Diesel Particulate Filter (Dpf) - PREVOST H3-41 Maintenance Manual

SECTION 04 : EXHAUST AND AFTERTREATMENT

3. DIESEL PARTICULATE FILTER (DPF)

Besides trapping soot,
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 most vehicle applications and duty
cycle, this will occur after approximately 200,000
to 400,000 miles (320,000 to 640,000 km) of
operation.
WARNING
