ADAPTER-STRAP-LH 3G4308 - Caterpillar

Intended Use
This Power Generator is intended for use in generating electrical power.Engine Description
Caterpillar C27 Generator Sets provide the following features:
Four-cycle
Direct fuel injection
Mechanical Electronic Unit Injector (MEUI)
Turbocharged
Air-To-Air Aftercooler (ATAAC)Electronic Engine Features
Caterpillar C27 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 and auxiliary monitoring
Engine speed governing
Cold start strategy
Automatic air/fuel ratio control
Torque rise shaping
Automatic altitude compensation
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:
Gear-driven centrifugal water pump
Water temperature regulators which regulate the engine coolant temperature
Gear-driven oil pump (gear type)
Oil coolerThe 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)Engine Service Life
Engine efficiency and maximum utilization of engine performance depend on the adherence to proper 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 predicted by the average power that is demanded. The average power that is demanded is based on fuel consumption of the engine over a time period. For more information, refer to the Operation and Maintenance Manual, "Overhaul Considerations" topic (Maintenance Section).Engine Specifications
Note: The front end of the engine is opposite the flywheel end of the engine. The left and the right sides of the engine are determined from the flywheel end. The number 1 cylinder is the most forward cylinder.
