The Caterpillar C9.3 Engine is designed for 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 speed governor
Automatic air/fuel ratio control
Torque rise shaping
Injection timing control
System diagnostics
Aftertreatment regeneration control
NOX reduction system controlAdditional Features
The following additional features provide increased engine fuel economy and serviceability:
Cold starting capability
Tampering detection
DiagnosticsCommon Rail Fuel Injection System
The common rail fuel injection system performs the following functions:
Pump the fuel.
Meter the fuel.
Time the fuel injection.The fuel pump pressurizes the fuel. The fuel pump pumps the fuel to the common fuel rail. The common rail fuel injectors inject the fuel into the cylinders at a precise time. The fu
