The exhaust gases pass through the DOC to remove
contaminants, carbon monoxide, and hydrocarbons.
The exhaust gases then enter the DPF where any
particulate matter soot and ash will be trapped.
The CEM uses a passive and active regeneration
process to ensure that normal operation of the
engine removes the soot. The soot is removed at an
equal rate of which the soot is captured. The ash
remains in the DPF.
Electronic Engine 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
• Injection timing control
• System diagnostics
Engine Diagnostics
The engine has built-in diagnostics to ensure that the
engine systems are functioning correctly. The
operator will be alerted to the condition by a "Stop" or
"Warning" lamp. Under certain conditions, the engine
horsepower, the engine speed, and the vehicle
speed may be limited. The electronic service tool
may be used to display the diagnostic codes.
There are four types of diagnostic codes: Active
Diagnostic Code, Logged Diagnostic Code, Active
Event Code, and Logged Event Code.
The ECM provides an electronic governor that
controls the injector output to maintain the desired
engine RPM.
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 generally predicted by the
average power that is demanded. The average
power that is demanded is based on fuel
consumption of the engine over a period of time.
Reduced hours of operation at full throttle and/or
operating at reduced throttle settings result in a lower
average power demand.
The aftertreatment system can be expected to
function properly for the useful life of the engine
(emissions durability period), as defined by
regulation, subject to prescribed maintenance
requirements being followed.
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.
