These Caterpillar Engines are designed for electronic controls. These engines have an integral on board computer that is called an Electronic Control Module (ECM). The ECM monitors current engine conditions and power requirements. The optimum engine response is calculated and instructions are sent to the engine control systems. The systems respond and the engine responds accordingly. Total engine control is realized through the control of the fuel system and the engine speed/timing system. The electronic engine control system provides the following features:
Engine monitoring
Engine speed governing
Control of the injection pressure
Cold start strategy
Automatic air/fuel ratio control
Torque rise shaping
Injection timing control
System diagnostics
Cooling fan controlFor more information on electronic engine features, refer to the Operation and Maintenance Manual, "Engine Features and Controls" topic (Operation Section).Engine Diagnostics
The engine has built-in diagnostics to ensure that the engine systems are functioning correctly. The operator will be alerted to the condition by a "Stop or Warning" lamp. Under certain conditions, the engine horsepower may be limited. The control module can be used to view diagnostic codes.There are three types of diagnostic codes: active, logged, and event.Most of the diagnostic codes are logged and stored in the ECM. For additional information, refer to the Troubleshooting Manual, Diagnostic Code Cross Reference topic.The ECM provides an electronic governor that controls the injector output to maintain the desired engine rpm.Engine Cooling and Lubrication
The cooling system consists of the following components:
Self-priming centrifugal type pump that is driven by gears
Water temperature regulators which regulate the engine coolant temperature
Engine oil cooler which is used to transfer excess heat from the engine oil to the cooling system
RadiatorThe engine lubricating oil is supplied by a high pressure oil pump. The engine lubricating oil is cooled and 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 the 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 time. Reduced hours of operation at full throttle and/or operating at reduced throttle settings result
