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.
Expected engine life is predicted by the average
power that is demanded. The average power that is
demanded is based on fuel consumption of the
engine over a time. Reduced hours of operation at
full throttle and/or operating at reduced throttle
settings result in a lower average power demand.
Reduced hours of operation will increase the length
of operating time before an engine overhaul is
required. For more information, refer to the Operation
and Maintenance Manual, “Overhaul Considerations”
topic.
Operation of emergency engines is limited to
emergency operations and required maintenance
and testing.
Aftermarket Products and Perkins
Engines
Perkins does not warrant the quality or performance
of non-Perkins fluids and filters.
When auxiliary devices, accessories, or
consumables (filters, additives, catalysts) which are
made by other manufacturers are used on Perkins
products, the Perkins warranty is not affected simply
because of such use.
However, failures that result from the installation
or use of other manufacturers devices,
accessories, or consumables are NOT Perkins
defects. Therefore, the defects are NOT covered
under the Perkins warranty.
