2.CDPF (EURO 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
The rear 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.
Front exhaust gas temperature sensor
(Measuring temperature of exhaust gas in
exhaust manifold)
Rear exhaust gas temperature sensor
(Measuring temperature of exhaust gas
escaping DOC)
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
so that the soot is burnt. The soot is burnt for
15 ~ 20 minutes. -

2) System Composition for Soot Combustion
When the engine is running in low load range, the temperature of exhaust gas is decreased as the
amount of fuel supplied is decreased. To burn the soot filtered in the CDPF, the control system should
be installed to check the operating range and increase the temperature of exhaust gas by controlling the
amount of fuel supplied and intake air.
Two temperature sensors and one differential pressure sensor monitor the CDPF's operating range.
According to these sensors' information, the throttle flap decreases the intake air entered to the throttle
body. Also, the fuel injection pattern is added to increase the temperature of exhaust gas for soot
combustion.
There are three fuel injection patterns (pilot injection, pre-injection and main injection). As the CDPF is
installed, the post injection pattern is added.
3) Post Injection and Air Mass Control
When the differential pressure sensor detects the pressure difference between the front and the rear
side of CDPF, the sensor sends signal indicating the soot is acumulated and the post injection is
performed to raise the temperature of exhaust gas. The amount of fuel injected is determined according
to the temperature of exhaust gas detected by the rear temperature sensor. If the temperature is below
the amount of fuel injected is increased to raise the temperature. If the temperature is over
the amount of fuel injected is decreased or not controlled.
When the engine is running in low load range, the amount of post injection and the amount of intake ai
r
are controlled. It is to raise the temperature by increasing the amount of fuel while decreasing the
amount of intake air.
