Engine Specifications
Note: The front end of the engine is opposite the flywheel end of the engine. The left side and the right side of the engine are determined from the flywheel end. The number 1 cylinder is the front cylinder.C32 Marine Engines

Rotation (flywheel end) Counterclockwise Electronic Engine Features
These Caterpillar Marine Engines are designed with electronic controls. The integral on board computer controls the operation of the engine. Current operating conditions are monitored. The Electronic Control Module (ECM) controls the response of the engine to these conditions and to the demands of the operator. These conditions and operator demands determine the precise control of fuel injection by the ECM. The electronic engine control system provides the following features:
Engine monitoring
Electronic engine speed governing
Automatic air/fuel ratio control
Torque rise shaping
Injection timing control
System diagnosticsFor more information on electronic engine features, refer to the Operation and Maintenance Manual, "Features and Controls" topic (Operation Section).Engine Cooling and Lubrication
The cooling system consists of the following components:
Centrifugal jacket water pump that is driven by gears
Two water temperature regulators which regulate the engine coolant temperature
Oil cooler
Auxiliary water pump or an SCAC water pump
Deaerators that remove air from the coolant
Raw/sea water aftercoolingThe engine lubricating oil that is supplied by a gear-type pump is cooled. The engine lubricating oil is also filtered. Bypass valves provide unrestricted flow of lubrication oil to the engine components during the following conditions:
High oil viscosity
Plugged oil cooler or plugged oil filter elements (paper cartridge)Marine Transmissions
Several manufacturers of marine gears offer marine transmissions through local distributors. Lubrication oil for the marine transmission can be cooled by an optional engine mounted transmission oil cooler (certain engine ratings).Engine Service Life
Engine efficiency and maximum utilization of engine performance depend on the adherence to proper application guidelines and operation and maintenance recommendations. In addition, use recommended fuels, coolants and lubricants. Use this Operation and Maintenance Manual as a guide for required engine maintenance.Expected engine life is generally predicted by the average power that is demanded. The average power that is demanded is based on fuel consumption of the engine over a period of time. Reduced hours of operation at full throttle and/or operating at reduced throttle settings result in a lower average power demand. Reduced hours of operation will increase the length of operating time before an engine overhaul is required. For more information, refer to the Operation and Maintenance Manual, "Overhaul Considerations" topic (Maintenance Section).
