2.CDPF (EU-IV) SYSTEM CONTROL
1) General Description
As the soot is filtered in the CDPF, it is burnt and removed, and the CDPF is returned to the
initial state to collect the soot. Therefore, the burning procedures in the CDPF can be called as
regeneration.
The CDPF assembly is integrated with DOC (at front side) and DPF (at rear side).
The DPF burns the soot with high-temperature exhaust gas (over 600°C).
exhaust gas temperature sensor monitors the temperature of DPF section. If this temperature is
below the regeneration temperature, the ECU increases the post injection period to increase the
fuel injection amount, and consequently to increase the exhaust gas temperature.
- Normally, when the vehicle is driven for 600 ~ 1,200 km, the enough amount of soot to be
burnt is filtered and accumulated in the CDPF. The ECU increase the amount of post
injection to increase the tempeature of exhaust gas up to 600°C
burnt. The soot is burnt for 15 ~ 20 minutes.
