5. OPERATING PROCESS
[Configuration and principle of operation]
The exhaust gas
passed through the
exhaust manifold
enters into the CDPF
assembly (at approx
250℃).
Oxidation (DOC)
When the exhaust gas enters
into the CDPF assembly, its
CO, HC and PM are reduced
by the redox reaction of the
DOC. The remaining PM is
filtered and collected in
CDPF, and the temperature of
the exhaust gas is increased
to between 450 and 500°C.
Collecting PM
→ Regeneration
The engine ECU detects the
amount of PM collected by
the information from the
temperature sensors and
differential pressure sensor.
When the soot is
accumulated, the engine ECU
performs post-injection to
increase the exhaust gas
temperature and burns the
collected PM at approx.
600°C.
