3600 Family
Whether your needs are marine, industrial, or electric power generation, the Caterpillar 3600 Engine Family will provide you with proven power to get the job done. The 3600 Engines are the most powerful and reliable power sources ever produced by Caterpillar. Operating economy and durability make it the logical choice; worldwide product support makes it the only choice. The 3618 Marine Propulsion Engine is the newest addition to the 3600 Family. It was specifically designed to meet the needs of our marine fast ferry customers. For more information on the new Caterpillar 3600 engine, consult your local dealer (see page 48 for publications). This pocket guide is a quick reference to determine which 3600 Engine will best meet your needs. If you should have any questions, please consult your local Caterpillar dealer. If you need assistance in finding a dealer, consult one of our Caterpillar offices (pp. 46-47).

Ratings
Generator Set Ratings Continuous Rating: Typical application is base load generator set, 8000 hrs/year, load factor < = 100%, 10% overload. Prime Power: Typical application is peak shaving, 6000 hrs/year, load factor < = 60%. Rated load (100%) usage is 1 hour in 12, 10% overload. Standby: Typical application is emergency generator set, < 200 hrs/year, 100% during emergency outage, no overload. Marine Ratings Continuous Service Rating (CSR): Typical application is U.S. inland river vessel, continuous engine operation, fuel stop power equals rated power. Maximum Continuous Rating (MCR): Typical application is tugboat, 1 hour in 12 at rated power, fuel stop power equals rated power.
Conditions
The following engine ratings are based on SAE J1995 January 1990 and ISO 3046 standard conditions of 100 kPa (99 kPa dry barometric pressure) and 25 C air. Performance and fuel consumption are based on 35 API, 16 C fuel having an LHV of 42 780 kJ/kg used at 29 C with a density of 838.9 g/L. Tolerances include -0/+5% on specific fuel consumption and 3% on brake kilowatt power at the flywheel demonstrated at the Caterpillar production test cell. The maximum inlet air temperature to the turbocharger is 45 C before derating. Engine ratings are net power and include deduction for the following parameters: cooling water pumps, lube oil pumps, fuel pump, typical exhaust restriction, and typical air filter restriction.

Pistons are two-piece with a forged steel crown and forged aluminum skirt. This piston construction ensures excellent strength and durability, and minimal weight. Pistons have four rings two in hardened grooves in the piston crown, and two in the skirt. The top ring is plasma coated; this provides extra wear resistance and lowers lube oil resistance and consumption. The two middle rings are taper faced and chrome plated. The lower oil control ring is double rail and chrome faced with a spring expander. Main bearings are made of steel backed aluminum with a nickel bonded lead/tin/copper overlay. Rillenlager technology, which alternates stripes of aluminum and overlay on the surface, is used. This provides higher load carrying capability and reduces wear rates when compared to trimetal aluminum bearings. The bearings have no grooves in the lower bearing shell. This greatly reduces unit pressure loading when compared to grooved bearings. Rod and camshaft bearings are made of steel backed aluminum with a copper bonded lead/tin overlay. Aluminum bearing material provides better characteristics in the areas of heat conduction, resistance against corrosion, and ability to embed small particles that may otherwise damage journal surfaces. Bearings have no grooves, greatly reducing unit pressure load on the bearings.
Cylinder liners are induction hardened. The combination of induction hardened liners, one chrome/plasma-coated piston top ring, and three chrome-coated piston rings provides the lowest wear on running surfaces. The 3600 liners are plateau honed for better oil control.
Cuff
Piston Rings
Located at the top of the liner is a sleeve or cuff that removes carbon deposits from the top land of the piston. This sleeve prevents the loss of oil control and reduced cylinder liner life by preventing carbon deposits from accumulating and polishing the cylinder liner. Connecting rods are forged, heat treated, and shot peened before machining. The special four-bolt design and the elimination of bearing grooves allows for an extra large bearing which reduces bearing load and extends bearing life. Valves seat on replaceable induction-hardened inserts. Rotators on all valves maintain uniform temperature and wear pattern across the valve face and seat. The exhaust valves used in heavy fuel engines are given special attention to extend their life. The exhaust valve temperature is reduced to approximately 410 C to minimize the possibility of vanadium induced corrosion. A mnemonic 80A material is used in the exhaust valve. The valve head is coated with ceramics and water-cooled valve seats are used to maintain the low valve temperatures.

Cylinder Liner
Cooling System. There are two basic cooling system configurations: single circuit and separate circuit. Both configurations include an engine mounted plate-fin aftercooler designed for high heat transfer. Both configurations include two water pumps that are engine driven from the front gear train. The right-hand pump (as viewed from the flywheel end) supplies coolant to the cylinder block, heads, and turbochargers. The left-hand pump supplies coolant to the aftercooler and oil cooler. Unit injectors eliminate the need for high pressure fuel lines. Maximum injection pressure is 1400 bar on MDO engines and 1520 bar on HFO engines. These pressures provide good fuel atomization which is required for low fuel consumption and heavy fuel operation. The 3600 unit injectors have tip cooling for heavy fuel operation.
Overhaul intervals are based on: normal wear, proper preventive maintenance, good quality lube oil, regular lube oil analysis, and load factor within defined parameters. NOTE: The above distillate intervals typically do not apply to fast vessel applications.

YES: Lube oil has had successful experience in engines operating above 85% load factor UNKNOWN: All documented experiences with the lube oil have been below 85% load factor EXPECTED: A field trial is in progress and the initial results are positive
Caterpillar cannot control base stock variations and lube oil additive packages at locations around the world and therefore takes no responsibility. Differences in load cycle, fuel quality, maintenance practices, and ambient conditions further prohibit a guarantee of lube oil performance at any installation. Past performance of a particular brand does not guarantee future results due to changes in formulation and regional differences. It is the responsibility of the oil producer to verify the consistency and quality level of the product.

14. Fuel Consumption Example
Generator set package is producing 17.5 bkWhr/U.S. gallon What is the engines brake specific fuel consumption (BSFC) in g/bKWhr? The fuel type is IF380 HFO with a Lower Heating Value (LHV) of 39 900 and a density of 8.3 lb/gal. Assume the generator to be 96.5% efficient.
To convert the IF380 fuel which has a heating value of 39 900 to a standard reference (i.e. distillate) LHV of 42 780 kJ/kg follow the procedure below:
LHVoriginal = 39 900 LHVnew = 42 780 BSFCnew = 207.6
g bkWhr
BSFCnew = 193.6
g bkWhr

15. Fuel Consumption Comparison ASSUMPTIONS
Assume the Caterpillar fuel consumption is 190 g/bkWhr without pumps, for a distillate 3616 engine at 1000 rpm CSR rating. This is based on ISO 3046 standard conditions of 100 kPa and 25 C and a fuel having a Lower Heating Value (LHV) of 42,780 kJ/kg. Assume that the competitors fuel consumption is 200 g/bkWhr with pumps, for a comparable engine rating, based on ISO 3046 standard conditions of 100 kPa and 25 C and a fuel having an LHV of 42,000 kJ/kg. Contact the manufacturer for the exact pump power consumption. We will assume the fuel consumption will decrease by 3% due to pump power losses.

COMPARISON
To make a comparison between the two fuel consumption values equal, it is necessary to base it on the same assumptions. We need to make the lower heating values the same and make both fuel consumptions based on having no pumps.
CALCULATIONS MISCELLANEOUS
15. Fuel Consumption Comparison, cont.
The Caterpillar brake specific fuel consumption (BSFC) is based on an LHV of 42,780 kJ/kg. Referring to example 13 on the previous page, we can convert the heating value to 42,000 kJ/kg by:
BSFC = 190
g bkWhr
(
X
) ) = 193.5
g bkWhr
BSFC = 190
g bkWhr
The competitors fuel consumption is calculated with pumps. To calculate the fuel consumption without pumps, use the following:
BSFC without pumps = BSFC with pumps - [(BSFC with pumps)*(% pump power losses)] BSFC without pumps = 200 g/bkWhr - (200 g/bkWhr)*(0.03) = 194 g/bkWhr
The Caterpillar BSFC is lower than the competitors.
