The Cat C13 and C15 Engines are designed for electronic controls. The integral on board computer controls the operation of the engine. Current operating conditions are monitored. The Engine 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 speed governor
Automatic air/fuel ratio control
Torque rise shaping
Injection timing control
System diagnosticsThe following programmable features are included in the electronic control:
Cruise control
Governing of the PTO
Vehicle speed limiter
Fast idleAdditional Features
The following additional features provide increased engine fuel economy and serviceability:
Cold starting capability
Tampering detection
Diagnostics
Idle shutdown timer
American Trucking Association (ATA) data link (SAE J1587)
Society of Automotive Engineers (SAE) data link (SAE J1939)Engine Diagnostics
The engine has built-in diagnostics in order to ensure that all of the components are functioning properly. In the event of a deviation from the programmed limits, the operator will be alerted to the condition by a "DIAGNOSTIC" lamp that is mounted on the dashboard. Under certain conditions, the engine horsepower and the vehicle speed may be limited. A Cat electronic service tool may be used to display the diagnostic code.There are four types of diagnostic codes: active, logged, event and critical event.Most of the diagnostic codes are logged and stored in the ECM. For additional information, refer to the Operation and Maintenance Manual, "Engine Diagnostics" topic (Operation Section).The ECM provides an electronic governor that controls the injector output in order to maintain the desired engine rpm. The functionality of electronic governor is similar to the Cat mechanical governor, but the electronic governor includes additional features.For more information on electronic engine features, refer to the Operation and Maintenance Manual, "Engine Features and Controls" topic (Operation Section).Engine Cooling and Lubrication
The cooling system consists of the following components:
Centrifugal pump that is driven by belts
Water temperature regulator which regulates the engine coolant temperature
Oil cooler and radiator which incorporates a shunt systemThe engine lubricating oil that is supplied 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)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
