2. CDPF (EURO IV) SYSTEM CONTROL
1) Combustion Temperature and Procedures
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. -

Do not allow the fluid and engine oil to make contact with the body paintwork and hoses.
If work on the fluid system such as fuel and oil, working area should be well ventilated and
smoking should be prohibited.
Gasket or seal on the fuel/lubrication system should be replaced with new ones and bolts and
nuts should be tightened as specified.
After removal/installation works, be sure to check whether there is leak on the connecting
section. -

If fine dust or foreign material enters into DI engine's fuel system, there can be serious
damages between HP pump and injectors. So, be sure to cover removed fuel system
components with cap and protect removed parts not to be contaminated with dirt. (Refer to
cleanness in this manual while working on DI engine fuel system)
When working on the fuel line between priming pump and injector (including return line),
always plug the openings with caps to prevent foreign materials or dust from entering to the
openings and connections.
The HP fuel supply pipe (HP pump to fuel rail) and HP fuel pipe (Fuel rail to injector) should
be replaced with new ones when removed. 1.

Electric devices should be handled more carefully.
Currently, the engine has a lot of electric devices. There could be poor engine performance,
incomplete combustion and other abnormal symptoms due to short circuit or poor contact.
Before work on engine and electrical equipment, be sure to disconnect battery negative (-)
terminal.
When replacing the electric device, use only genuine part and check the conditions of
connections and grounds. Loosened connection or ground makes cause a fire and personal
injury. -
