166 Mack, Emissions Solution
A Diesel Particulate Filter (DPF) takes the place of the standard muffler. The DPF
is used to meet EPA requirements to help reduce soot and particulate emissions
into the atmosphere. The particulates are removed by collecting in the DPF unit,
where they are eventually oxidized with passive regeneration or active regeneration
of the filter. The electrical system and exhaust aftertreatment system of the vehicle
will determine when regeneration is required. Mack Trucks, uses conventional
exhaust aftertreatment system.
Conventional exhaust aftertreatment systems use passive-active regeneration. The
passive regeneration process oxidizes the particulates captured in the DPF while
the vehicle is in operation. An oxidation catalyst raises the exhaust temperature
to approximately 500–625 °C (932–1157°F), the temperature at which a chemical
reaction takes place to oxidize the soot (active regeneration)
Depending on how the vehicle is set up, regeneration can occur while the vehicle is
being driven (referred to as a "moving" regeneration) or when the vehicle is parked
and idling (referred to as a "parked" regeneration).
CAUTION
When active regeneration occurs (with either system), the temperature of the exhaust
will be elevated. DO NOT park the vehicle with the exhaust outlet under low hanging
overhead flammable objects such as trees, awnings, etc., that could be damaged by
elevated exhaust temperatures. DO NOT remove the diffuser.
CAUTION
If the vehicle is in a location that may be hazardous when an active regeneration begins
(i.e., in close proximity to flammable materials or gases), the regeneration should be
stopped by pushing the DPF switch to the "Stop Regeneration" position.
If an active regeneration is stopped by the vehicle operator, it should be initiated at a
later time when the vehicle is in a safe location. However, if an active regeneration is
stopped repeatedly, the vehicle may need to be taken to a MACK service facility. The
service facility will use a service tool to manually initiate the regeneration.
