•
The regeneration controlling DPF system col-
lects particulate matter (PM) in exhaust gases
with a ceramic filter located inside the muffler
and burns the PM on the filter utilizing the effect
of the front oxidation catalyst (continuous DPF
regeneration).
•
Continuous filter regeneration is impossible
under certain conditions such as low-speed driv-
ing. Under these conditions, the system auto-
matically raises the exhaust temperature to burn
the PM to regenerate the filter (automatic DPF
regeneration). However, even automatic DPF
regeneration is sometimes impossible if the
vehicle is repeatedly driven very slowly and the
engine is frequently started and stopped. The
DPF must then be regenerated by burning the
PM under manual control (parked DPF regener-
ation).
