SECTION 4 – ENG INE OPERATION
Operation (cont.)
AFTERTREATMENT SYSTEM
The engine and vehicle exhaust piping includes an
Aftertreatment System to capture soot and other particulates
before they exit the exhaust pipe. The s oot is captured by the
Diesel Particulate Filter (DPF) and is periodically converted to
carbon dioxide (CO
2
) by a Regeneration (Regen) process.
The Regen process may take place during vehicle operation
(Active Regen). The Active Regen process will be triggered by
either a time-based soot or a soot mass buildup-based strategy.
A P arked Regen process is required when insufficient therm al
energy has not been present to initiate the process for Diesel
Oxidation Catalyst (DOC) light off. The vehicle is required to be
parked (stationary).
• A Parked Regeneration will be requested if the Passive
Regeneration cannot be completed during driving.
• In this case, a lamp will be lit to alert the operator to perform
a Parked Regeneration.
• The operator must park the vehicle and then perform the
Regen as required.
• Follow the Parked Regeneration process listed in the Vehicle
Operator Manual.
• If the Parked Regeneration process is ignored, the engine
may stop running.
• See th e “Safety Information” (page 3) se ction for safety
precautions.
A Prelimin a ry Diesel Oxidation C ataly st (PDOC) and a DOC
operates together to oxidize the injected fuel to increase the
exhaust gas temperature as needed for D PF Regen.
ENGINE IDLE SHUTDOWN TIMER (FEDERAL-OPTIONAL)
GOVERNMENT REGULATION: State and local
regulations may limit engine idle time. The vehicle
owner or operator is responsible for compliance with
these regulations.
The optional Idle Shutdown Timer (IST) allows the Engine
Control Module (ECM) to shutdown the engine during extended
idle. Id le time can be programmed from 5 to 120 min utes. The
ECM can be programm ed to deactiv at e the IST when the Power
Takeoff (PTO) is active.
Thirty seconds before engine shutdown, the IDLE SHUTDOWN
indicator illuminates. This con tinues until the e n gine shuts dow n
or the low idle shutdown timer is reset. The engine must be out of
gear for the IST to work. Engine shutdown timer will deactivate
for one or more of the following conditions:
• Engine speed is not at idle speed (700 rpm).
