power, no adjustments will be made to the engine settings. 3. If the maximum engine speed in the ship installation during full load sea trials is between 990 rpm and 994 rpm and the shipyard parameters indicate that the engine is in the lower end of the power tolerance, the rack setting can be increased so that the minimum power will be within -1.5% tolerance (2670 bkW in the case of the 2710 bkW rating) based on standard ambient conditions. A new specification will be created to reflect the new rack setting and a new engine nameplate will be stamped. 4. If the maximum engine speed in the ship installation during full load sea trials is 1000 rpm and the shipyard measured parameters indicate that between 1006 rpm and 1010 rpm is necessary to achieve the rated power, the engine rated speed may be increased. The engine rated speed will not exceed 1010 rpm and Caterpillar reserves the option of reducing fuel stop setting to provide a maximum output of 2750 bkW at standard conditions within the 1006-1010 rpm speed range. If necessary, a new specification will be created to reflect the new rack setting and a new nameplate will be stamped. 5. A maximum attainable engine speed of less than 990 rpm is considered unacceptable for lug for continuous operation. Requirements / Conditions: 1. The dynamometer test results at fuel stop power will be used as the criteria for evaluating installed engine power. GENERAL
2. ISO standard reference conditions apply for power, not site conditions.
6
3. Minimum power setting (no negative tolerance in the dyno) will be driven by the quoter including the associated additional cost. 4. The minimum tolerance on engine power in the dyno will be reduced to 2%. ©2010 Caterpillar® All rights reserved.
5. A tolerance of +/- 1.5% applies to engine power in the field based on standard conditions. 6. The standard rated power and speed will not be changed on the new nameplate, only the rack setting. Note: The nominal propeller demand curve shown in the C280-8 Power and Speed Tolerances Graph shows the cubic demand curve through the engine design point of 2710 bkW at 1000 rpm. The propeller demand curves 2 and 3 are matched through the minimum and maximum power tolerance limits at rated speed. C280-8 Power and Speed Tolerances
Waterjet Tolerances Standard waterjet tolerances are +/- 1.5% speed at rated power. This speed tolerance is a function of the pump design, hull form, vessel speed and waterjet intake design. The engine speed tolerance at rated power is less than the waterjet tolerance (+0.5%/-1.0% versus +/- 1.5%). This means there is a possibility for the waterjet to be oversized or undersized if the maximum minus or plus speed tolerance on the water jet is obtained at rated power.
©2010 Caterpillar® All rights reserved.
GENERAL
An oversized waterjet will cause the engine to operate at fuel stop rack (lug) when the engine is set for the rated 2710 bkW at 1000 rpm. The engine speed may be less than the minimum 990 rpm (-1.0% engine speed tolerance) required to obtain power within the minus tolerance band with factory rack setting. The engine can operate in lug continuously down to 980 rpm. However, the engine power output will be out of the minus tolerance band.
7
C280 MARINE PROJECT GUIDE An undersized waterjet will prevent the engine from reaching rated power at the rated 1000 rpm. Engine speed may be increased to a maximum of 1015 rpm but power output may still be below the minimum tolerance of 2670 bkW with the factory rack setting. The rack setting may be changed to achieve a maximum output of 2750 bkW at standard ambient conditions at 1015 rpm.
GENERAL
To minimize the possibility of a significantly oversized waterjet, the customer and/or jet manufacturer may choose to use a different nominal jet sizing point than the rated engine operating point (2710 bkW at 1000 rpm). By choosing a lower nominal water jet rating at 1000 rpm, the jet speed tolerance band may be made to fall entirely within the engine limits such that continuous lug operation is not possible.

Lubrication Oil System General
The lube system is designed to provide a constant supply of filtered oil at 430 kPa pressure under all engine operating conditions. The major feature of the C280 lube system is the priority valve, shown in Figure 1, to regulate the oil pressure at the cylinder block main oil gallery rather than at the oil pump. The oil gallery pressure thus becomes independent of the oil filter and oil cooler pressure drops. Priority Valve
Figure 1
Internal Lubrication System
Thermostats Four thermostats in the lube system control the oil inlet temperature to 85°C. Oil Filters The oil pan is equipped with a 650-micron suction screen. The duplex final 20micron lube oil filters can be changed while the engine is operating. The normal procedure specifies the filters to be changed at 100 kPa pressure drop across the filters. ©2010 Caterpillar® All rights reserved.
LUBRICATION OIL SYSTEM
Oil Coolers The engines are equipped with an engine mounted two element lube oil cooler, with the water flow arranged in series. A three element lube oil cooler is available on vee engines to ensure proper cooling in high ambient conditions. These oil coolers are in a shell and tube type design.
61
C280 MARINE PROJECT GUIDE Centrifugal Bypass Filters Engine mounted centrifugal bypass oil filters are installed as standard. The filters receive 3-4% of the oil pump flow and remove solid, micron size particles and can extend the oil filter change periods. The centrifugal filters each have a dirt capacity of 3.6 kg (8 lb.). Typical cleaning intervals are outlined in the Maintenance Interval Schedule section of this guide and discussed in detail in the Caterpillar Operation and Maintenance Manual. An additional shipped loose lube oil centrifuge, customer mounted off-package, can be provided to circulate the oil sump in order to extend the oil life. Oil Pumps The engine driven oil pumps provide more than the required engine oil flow at rated conditions. This allows high oil pressure early in the operating speed range and provides flow margin. Lube Oil Heaters The Caterpillar lube oil heating system is a package mounted unit that is used in combination with a jacket water heater. The typical package includes: •
Circulating pump
•
Electric oil heater (9 kW for In-line engines and 11 kW for Vee engines)
•
Control panel, including pump control and temperature control, etc.
Lube oil heaters may be necessary when ambient temperatures are below 10°C (50°F) or when quick start capability is required. In some applications, jacket water heaters in conjunction with continuous prelubrication may satisfy lube oil heating requirements; however, this method of heating should be carefully considered before ordering.
Prelubrication
LUBRICATION OIL SYSTEM
Prelubrication is required for C280 series engines and several types of automatic prelubrication systems are available from Caterpillar. These automatic prelubrication systems include starting controls, electric or air powered pumps, a check valve and engine piping. The prelube pumps, whether electric or air powered, must be powered from a source independent of any single failure that could prohibit the engine from starting. A check valve is used to prevent pressurized oil from flowing through the prelube pump during engine operation.
62
Automatic prelubrication systems available for Caterpillar C280 diesel engines are: •
Redundant Prelube System (recommended system)
•
Intermittent Prelube System
•
Continuous Prelube System
Redundant Prelube System (recommended system) The redundant prelube system combines electric continuous and pneumatic intermittent prelube systems, offering the benefits of both. Under normal circumstances, the electric continuous prelube pump keeps the engine ready for immediate start-up, but if the electric continuous pump should fail, the pneumatic ©2010 Caterpillar® All rights reserved.
intermittent prelube pump will operate. This system is typically selected for dynamic positioning rig applications (DP2 and DP3), when it is critical that an engine is able to start. Intermittent Prelube System The pneumatic intermittent prelube system uses an engine mounted pump that is engaged immediately prior to engine start-up, providing suitable performance for applications not requiring quick start capability. Continuous Prelube System The electric continuous prelube system eliminates the delay of waiting for the completion of the intermittent prelube cycle. This system is for immediate starting applications and is typically used in conjunction with jacket water and lube oil heating systems. Postlubrication C280 diesel engines have a standard postlubrication cycle of 60 seconds that maintains the oil flow after engine shutdown to protect the turbocharger bearings. However, an engine will not postlube if the Emergency Stop (E-Stop) button is depressed to shutdown the engine. Since an oil leak could potentially require the use of the E-Stop button, the postlube is disabled to stop the flow to a possible leak. Since no postlube occurs with the use of the E-Stop button, it should be used for emergency shutdowns only.
Generator Bearing Lube Oil System
The large generators packaged with C280 Series Generator Set packages will typically require a forced bearing lubrication system, which typically utilizes a mechanical generator-driven pump to supply lubrication to both front and rear generator bearings. Caterpillar supplies a Generator Lubrication Module (GLM) for Kato Generators to provide for prelubrication of the generator bearings prior to start-up and to operate in the event of the mechanical pump failure. The GLM is a prepackaged unit that is typically base mounted, but can be remote mounted to suit site specific application requirements. The typical GLM package includes: Oil tank

Oil Requirements
Due to significant variations in the quality and performance of commercially available lubrication oils, Caterpillar recommends the oils listed in the following table for C280 Series Engines that use distillate diesel fuel.

Lubricant Viscosity The primary recommendation for the C280 family of engines is SAE 40-grade oil. SAE 30 and some multigrade oils may be used if the application requires. SAE 30 is preferable to multigrade oil.
LUBRICATION OIL SYSTEM
Total Base Number (TBN) C280 engines operating on distillate fuel require a TBN of 10 times the sulfur level measured in percent of weight. (Example: For a sulfur content of 1% weight, the TBN would be 10.) The minimum TBN level regardless of the sulfur content is 5. Excessively high TBN or high ash oils should not be used in C280 Series engines on distillate fuel, as these oils may lead to excessive piston deposits and loss of oil control. Successful operation of C280 series engines has generally been obtained with new TBN levels between 10 and 15.
64
Use of Commercial Oil Caterpillar does not recommend the names of other commercial brands of lube oils, but has established guidelines for their use. Commercially available lubrication oils may be used in Caterpillar C280 Series Diesel Engines, but they must have proof of performance in Caterpillar’s Field Performance Evaluation, included in Caterpillar document SEBU7003, 3600 Series and C280 Series Diesel Engine Fluids Recommendations.
Oil Change Interval
To achieve maximum life from the engine oil and provide optimum protection for the internal engine components, a Scheduled Oil Sampling program (S•O•S) should be used. This program is available through the Caterpillar dealer network. If an ©2010 Caterpillar® All rights reserved.
S•O•S analysis program is not available, the oil change interval is recommended in accordance with the following table. Oil Change Intervals for C280 Series Diesel Engines Operating on Distillate Diesel Fuel Engine Model Lube Oil Capacity Oil Change Interval C280-6 C280-8 C280-12 C280-16

Service Service Service Service
Hours Hours Hours Hours
Scheduled Oil Sampling TBN, viscosity and oil consumption trends must be analyzed every 250 hours. The S•O•S analysis involves a two-part test program: A) Wear Analysis The Wear Analysis identifies engine wear elements present in the oil. These elements indicate the condition of the engine. B) Oil Condition Analysis. The Oil Condition Analysis identifies the wear status of the oil. The program will determine oil change intervals based on trend analysis and condemning limits established for the engine. Increasing Oil Change Intervals Oil change intervals can only be increased when the S•O•S analysis indicates that the condemning limits have not been reached, and only when trend lines indicate a stable constant slope. Oil change intervals should only be increased in 250-hour increments, especially in situations where the turn-around time for the oil analysis is long.
Change Interval without Oil Analysis Results If S•O•S analysis results are not available, the initial oil change interval should be used to determine oil change intervals. Even though oil sampling results may not be available on the recommended 250 hour intervals, oil samples should be analyzed at every oil change period, even if the turnaround time for the data is long.
Inclination Capability
The standard marine propulsion engine oil pan is capable of meeting the inclination criteria for installation angles (rear down), of 5° for the C280-6/C28012 engines and 3° for the C280-8/C280-16 engines. ©2010 Caterpillar® All rights reserved.
LUBRICATION OIL SYSTEM
Initial Oil Change Interval The following table shows the required initial oil change volume based upon engine type used and the standard oil sump size; typically an integral dry sump, built into base. Contact Caterpillar for non-standard oil sump initial change intervals.
65
C280 MARINE PROJECT GUIDE For marine auxiliary engine applications, the Caterpillar packages utilize a shallow dry sump mounted on the engine, which gravity drains into a wet sump that is integral to the base assembly. This design allows for a reduced engine room footprint, eliminates the need for a second lube oil pump and provides 15° static and 25° dynamic tilt capability. For generators supplied by others, generator manufacturer is responsible for providing any forced lubrication system that may be required for their generator to meet tilt requirements. For higher tilt requirements contact the factory.

C280 MARINE PROJECT GUIDE
Crankcase Ventilation System Crankcase Emissions
Crankcase emissions result from combustion byproducts and/or exhaust fumes escaping around the piston rings and into the crankcase, commonly called blow-by. If not controlled, this blow-by can contaminate the lube oil and pressurize the crankcase, possibly leading to an oil leak. Venting the emissions to the atmosphere is a simple solution to release the pressure and trapped fumes. Managing the emissions, however, adds complexity to crankcase ventilation systems. Vent tubes and crankcase breathers are currently provided on the C280 diesel engine and integral oil sump to allow this gas to escape. However, as emission laws become more stringent, it is inevitable that crankcase emissions will be included in total system emission values. In the future, ventilating crankcase emissions to the atmosphere will be discouraged or prohibited. Current C280 diesel engines still require that crankcase fumes be vented to atmosphere. A closed-loop, on-engine crankcase filtration system (ingestive system) for the C280 series diesel engine is currently not available. Contact the factory for more details.
Crankcase Fumes Disposal
Do not vent crankcase and integral oil sump fumes into the engine room. The oily fumes will have a tendency to clog air filters.
CRANKCASE VENTILATION SYSTEM
Crankcase fumes should be discharged directly to the atmosphere through a venting system individual for each engine.
68
The engine has breathers located on each cylinder bank on the engine. Crankcase fumes vent pipes must be of sufficient size to prevent the buildup of excessive backpressure in the crankcase. Blow-by on a new engine will be approximately 0.02 m³/hr-bkW (0.5 ft³/hr bhp). The pipes should also be adequately sized to accommodate a worn engine. Size the vent piping for 0.04 m³/hr-bkW (1.0 ft³/hr bhp) with a maximum of 13 mm H2O (0.5 in. H2O) pressure drop in the piping. Formulas for calculating backpressure can be found in the Crankcase Ventilation section of the current Application and Installation Guide. Loops or low points in a crankcase vent pipe must be avoided to prevent liquid locks from the condensation in the pipe and thus restricting the discharge of fumes. Where horizontal runs are required, install the pipe with a gradual rise of 41.7 mm/m, (½ in/ft) slope from the engine. The weight of the vent pipes will require separate off-engine supports as part of the installation design. Further additional flexible connections will need to be installed to accommodate the engine movement. The pipe should vent directly into the atmosphere at a well-considered location and be fitted with a gooseneck or similar arrangement to keep rain or water spray from entering the engine. Consideration should also be given to other equipment

located near the discharge area. If not located properly, the oil carryover can accumulate over time and become unsightly. An oil condensate trap, as shown on the following drawing, will minimize the amount of oil discharged from the vent pipe. The crankcase pressure should not vary more than 25.4 mm H2O (1.0 in. H2O) of water from ambient barometric pressure. Measurement should be made at the engine dipstick location with the engine at operating temperature and minimum at 80%-90% of rated load.

Fuel System General
The fuel system utilizes unit injectors to deliver the correct amount of fuel to the cylinder at the precise moment it is needed, enabling the C280 diesel engine to produce maximum power at maximum efficiency with a minimum of exhaust emissions.
Internal Fuel System
The main fuel system components are the engine driven transfer pump, secondary duplex media type fuel filters (5 micron), fuel unit injectors and a fuel backpressure regulator. A manual fuel priming pump is also available. This pump is recommended if no electrical priming pump is available. Fuel Transfer Pump The engine driven fuel transfer pump is a gear type pump that delivers the fuel through the filters to the injectors. The recommended delivery pressure to the injectors is 800 to 840 kPa (116 to 122 psi) at rated load and speed for C280 engines. The delivery pressure is controlled by adjusting the fuel pressure regulator setting on site during commissioning of the engine. The pump is equipped with a pump mounted safety valve and the fuel flow at rated rpm is listed in the technical data and varies with engine speed. The pump is mounted on the left hand side. Unit Injectors (EUI) The electronically controlled fuel unit injectors combine the pumping, metering and injecting elements into a single unit mounted in the cylinder head. External manifolds supply low pressure fuel from the transfer pump to the cylinder heads. High pressure lines are not used. A 100 micron edge type filter is built into each unit injector.
External Fuel System Design Considerations
Diesel fuel supply systems must ensure a continuous and clean supply of fuel to the engine’s fuel system. The fuel system is designed for distillate fuel, requiring viscosity ranging from 1.4 cSt to 20 cSt at 38°C (100°F).The external fuel system typically has three major components: a fuel storage system, a fuel transfer system and fuel filtration system; and each of these systems demand careful attention to ensure the success of each installation. Fuel Storage System
©2010 Caterpillar® All rights reserved.
COOLING SYSTEM
Tank Location The tanks should not exceed the height of the engine fuel injectors in order to prevent possible leakage of fuel into the cylinders. If a higher position is unavoidable, then an auxiliary fuel tank or head limiting tank may be required. Otherwise, check valves with backpressures set to the fuel column height must be installed. Caterpillar fuel transfer pumps lifting capability is equivalent to 40 kPa (6 psi) inlet restriction.
71
C280 MARINE PROJECT GUIDE Fuel Transfer System Line Restriction The piping carrying fuel to the fuel transfer pump and the return line carrying excess fuel to the tank should be no smaller than the engine connections. The maximum inlet flow restriction is 20 kPa (3 psi) at rated speed. Air in the system causes hard starting, erratic engine operation and will erode injectors. Return Line The return line should enter the top of the tank without shutoff valves. Bypass (return) fuel leaving the engine pressure regulator should be returned to the engine day tank. If the return fuel is cooled and not returned to the day tank, provisions must be made to have the piping system vented for entrapped air and gasses. Fuel Filtration System Primary Fuel Filter Caterpillar recommends the use of a primary filter/strainer prior to the engine transfer pump and offers a duplex, primary filter (178 micron) for this purpose. Water Separation Caterpillar also recommends the use of a water and sediment separator in the supply line ahead of the transfer pump, and offers a Racor filter/water separator for this purpose. Miscellaneous Fuel System Considerations Flexible Connections Connections to the engine must be flexible hose and must be located directly at the engine inlet and outlet to accommodate engine motion.
COOLING SYSTEM
Fuel Temperature Engines are power set at the factory with 30°C ± 3°C (86°F ±5°F) fuel to the engine transfer pump. Higher fuel temperatures will reduce fuel stop power capability. The “fuel stop” power reduction is 1% for each 5.6°C (10°F) fuel supply temperature increase above 30°C (86°F). If the engine is operating below the “fuel stop” limit, the governor will add fuel as required to maintain the required engine speed. The classification societies have a maximum return to tank fuel temperature. This temperature is related to the fuel flash point. To obtain good fuel filter life, the engine fuel supply temperature should be less than 40°C (104°F). The minimum allowable viscosity of the fuel entering the engine is 1.4 cSt.
72
Fuel Coolers The need for fuel coolers is project specific and depends greatly on day tank size and location. See the following table for fuel heat rejection data.

Cooling System General
The cooling system configuration for the Caterpillar C280 series diesel engine in marine applications can be either the separate circuit system or the combined circuit system, also referred to as the single circuit - two pump system. The selection of either of these systems is based on several criteria: 1. Applicable emission requirements, i.e. EPA Tier 2 or IMO. 2. Available sea water temperature. The heat rejection data in this project guide are based on 32°C water to the aftercooler and 45°C air to the turbocharger inlet. The cooling system is laid out for the following temperature levels: 1. 32°C (90°F) nominal water temperature to the aftercooler and oil cooler (IMO allows 32°C water with 25°C ambient sea water; and EPA Tier 2 requires 32°C water with 27°C ambient sea water). Refer to the Heat Exchanger Sizing Requirements for C280 Engines chart on page 78. 2. 90°C (194°F) nominal jacket water temperature to the cylinder block (93°C thermostatic valve is used for heat recovery applications). 3. 85°C (185°F) nominal oil temperature to bearings.
Internal Cooling System Fresh Water Pumps The C280 engine has two identical gear-driven centrifugal water pumps mounted on the front housing. The right-hand pump (viewed from the flywheel end) supplies coolant to the block and heads. The left-hand pump supplies coolant to the aftercooler and oil cooler.
External Cooling System Design Considerations
©2010 Caterpillar® All rights reserved.
COOLING SYSTEM
Coolant Flow Control The correct coolant flows are obtained by factory installed orifices on the engine, combined with proper external circuit resistance set at each site during commissioning, either with customer installed orifices or balancing valves, although a lockable plug valve is recommended. The external circuit resistance setting establishes the total circuit flow by balancing total circuit losses with the characteristic pump performance curves. Correct external resistance is very important. Too high a resistance will result in reduced flows to the aftercooler and oil cooler, and their effectiveness will decrease. If there is too low a resistance, the fluid velocity limits may be exceeded, and cavitation / early wear could be the result.
75
C280 MARINE PROJECT GUIDE Note: Factory packaged cooling systems eliminate the need for the customer to set external resistance for engine cooling circuits at site. Proper flow rates for the engine cooling circuits of a factory packaged cooling system are designed by Caterpillar and tested during the Factory Acceptance Test. Listed below are the recommended external resistance maximum pressure drops for C280 engines. C280-6 and C280-8 Combined Circuit Engine Speed RPM 1000 900

Coolant Temperature Control The C280 engine uses fluid inlet control temperature regulators to provide uniform coolant temperature to the aftercooler, oil cooler, and cylinder block. For the combined circuit system, the AC/OC circuit is externally regulated to provide a nominal 32°C (90°F) coolant temperature. The high temperature jacket water system uses the AC/OC outlet water to maintain 90°C (194°F) inlet water to the block. For the separate circuit system, both the AC/OC and jacket water systems are externally regulated, using sea water to maintain the required 32°C (90°F) AC/OC and 90°C (194°F) jacket water temperatures. Sea Water Pump (customer furnished) The seawater pump is typically supplied by the customer because the optionally supplied Caterpillar engine mounted sea water pump does not have sufficient suction capability to lift water from sea level to the engine room on a typical offshore platform. Expansion Tanks Expansion tanks are available from Caterpillar as standard options. The combined circuit expansion tank is full flow. The separate circuit expansion tank is full flow for the jacket water circuit and the AC/OC circuit is a shunt type connection. Note that a single expansion tank is used to provide water and venting for both circuits. System Capacities Engine

C280 MARINE PROJECT GUIDE Heat Exchangers Caterpillar offers heat exchangers of the plate and frame type. Heat exchanger sizing and performance depends on emission requirements, water flow and temperature differential. Control of the sea water velocity must be maintained to avoid erosion problems with the heat exchangers. Heat Exchanger Sizing The minimum acceptable heat exchanger configuration for either the separate circuit system or combined circuit system must provide coolant temperature at the AC/OC pump inlet in accordance with applicable emission requirements, and must consider the following: 1. Maximum expected ambient temperature 2. Maximum engine power capability (rack stop setting) 3. Maximum expected sea-water temperature 4. Expected sea-water fouling factor 5. Anticipated coolant composition (i.e. 50% glycol).
COOLING SYSTEM
See the technical data section of this project guide for specific heat rejection figures. For more reference, refer to the following Heat Exchanger Sizing Chart.

Jacket Water Heaters Jacket water heaters may be required to meet cold starting and load acceptance criteria. To provide for the optimum usage of the heater, Caterpillar routes the heater water into the top of the cylinder block and exit at the bottom to maintain block temperature. Caterpillar offers an optional 15 kW heater for C280-06 engine installations, and a 30 kW heater for C280-08 and larger engine installations. System Pressures Correct cooling system pressure minimizes pump cavitation and increases pump efficiency. The combination of static and dynamic pressure heads must meet the pressure criteria listed in the technical data. Venting Proper venting is required for all applications. Vent lines should be routed to an expansion tank at a constant upward slope. System Monitoring During the design and installation phase it is important that provisions are made to measure pressure and temperature differentials across major system components. This allows accurate documentation of the cooling system during the commissioning procedure. Future system problems or component deterioration (such as fouling) are easier to identify if basic data is available. Serviceability Suitable access should be provided for cleaning, removal or replacement of all system components. Isolation valves should be installed as deemed necessary to facilitate such work.

C280 MARINE PROJECT GUIDE Heat Recovery Water Maker For engines with a Combined Circuit Cooling System, heat recovery connections are available with a 3-way thermostatic valve for the customer to route Jacket Water (or High Temperature) Circuit water from the outlet of the engine block to a water maker heat exchanger and then return the water to an inlet on the combined circuit mix box (temperature regulator) on the engine. There are optional 93°C (199°F) jacket water thermostats for heat recovery available. See connection drawings on pages 86 and 87. Also available by DTO quotation is a single connection (part number 102-3719) for the Vee engines to provide RH or LH connection; Refer to the drawing on page 88 for this option. For engines with a Separate Circuit Cooling System, heat recovery connections are not required, as the Jacket Water (or High Temperature) Circuit is already isolated. For both types of cooling systems, Caterpillar is able to provide a complete cooling system to include a water maker heat exchanger, heat recovery circuit temperature regulator and required piping to meet the customer’s project specific needs.
Generator Cooling
Generators can be furnished either air cooled or water cooled. Air cooled generators must be included in the ventilation system sizing considerations. Water cooled generators are typically sea water cooled; Similar to the engine’s sea water pump, the generator sea water pump will be customer furnished. This pump must have sufficient suction capability to lift water from sea level to the engine room on a vessel. Depending on the overall cooling system configuration, generator cooling water can be supplied from a separate pump or combined with the engine’s sea water pump supply capacity.
Cooling Water Requirements
COOLING SYSTEM
Water Quality, Rust Inhibitors and Antifreeze Maintaining water quality is very important in closed cooling systems. Excessive hardness will cause deposits, fouling and reduced effectiveness of cooling system components. Caterpillar has available coolant inhibitor to properly condition the cooling water. When using Caterpillar inhibitor, the cooling water piping must not be galvanized and aluminum should not be used. If the piping is galvanized, the zinc will react with the coolant inhibitor and form clogs, which will interfere with the system operation.

Starting Air System General
The Caterpillar C280 Series engine supplied air starting system includes TDI turbine type air starters, air relay valve, solenoid valve, strainer, shut off valve and optional pressure regulator, if required. One TDI turbine type air starter is needed for inline and 12 cylinder engines, while two are needed for the 16 cylinder engines. For starting with gear boxes and drive line loads attached to the engine there are optional dual starters for the 12 cylinder and Heavy Duty single starters available for the inline engines. The turbine driven air motor is highly reliable, tolerant of debris and does not require external lubrication.
Engine Starting Air System
The standard TDI turbine starters operate on air inlet pressures from 6.2 to 10.4 bar (90 to 150 psi). These pressures are required at the starter inlet port. An air tank pressure below 7 bar (100 psi) will generally not start the engine because of the pressure drop associated with the air supply lines. For initial system evaluation, assume a 2 bar (29 psi) pressure drop between the tank and the air starter inlet. A pressure regulator (available as an option in the pricelist) is necessary when the supply pressure exceeds the starter dynamic operating pressure. The pressure regulator should be set from 6.2 to 10.4 bar (90 to 150 psi). Inline engines should have the capacity to flow 450 l/sec (15.9 ft3/sec) per starter at regulator inlet pressure of (90 psi) (regulators with a Cv factor of 40 or higher are required). The quantity of air required for each start and the size of the air receiver depend upon cranking time and air-starter consumption. A typical first start at 25°C (77°F) ambient will take five to seven seconds. Restarts of warm engines normally take place in three to four seconds. The control system will shut off the air to the air starters at 170 rpm engine speed. At this firing speed, the governor is activated to allow fuel to the engine. Large or complex drive lines can increase starting air volume required by 20 or 30 percent depending on loads on the engine during starting. Gearbox designs can have a significant impact on the starting loads if connected during starting especially if driving a shaft driven generator.
Starting Air System Design Considerations
The size of the air receivers should be increased if the starting air receiver also supplies air for purposes other than the main engine starting (e.g. engine air prelube, work air, auxiliary gensets). The Caterpillar intermittent air prelube pump consumption rate is 28.2 l/sec (1 ft3/sec) based on free air at 21°C at 100 kPa ©2010 Caterpillar® All rights reserved.
STARTING AIR SYSTEM
The following charts are for estimating typical air receiver sizing for starting anengine only. The chart shows the estimated number of starts available with an initial starting air receiver pressure as shown on the curves. The starting air receiver size is normally determined by the requirements of the classification society for the number of starts or start attempts. Refer to the Air Supply Line Sizing section for additional information.
97
C280 MARINE PROJECT GUIDE (77°F at 76 psi). The pump motor operating pressure is 690 kPa (100 psi). With the redundant prelube system and the continuous prelube pump running at startup, the pneumatic intermittent prelube pumps for the engine and generator will operate for no longer than 15 seconds. For generator sets with pneumatic intermittent prelube pump only, the prelube pump will normally operate 1 to 5 minutes before the engine begins to crank.

Air Supply Line Sizing
TDI turbine starters must be supplied with clean dry air. Deposits of oil-water mixture must be removed by traps installed in the lines. Lines should slope towards the traps and away from the engine. Air supply lines should be routed and sized to ensure adequate pressure and flow at the starter(s). As a general rule, the air supply pipes should be short with number of elbows kept to a minimum to reduce pressure loss to the starter.
For dual starting motor systems the customer connection is 3 inch ANSI flange. A 3 inch supply line size is minimum required. A flexible connection between engine starting line and supply line should always be used to prevent vibration induced fatigue.

STARTING AIR SYSTEM
For single starting motor systems the customer connection is either 1½ inch or 2 inch NPT. A 2 inch (minimum) supply line size is required and recommend a customer-provided 3 inch supply air line for installations with more than 50 ft (15 m) of equivalent straight length of pipe from receiver or regulator to air starter.
101
C280 MARINE PROJECT GUIDE If a pressure reducing valve is required, a valve with Cv40 should be used to provide sufficient air flow. Locate the pressure reducing valve as close to the engine as possible to minimize the air pressure reduction valve supply pipe diameter. Water and oil must be removed frequently from air supply source to prevent possible damage to the starting system components.

Combustion Air System General
The aftercooler system is a High Performance Air Cooling (HPAC) system designed in a modular layout. The aftercooler inlet section is insulated with a soft wrap insulation to comply with Marine Society rules for surface temperature. The top covers of the three aftercooler sections are provided with a screen for protection and insulation. The flexible bellow joints are connected by means of Vshaped clamps and the use of metallic C-rings. The maximum inlet air temperature to the turbocharger is 49°C (120°F). This temperature is in accordance with the Marine Society rules for equipment performance and will provide good engine component life. For temperatures above 30°C (86°F), the engine may be derated to a power output level that will provide for safe engine operation; check with Caterpillar A&I Engineering. The C280 Engine will normally draw engine combustion air in one of two ways: 1. The engine room is supplied with filtered air for engine combustion as well as for removal of radiated heat from the engine room. 2. The engine room is supplied with ventilation air for engine heat removal and the engine combustion air is supplied separately through a dedicated air intake system, which provides filtered air for the combustion only. Either system should be designed to provide sufficient clean air for combustion and heat removal based on the ambient conditions and the maximum ratings for each piece of installed equipment (i.e. marine auxiliary engines, pumps, and switchgear). For classed vessels, the specific societies have well defined rules for the design parameters.
Combustion Air System Design Considerations Engine Room Supplied Air The location and design of the engine room air intakes should consider the following: 1. The supply air outlets should be close to and directed at the engine turbocharger air intakes.
3. The engine room air inlets should be placed such that water or dirt cannot enter. Separate Combustion Air System Supplying the engines with direct outside air for combustion if possible is beneficial to the installation for a number of reasons. It will bring down the air movement in the engine room, may reduce the cooling load on the charge air cooler and thus reduce the maximum heating load on the cooling water heat exchanger. This in turn will reduce the required sea water circulation in the system. Direct air to the turbocharger inlet will provide a bigger margin to the point where engine load ©2010 Caterpillar® All rights reserved.
COMBUSTION AIR SYSTEM
2. Additional air should flow along the engine, coupling, and reduction gear to absorb the radiated heat.
103
C280 MARINE PROJECT GUIDE reduction is needed due to high air inlet temperatures. It would be expected that if the turbocharger inlets are supplied with engine room supplied air a temperature rise above ambient of 5 to 10°C (9 to 18°F) would take place. By supplying the engines with direct outside air the vessel will also save on the required fan work. If the engine combustion air is supplied through a separate, dedicated air system, the engine room design should consider the following. 1. The entire intake system, including clean air filters should have an initial restriction of no greater than 122 mm H2O (4.8 in. H2O). 2. The maximum inlet restriction with dirty air filters should not exceed 380 mm H2O (15 in. H2O). 3. Flexible connections are necessary to isolate engine vibration from the ducting system. Locate the flex connection as close to the engine as possible, but be aware of the excessive heat generated by the exhaust system. 4. Avoid supporting excessive lengths of ductwork off the turbocharger. The maximum allowable moment on the turbocharger is 300 Nm (221 ft-lb). 5. Caterpillar has specially designed the air intake components to provide the proper airflow pattern before the turbocharger. Turbocharger performance may be adversely affected if these components are not used. General The amount of combustion air necessary for the C280 engine is specified in the technical data section of this manual. The amount of radiated heat emitted by each engine is also specified.
COMBUSTION AIR SYSTEM
Installations intended for operation in extreme cold may require heated air for starting purposes. In addition, it may be necessary to control the inlet boost pressure for cold air installations. Contact your Caterpillar dealer or the regional Caterpillar representative for further information when extreme ambient conditions are expected.

Engine Room Ventilation General
Although not part of the Caterpillar Scope of Supply for a typical diesel generator package, the engine room ventilation system is a vital part of a successful installation. The two primary aspects of a properly designed engine room ventilation system addressed in this document are cooling air and combustion air. •
Cooling Air: The flow of air required to carry away the radiated heat of the engine(s) and other engine room machinery.
•
Combustion Air: The flow of air required to burn the fuel in the engine(s).
Both of these have a direct impact on an engine’s or packaged unit’s performance, and must be considered in the design of an engine room ventilation system. However, it is important to note that all equipment within the engine room space, not only the diesel generator packages, must be given consideration in the overall ventilation system design process.
Sizing Considerations Cooling Air Engine room ventilation air (cooling air) has two basic purposes: •
To provide an environment that permits the machinery and equipment to function properly with dependable service life.
•
To provide an environment in which personnel can work comfortably.
ENGINE ROOM VENTILATION
A small percentage of fuel consumed by an engine is lost to the environment in the form of heat radiated to the surrounding air. In addition, heat from generator inefficiencies and exhaust piping can easily equal engine radiated heat. Any resulting elevated temperatures in the engine room may adversely affect maintenance, personnel, switchgear, and engine or generator set performance. The use of insulated exhaust pipes, silencer, and jacket water pipes will reduce the amount of heat radiated by auxiliary sources.
108
Radiated heat from the engines and other machinery in the engine room is absorbed by engine room surfaces. Some of the heat is transferred to atmosphere, but the remaining radiated heat must be carried away by the ventilation system. A system for exhausting ventilation air from the engine room must be included in the ventilation system design. The engine(s) will not be able to carry all of the heated ventilation air from the engine room by way of the exhaust piping. Combustion Air In many installations, combustion air is drawn from outside of the engine room via ductwork, in which case, the combustion air is not a factor in the ventilation system design calculations. However, many installations require that combustion air be drawn directly from the engine room. In these installations, combustion air requirements become a significant ventilation system design parameter. Engine specific combustion air requirements can be found in the Technical Data section for the specific engine and rating. ©2010 Caterpillar® All rights reserved.
Ventilation Air Flow Required ventilation air flow depends on the desired engine room air temperature as well as the cooling air and combustion air requirements outlined above. While it is understood that total engine room ventilation air flow must take all equipment and machinery into account, the following sections provide a means for estimating the air flow required for the successful operation of Caterpillar engines and packages. In general, changing the air in the engine room every one or two minutes will be adequate, if flow routing is proper. Provisions should be made by the installer to provide incoming ventilation air of 0.1 to 0.2 m3/min (4 to 8 cfm) per installed horsepower. This does not include combustion air for the engines.
Engine Room Temperature
A properly designed engine room ventilation system will maintain engine room air temperatures within 8.5 to 12.5°C (15 to 22.5°F) above the ambient air temperature (ambient air temperature refers to the air temperature surrounding the power plant, vessel, etc.). Maximum engine room temperatures should not exceed 49°C (120°F). If they do, then outside air should be ducted directly to the engine air cleaners. The primary reason for cooling an engine room is to protect various components from excessive temperatures. Items that require cool air are: •
Electrical and electronic components
•
Air cleaner inlets
•
Torsional dampers
•
Generators or other driven equipment
•
Engine room for the engine operator or service personnel.
In larger multiple engine sites, the normal 8.5 to 12.5°C (15 to 22.5°F) temperature rise guidelines for engine rooms may require unobtainable or uncomfortable air velocities. For these larger sites, a ventilation system that gives priority to the five items listed above and provides a bottom to top air flow can be designed for a temperature rise of 17°C (30°F).

C280 MARINE PROJECT GUIDE Radiant Heat Engine Radiant Heat Engine generated heat must be taken into consideration. This information can be found on the Engine Technical Data Sheets.

Ventilation Fans
In modern installations, except for special applications, natural draft ventilation is too bulky for practical consideration. Adequate quantities of fresh air are best supplied by powered (fan-assisted) ventilation systems. Fan Location Fans are most effective when they withdraw ventilation air from the engine room and exhaust the hot air to the atmosphere. However, ideal engine room ventilation systems will utilize both supply and exhaust fans. This will allow the system designer the maximum amount of control over ventilation air distribution. Fan Type Ventilation fans are typically of the vane-axial, tube-axial or propeller type, or the centrifugal type (squirrel cage blowers). The selection of fan type is usually determined by ventilation air volume and pressure requirements, and also by space limitations within the engine room. When mounting exhaust fans in ventilation air discharge ducts, which are the most effective location, the fan motors should be mounted outside the direct flow of hot ventilating air for longest motor life. The design of centrifugal fans (squirrel cage blowers) is ideal in this regard, but their size, relative to the vane-axial or tube-axial fans, sometimes puts them at a disadvantage. Fan Sizing Fan sizing involves much more than just selecting a fan that will deliver the air flow volume needed to meet the cooling air and combustion air requirements determined earlier in this section. It requires a basic understanding of fan performance characteristics and ventilation system design parameters.
Exhaust Fans
Ventilation air exhaust systems should be designed to maintain a slight positive or negative pressure in the engine room, depending on the specific application.
©2010 Caterpillar® All rights reserved.
ENGINE ROOM VENTILATION
Similar to a centrifugal pump, a fan operates along a specific fan curve that relates a fan’s volume flow rate (m3/min or cfm) to pressure rise (mm H2O or in. H2O) at a constant fan speed. Therefore, fan selection not only requires that the volume flow rate be known, but also that the ventilation distribution system be known in order to estimate the system pressure rise. This information allows the optimum fan to be selected from a set of manufacturers’ fan curves or tables.
111
C280 MARINE PROJECT GUIDE Generally, maintaining a slight positive pressure in the engine room is recommended, but should normally not exceed 50 Pa (0.2 in. H2O). This positive pressure accomplishes several things: •
It prevents the ingress of dust and dirt, which is especially beneficial for those applications involving engines that draw their combustion air from the engine room.
•
It creates an out draft to expel heat and odor from the engine room.
Some applications require that a slight negative pressure be maintained in the engine room, but normally not in excess of 12.7 mm H2O (0.5 in. H2O). The excess exhaust ventilation air accomplishes several things: •
It compensates for the thermal expansion of incoming air.
•
It creates an in draft to confine heat and odor to the engine room.
Two Speed Fan Motors Operation in extreme cold weather may require reducing ventilation airflow to avoid uncomfortably cold working conditions in the engine room. This can be easily done by providing ventilation fans with two speed (100% and 50% or 67% speeds) motors.
Routing Considerations
Correct ventilation air routing is vital for creating and maintaining the optimum engine room environment required to properly support the operation of Caterpillar engines and packaged units. Maintaining recommended air temperatures in the engine room is impossible without proper routing of the ventilation air. Fresh air inlets should be located as far from the sources of heat as practical and as high as possible; and since heat causes air to rise, it should be exhausted from the engine room at the highest point possible, preferably directly over the engine.
ENGINE ROOM VENTILATION
Where possible, individual exhaust suction points should be located directly above the primary heat sources in order to remove the heat before it has a chance to mix with engine room air and raise the average temperature. However, it must be noted that this practice will also require that ventilation supply air be properly distributed around the primary heat sources.
112
Avoid ventilation air supply ducts that blow cool air directly toward hot engine components. This mixes the hottest air in the engine room with incoming cool air, raising the temperature of all the air in the engine room, and leaves areas of the engine room with no appreciable ventilation. For offshore applications, where the potential exists for sea water to be drawn into the ventilation air supply, the combustion air should be delivered in a manner that will preclude any sea water from being ingested by the turbochargers through the air intake filters. These General Routing Principles, while driven by the same basic principles of heat transfer, will vary with the specific application. This section discusses the general considerations relating to 1 and 2 engine applications, multiple engine (3+) applications, and several special applications. ©2010 Caterpillar® All rights reserved.
1 and 2 Engine Applications These applications will generally require smaller engine rooms, which may sometimes preclude the use of good routing practices. Recommended ventilation systems for these applications, presented in order of preference, are described below: Ventilation Types 1 and 2 (Preferred Design) Outside air is brought into the engine room through a system of ducts. See Figure 1. These ducts should be routed between engines, at floor level, and discharge air up at the engines and generators. The most economical method is to use a service platform, built up around the engines, as the top of this duct. See Figure 2. This requires the service platform to be constructed of solid, nonskid plate rather than perforated or expanded grating. The duct outlet will be the clearance between the decking and oilfield base. Ventilation air exhaust fans should be mounted or ducted at the highest point in the engine room. They should be directly over heat sources. This system provides the best ventilation with the least amount of air required. In addition, the upward flow of air around the engine serves as a shield which minimizes the amount of heat released into the engine room. Air temperature in the exhaust air duct will be higher than engine room air temperature. Ventilation Type 3 (Alternate Design) If Ventilation Types 1 or 2 are not feasible, the following method is recommended; however, it will require approximately 50% more air flow: Outside air is brought into the engine room as far away as practical from heat sources, utilizing fans or large intake ducts. The air is discharged into the engine room as low as possible. See Figure 3. Allow air to flow across the engine room from the cool air entry point(s) toward sources of engine heat such as the engine, exposed exhaust components, generators, or other large sources of heat. Ventilation air exhaust fans should be mounted or ducted at the highest point in the engine room. Preferably, they should be directly over heat sources. Engine heat will be dissipated with this system, but a certain amount of heat will still radiate and heat up all adjacent engine room surfaces.
This system will work only where the air inlets circulate the air between the engines, for 2 engine applications. Air inlets located at the end of the engine room will provide adequate ventilation to only the engine closest to the inlet. Ventilation Type 4 (Alternate Design) If Ventilation Types 1, 2 or 3 are not feasible, the following method can be used; however, it provides the least efficient ventilation and requires approximately 2.5 times the air flow of Ventilation Types 1 and 2: Outside air is brought into the engine room using supply fans, and discharged toward the turbocharger air inlets on the engines. See Figure 4. ©2010 Caterpillar® All rights reserved.

If the air is not properly routed, it will rise to the ceiling before it gets to the engines.

C280 MARINE PROJECT GUIDE Ventilation exhaust fans should be mounted or ducted from the corners of the engine room. This system mixes the hottest air in the engine room with the incoming cool air, raising the temperature of all air in the engine room. It also interferes with the natural convection flow of hot air rising to exhaust fans. Engine rooms can be ventilated this way, but it requires extra large capacity ventilating fans.

In general, the recommended ventilation systems outlined for 1 and 2 engine applications also apply to multiple engine applications. However, there are several additional considerations that are specific to multiple engines. As previously mentioned, the application of normal temperature rise guidelines for determining large multiple engine site ventilation requirements will generally result in extremely large volumes of air. Therefore, the guidelines used for these sites are significantly more generous; however, even with the increased temperature rise allowed, the ventilation requirements will be significant. Large multiple engine sites will generally utilize multiple ventilation fans, often using one or two fans for each engine. This practice allows for a very simple arrangement requiring minimal ductwork. ©2010 Caterpillar® All rights reserved.
ENGINE ROOM VENTILATION
Multiple Engine (3+) Applications Multiple engine applications, involving three or more engines or packaged units, will generally require larger engine rooms than those needed for 1 and 2 engine applications.
115
C280 MARINE PROJECT GUIDE The use of multiple ventilation fans, either supply or exhaust, will require that air flow between the engines be arranged, either by fan placement or by distribution ductwork. Figure 5 and Figure 6 show examples of correct and incorrect air flow patterns for multiple engine sites. Correct Air Flow

Exhaust System General
The C280 engine uses a pulse exhaust manifold system. The front and rear three cylinders are connected to separate turbine inlets.
Exhaust System Design Considerations Exhaust Backpressure Limits The total C280 exhaust backpressure limit is 254 mm H2O (10 in H2O). This level was established with an emphasis on low specific fuel consumption and exhaust valve temperatures. Therefore, to achieve proper performance of the engine, the exhaust backpressures must be kept below this limit. System backpressure should be measured in a straight length of the exhaust pipe at least 3 to 5 pipe diameters away from the last size transition from the turbocharger outlet. System backpressure measurement is part of the engine commissioning. Turbochargers For the single turbocharger 6 cylinder engine and the two turbocharger 12 cylinder engine, the turbochargers are located at the flywheel end of the engine. The turbocharger exhaust outlet is rectangular with an area equivalent to 311 mm (12 in.) diameter. A cast adapter mounts to each turbocharger to provide a 355 mm (14 in.) diameter customer connection point. Optional attachments for these turbochargers include 355 mm (14 in.) diameter flexible bellows, expansion transitions from 355 mm (14 in.) to 457 mm (18 in.) diameter, 457 mm (18 in.) diameter bellows, and exhaust flanges with bolting and mounting hardware. For the single turbocharger 8-cylinder engine and the two turbocharger 16cylinder engine, the turbochargers are located at the flywheel end of the engine. The turbocharger exhaust outlet is 355 mm (14 in.) diameter with cast adaptors mounted to each turbocharger to provide a 457 mm (18 in.) diameter customer connection point. Optional attachments for these turbochargers include 355 mm (14 in.) diameter flexible bellows, 457 mm (18 in.) diameter bellows, and exhaust flanges with bolting and mounting hardware. Additionally, there is an optional two turbocharger 16-cylinder engine with the turbochargers mounted opposite the flywheel end of the engine for a front mounted turbo engine configuration. This engine includes the same cast adaptors and options as the previously mentioned rear mounted turbo engine configuration.
Exhaust Slobber (Extended Periods of Low Load) Prolonged low load operation should be followed by periodic operation at higher load to burn out exhaust deposits. Low load operation is below 400 kPa bmep (58 ©2010 Caterpillar® All rights reserved.
EXHAUST SYSTEM
The exhaust bellows are intended to compensate for thermal growth and movement of the engine. The exhaust system structure immediately after the engine exhaust bellows must be a fixed, rigid point. The supplied exhaust bellows will only handle the engine movement and thermal growth. No additional external loading is allowed on the turbochargers.
117
C280 MARINE PROJECT GUIDE psi bmep) (approximately 20% load, depending on rating). The engine should be operated above 800 kPa bmep (116 psi bmep) (about 40% load, depending on rating) periodically to burn out the exhaust deposits. The amount of additional time depends upon the engine configuration, water temperature to the aftercooler, inlet air temperature to the engine and type of fuel. Engine Operation at Idle or Low Load Conditions Absolute Idle (declutched and/or disconnected): •
Maximum of 10 minutes if the engine is going to be stopped – 3 to 5 minutes of idling is recommended prior to shutdown.
•
Maximum of 4 hours if the engine is to be loaded after idling.
Operation below 10% load on recommended distillate diesel fuels: •
Engine can be run for 100 hours, and then should be taken to a minimum load of 70% for 1 hour; then the engine can be returned to idle at the low load condition.
Operation above 10% load on recommended distillate diesel fuels: •
No restrictions
Exhaust Piping A common exhaust system for multiple installations is not acceptable. An exhaust system combined with other engines allows operating engines to force exhaust gases into engines not operating. The water vapor condenses in the cold engines and may cause engine damage. Additionally, soot clogs turbochargers, aftercoolers, and cleaner elements. Valves separating engine's exhaust systems are also discouraged. High temperatures warp valve seats and soot deposit causes leakage.
EXHAUST SYSTEM
The exhaust pipe diameter is based on engine output, gas flow, and length of pipe and number of bends. The maximum gas velocity should not exceed 50 m/s (164 ft/sec) at full load. Sharp bends should be avoided, and where necessary, should have the largest possible radius. The minimum radius should be 1½ pipe diameters. The piping should be as short as possible and insulated. The insulation should be protected by mechanical lagging to keep it intact. All flexible exhaust fittings should be insulated using removable quilted blankets. It is recommended to provide the system with a valve drain arrangement to prevent rainwater from entering the engine during prolonged shutdown periods. For testing purposes, the exhaust system must have a test port installed after the turbocharger outlet. This test port should be a 10 to 13 mm (0.39 to 0.51 in.) plugged pipe welded to the exhaust piping and of sufficient length to bring it to the outer surface of the insulated piping.
118
Exhaust piping must be able to expand and contract. It is required that one fixed point be installed directly after the flexible exhaust fitting at the turbocharger outlet. This will prevent the transmission of forces resulting from weight, thermal expansion or lateral displacement of the external exhaust piping from acting on the turbocharger.

Engine Piping Connections
For the single turbocharger 6 cylinder engine and the two turbocharger 12 cylinder engine, the turbocharger exhaust outlet is rectangular with an area equivalent to 311 mm (12 in.) diameter. For the single turbocharger 8-cylinder engine and the two turbocharger 16cylinder engine, the turbocharger exhaust outlet is 355 mm (14 in.) diameter with cast adaptors mounted to each turbocharger to provide a 457 mm (18 in.) diameter customer connection point.

C280 MARINE PROJECT GUIDE
Engine Monitoring and Shutdown Engine Shutdown
The C280 engine is installed with shutdown protection for overspeed, low lubrication oil pressure, high crankcase pressure, high jacket water temperature, and Metal Particle Detection. High oil mist level alarm and/or shutdown are available as an option to satisfy marine societies which typically require this feature on engines above 2250 bkW. In addition, the engine can be shut down through the electrical control system via emergency shutdown buttons installed as required by the Marine Classification Society on the bridge and the engine control panel. For the shutdowns, the engine is stopped via the shutdown solenoid in the governor. However in case of an overspeed or activated emergency stop button, the engine will be stopped by an emergency air shutoff system. Both of these measures are taken as a precaution and to fulfill society requirements. The engine safety system is operationally independent from the monitoring system. That means the engine will shut down for the safety functions, high crankcase pressure, overspeed and low lubrication pressure even when the PLC is not operational.
Engine Monitoring
Engine monitoring switches and analog sensors (4-20 mA transmitters, RTD’s, switches, and thermocouples) can vary from one installation to the next.
ENGINE MONITORING AND SHUTDOWN
Pressure Sensors The engine is installed with a sensor package in accordance with the sensor list enclosed. The pressure sensors are generally mounted on a common panel on either the front or side of the engine.
130
Temperature Sensors The exhaust temperature sensors are thermocouples and the remaining sensors are RTD's (PT100). Engine Control Panel The Engine Control Panel contains the PLC, start / stop logic and man-machine interface (MMI) touch screen for displaying the operating parameters. The operator is able to view engine parameters from different screens for each system (exhaust, water, and air) on the engine. The various screens are called to view by buttons located at the bottom of each screen. All the engine parameters are further available to the vessel control system via P/C communications. The monitoring and alarm functions listed in the instrumentation list overleaf are typical for a C280 Marine engine supply, Marine Classification Society with notation: Unmanned Machinery Space (UMS).

Engine Mounting and Foundation Design Propulsion Engine Mounting and Foundation
This section discusses propulsion engine and reduction gear foundations and their relationship to ship framing. Exact analytical methods cannot always be used to design engine foundations. The design is also influenced by several factors, including previous successful installations, the designer's experience, and the basic dimensions of the specific engine being installed. Refer to this guide for specific information on C280 Engine weights and dimensions. The engine foundation must resist vertical, horizontal and fore-and-aft deflection. It should also be integrated into the reduction gear foundation to connect the overall structure to the ship's inner bottom structure. In this manner, the thrust from the propeller, and the dynamic forces from the main engine and reduction gear are evenly distributed over a large area of the inner bottom structure. If the engine foundation has too little resistance against deflection, it may show up during the alignment of the engines as the mount depressions may be influenced by the combination of foundation deflection and engine forces, and may be out of tolerance. The main engine foundation must have sufficient rigidity to transmit static and dynamic forces from the main engine into the foundation. The girder and faceplate must: increase bending inertia of the structure
•
facilitate chock installation
•
provide a "work shelf" for servicing the side of the engine
•
permit installation of side blocks and collision chocks
The main engine and reduction gear foundation must also be designed to absorb the loads from: •
ship's vibration
•
propeller thrust
•
thrust and torque of the engine
•
ship’s motion at sea
•
thermal, static and dynamic effects
•
crash reversal
Because the loads originate from sources other than the engine, the foundation sections should be uninterrupted and have adequate section strength. To avoid natural frequency resonance between engine and hull, the engine's 1st and 2nd order free forces and moments must be taken into account when designing the mounting structure. The ship builder must ensure that resonance between torque excitation and the natural transverse hull frequencies does not ©2010 Caterpillar® All rights reserved.

Auxiliary Engine/Package Mounting and Foundation
This section describes packaged generator set foundations and their relationship to platform framing. Exact analytical methods cannot always be used to design foundations. The design is also influenced by several factors, including previous successful installations, the designer's experience, and the basic dimensions of the specific package being installed. C280 packaged generator set weights can vary from 38,900 kg (86,000 lb) for a 6-cylinder, low voltage package with air cooling (excluding radiator weight) up to 95,500 kg (210,000 lb) for a 16-cylinder, high voltage package including a platetype heat exchanger cooling system and generator forced lubrication module. The generator set foundation must resist vertical, horizontal and fore-and-aft deflection. If the engine foundation has too little resistance against deflection, it may show up during the alignment of the engines as the mount depressions may be influenced by the combination of foundation deflection and engine forces, and may be out of tolerance. The generator set foundation must have sufficient rigidity to transmit static and dynamic forces from the package into the foundation. Mounting C280 packaged generator sets are furnished on Caterpillar designed rigid bases in order to maintain alignment between engine, generator and other engine driven equipment, and must be mounted on spring isolators unless hard mounting has been approved by Caterpillar.
Generators General Caterpillar C280 Marine Generator Sets (Auxiliary and Diesel Electric Propulsion (DEP)), are packaged with free-standing two-bearing generators, matched to the engine output to provide the customer maximum electrical output to meet their requirements, as well as marine classification requirements for the application. Generator specifications and generator testing requirements will need to be reviewed during the pre-sale phase of the project and established prior to order placement. Options to be considered should include sub-transient reactance needed to meet transient responses required and type of current transformers to be mounted and supplied for the project. For generators supplied by others, generator manufacturer is responsible for providing any forced lubrication system that may be required for their generator to meet tilt requirements.

Caterpillar C280 engines have an option for Witness Testing to be conducted in the Lafayette Package test cells. No customers or dealer personnel are allowed in the test cell while the engines are running, and no customer instrumentation may be connected to the engines, packages, or test cell data acquisition and reporting systems. Standard testing includes a load test, transient response test, and vibration test, described as follows: 1. The load test uses 0.8 PF unless otherwise noted, and is recorded at 30 minute intervals. •
30 minutes @ 50% rated load
•
30 minutes @ 75% rated load
•
120 minutes @ 100% rated load
•
60 minutes @ 110% rated load, 1.0 PF The cylinder and exhaust temperatures are manually recorded. All other data is recorded electronically and printed by computer.
2. The transient response test is performed at 0.8 PF with load stepping from 0% to 100% ekW, with pre-determined intervals depending on engine frequency, then back to 0%, with examples as follows: •
For 900 rpm (60 Hz) C280-16 or 3616 engines: o 0% - 1700 ekW - 2880 ekW - 3840 ekW - 100% - 0%
•
For 1000 rpm (50 Hz) C280-16 or 3616 engines: o 0% - 1900 ekW - 3210 ekW – 4275 ekW - 100% - 0%
3. The vibration test is taken at 0% and 100% load, and printed by computer. This is a 14-point, 1-dimensional test around the operating genset package to ensure no unusual vibration is occurring on the as-built configuration. The standard testing also includes the following data as obtained through the data acquisition system. Performance Data: • rpm

•
Fill Engine Jacket Water (EJW) system with a solution of 20% VCI 379 and 80% water or equivalent solution. A regulator bypass line must be used to allow filling on both sides of the regulator. Vent and EJW system at the highest point possible to assure complete filling.
•
For engines with Separate Circuit Aftercooler (SCAC) systems fill the SCAC system with a solution of 20% VCI 379 and water or equivalent solution. Vent the SCAC system at the highest point possible to assure complete filling.
•
Drain the VCI solution from the EJW system at multiple locations to assure complete drainage. (EJW pump, 10° block face cover, oil cooler, etc.)
•
Drain the VCI solution from engines with SCAC system at the SCAC water pump. Close all EJW and SCAS system openings with the parts specified on engineering drawings.
•
Spray a mixture of 50% 1 E2359 VCI oil and 50% engine oil into the air intake or turbocharger inlet. Minimum application rate is 7.5 mL/L of engine displacement. Install covers specified on engineering drawing to seal in VCI vapors.
•
Spray a mixture of 50% 1E2359 VCI oil and 50% engine oil into the exhaust opening. Minimum application rate is 7.5 mL/L of engine displacement. Install covers specified on engineering drawing to seal in VCI vapors.
•
Fill oiler reservoir for air starter with a mixture of 50% 1 E2359 VCI Oil and 50% engine oil.
•
All other lubricating oil compartments are to be protected by 1E2359 VCI Oil by one of the following methods:
•
Run the engine for the final 3 to 5 minutes with oil which has 3 to 4% of 1 E2359 VCI Oil by volume. This oil may be drained or left in the engine. Seal VCI vapors in the engine with covers specified on engineering drawings.
•
The vapor phase of the VCI oil evaporates rapidly at engine operating conditions. If further instructions are needed, consult with the Engineering Materials Section of the Engine Division.
•
Install a mixture of 50% 1 E2359 VCI Oil and 50% engine oil in the lubricating oil compartments at the rate of 1 part of mixture per 15 parts of compartment capacity at full level. Seal VCI vapors in the engine with covers specified on engineering drawings.

•
This method can be used with an empty or partially filled lubricating oil compartment. If the compartment is already full, it may be necessary to drain some lubricant to facilitate the addition of the mixture.
•
Install 30 mL of a mixture of 50% 1 E2359 VCI and 50% engine oil in each cylinder and rotate crankshaft two turns. Tighten all fittings to the correct torque. Check the fuel system to verify that it is full of fuel. Install covers specified on engineering drawing to seal in fuel and vapors.
•
Spray a thin film of mixture of 50% 1 E2359 VCI Oil and 50% engine oil on the flywheel, ring gear, and starter pinion. To seal in vapors, install the covers specified on engineering drawings for the flywheel housing and starter opening, and the plugs specified for through holes.
•
