254 Mack, EPA2010 Emissions Solution
CAUTION
If the vehicle is in a location that may be hazardous when DPF Regeneration
begins (i.e., in close proximity to flammable materials or gases, inside tunnels,
parked under flammable objects, etc.), the DPF Regeneration should be stopped
(if equipped). If DPF Regeneration is stopped by the vehicle operator, it must be
initiated at a later time when the vehicle is in a safer location. DPF Regenerations
that are stopped and never restarted at a later time, however, will require that the
vehicle be taken to an authorized Mack Truck dealer to have the Aftertreatment
Regeneration manually started with special service tools.
Note:
During vehicle operation, idle speed may increase when the vehicle is stopped
at a traffic light to maintain heat in the DPF for passive regeneration and urea dosing.
There are two types of Aftertreatment DPF Regeneration: Passive regeneration and
Parked regeneration.
Passive regeneration occurs when the exhaust gas within the aftertreatment system
is hot enough to remove soot without injecting additional fuel into the dpf system.
On chassis equipped with a US07 aftertreatment system, DPFs needed an active
regeneration, that included this injection of fuel. With the addition of the SCR system
active regenerations are no longer needed for EPA2010.
Parked Regeneration
The Aftertreatment DPF Regeneration system is self-monitoring. Under certain duty
cycles driver action is needed to perform a parked regeneration. When driver action is
needed to perform a parked regeneration, an icon at the top of the DPF Smart switch
will illuminate to notify the vehicle operator. The DPF Smart switch allows the
vehicle operator to either stop or start regeneration. (Certain conditions must be met,
however, before regeneration can be manually started.)
Parked regeneration allows the operator to start and/or stop the regeneration
manually when the vehicle is parked and the engine is idling. The operator is
notified that a regeneration is needed when the icons on the DPF Smart switch
illuminate. The operator should perform the regeneration as soon as possible.
Please refer to the instructions below on how to use the DPF Smart switch for
parked regenerations.
1. Move the vehicle to a safe location, apply the park brake and allow the
engine to idle.
