EMISSION SOLUTION AND CONTROL
AFTERTREATMENT, MACK
NOTE
If passive regeneration occurs during
vehicle operation, idle speed may increase
when the vehicle is stopped at a trafc
light to maintain proper Regeneration
conditions.
There are two types of aftertreatment
DPF regeneration: Passive regeneration
and Parked or 'Active' regeneration.
Passive regeneration occurs when the
exhaust gas within the aftertreatment
system is hot enough to burn soot
without injecting additional fuel into the
DPF system. On chassis equipped with
a US07 aftertreatment system, DPF”s
required an active regeneration, that
includes this injection of fuel.
Parked or 'Active' regeneration is
initiated manually by the driver when
alerted by the DID. The vehicle must be
stationary to begin the regeneration, and
remain stationary to complete.
The Aftertreatment DPF Regeneration
system is self-monitoring. When the
aftertreatment Diesel Particulate Filter is
full, aftertreatment DPF regeneration is
needed. The Aftertreatment DPF
Regeneration Needed icon illuminates in
the instrument cluster. Also, the "Parked
REGEN Needed" message is displayed.
