2. CDPF(EURO IV) SYSTEM
The CDPF system is only installed to the D27DT engine, and the major changes comparing to the
previous D27DT engine is as follows:
CDPF (Catalyst & Diesel Particulate Filter) and sensors
Under air cleaner in righ
side of engine
compartment
As the soot is filtered in the CDPF, the pressure between the front side and the rear side of the
filter is different from each other. If the amount of soot is over 28 g, the soot is burnt in the
CDPF. The combustion is determined depending on the pressure difference, temperature of
exhaust gas and EGR ratio. According to these, the soot filtered by post injection of injector is
burnt at
CDPF Exhaust Gas Temperature Sensor
The two temperature
sensors inside the CDPF
are installed in exhaust
manifold (front exhaust
gas temperature sensor)
and in DOC (rear exhaust
gas temperature sensor),
and perform the following
functions.
Front Exhaust Gas Temperatur
e
Sensor:
Rear Exhaust Gas
Temperature Sensor:
Measures the exhaust gas
temperature of the exhaust manifold.
As it is installed in front of the VGT
turbocharger, it also monitors the
exhaust gas temperature coming to
the turbocharger. If the temperature of
the exhaust gas flowing to the
turbocharger is higher than the
specification, the engine lowers the
exhaust gas temperature.
Measures the increased
exhaust gas temperature
after the oxidation process
of DOC. If the temperature
injection amount is
increased to increase the
temperature.
