3. DIESEL PARTICULATE FILTER (DPF)
Besides trapping soot, the DPF (Diesel
Particulate Filter) also traps the ash that has
been generated when additives in engine oil are
burned. However, unlike soot, ash cannot be
oxidized. The ash that accumulates in the filter
will eventually cause an increase in exhaust
back pressure. EMS will constantly monitor the
ash accumulation and forecast the approximate
time until DPF ash cleaning is required. This
allows you the opportunity to plan for the DPF
ash cleaning interval. If ash cleaning is not
performed proactively, and the back pressure
increases beyond the system limit, EMS will flag
the amber warning light on the telltale panel,
notifying the operator that an ash cleaning is
required. Clean remanufactured DPF cartridge
will be available through Prevost on an
exchange basis. For Commuter vehicle
applications and severe duty cycle, this will
occur after approximately 4500 hours of
operation.
WARNING
HOT SURFACES
Keep yourself clear of hot Aftertreatment
System surfaces, particularly during and after
active or stationary regeneration. Hot surfaces
can cause serious burns.
Make sure Aftertreatment System
components are cold before handling.
MAINTENANCE
