C32 Marine Engine Specifications
Cylinders and arrangement 12 cylinder vee block
Bore 145 mm (5.7 inch)
Stroke 162 mm (6.4 inch)
Compression ratio 15:1
Aspiration Twin turbocharged aftercooled aspiration
Displacement 32 L (1953 in3)
Firing order 1-10-9-6-5-12-11-4-3-8-7-2
Rotation (flywheel end) Counterclockwise Electronic Engine Features
The engine has built-in diagnostics in order to ensure that all of the components are operating properly. In the event of a system component failure, the operator will be alerted via the diagnostic lamp located on the control panel. Caterpillar Electronic Technician (ET) can be used to read the numerical code of the faulty component or condition. Intermittent faults are also logged and stored in memory.The Cat Marine Engine is 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 diagnosticsThe engine ECM will automatically provide the correct amount of fuel in order to start the engine. Do not hold the throttle down while the engine is cranking. If the engine fails to start in20 seconds, release the starting switch. Allow the starting motor to cool for 2 minutes before using the starting motor again.For more information on electronic engine features, refer to the Operation and Maintenance Manual, "Features and Controls" topic (Operation Section).Engine Cooling and Lubrication
The engines have water-cooled exhaust manifolds, risers, and turbochargers. These components will minimize the heat that is radiated into the engine room. Changes to the cooling system of these engines minimize the weight and the size of the engine. These changes also improve the engine performance. The heat exchanger, expansion tank, and deaerator help prevent cavitation of the water pump which helps to maintain the performance of the jacket water pump.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
Deaerators that remove air from the coolant
Raw/sea water aftercoolingThe engine lubricating oil, which 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
