EDGE-CUTTING 7T6936 - Caterpillar

The electronic control system includes the following major components:
Detonation sensors
Electronic control module (ECM)
Engine speed/timing sensor
Integrated sensing module (ISM)
Flash file (software)
Fuel control valve
Pressure sensors
Temperature sensors
Wiring harnessThe electronic control system operates integrally with the engine fuel system in order to control the fuel delivery and the injection timing. The ECM provides increased control of timing in comparison to the conventional mechanical engine. Injection timing is achieved by precise control of the injector firing time. The engine speed is controlled by adjusting the firing duration. The ECM energizes the fuel injector solenoids in order to start injection of fuel. Refer to Systems Operation, "Fuel System Operation" for a complete explanation of the fuel injection process.
