Electronic Engine Features
The 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
Extra Features
The following extra features provide increased
engine fuel economy and serviceability:
• Cold starting capability
• Tampering detection
• Diagnostics
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.
