Electronic Engi ne Features
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 diagnostics
•
Aftertreatment Regeneration
