The engine 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
Engine speed governing
Control of the injection pressure
Cold start strategy
Automatic air/fuel ratio control
Torque rise shaping
Injection timing control
System diagnosticsFor
