1792-01ENGINE EXHAUST SYSTEM
1. COMPONENTS
The components of the exhaust system for the D27DTP (POWER UP) engine have been
changed as follows:
1. E-EGR valve: Controlling the EGR valve electrically and sends the valve location signal to
ECU (vacuum modulator control has been deleted)
2. EGR cooler: Decreasing EGR gas (NOx) efficiently by cooling the EGR gas and let it flow
to the intake pipe
3. VGT turbocharger: Increase in capacity and performance compared to D27DTP & D20DT
engine
The EGR system has been changed to control NOx more efficiently and the VGT turbo charge
r
has been changed to increase the engine power. For more details, refer to the next description.
The exhaust system for D27DTP (POWER UP) engine is as follows:

3. MAJOR CHANGES
The CDPF system is only installed to the D27DT engine, and the major changes comparing to
the previous D27DT engine is as follows:
Engine ECUFuel Common Rail and Fuel Rail
(Between Common Rail and Injector)
The I.D and O.D of fuel rail has changed
from 2.4 mm/6.0 mm to 3.0 mm/6.35 mm.
Also, the damping orifice is installed to
prevent the fuel pulsation occured by fuel
pressure.
The engine ECU has been revised since
terminals have been added for front/rear
temperature sensors.
Its version is 3.2, but it is not compatible
with ECU without CDPF.

4. OPERATION PROCESS
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
recycling.
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). 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.
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

burnt. The soot is burnt for 15 ~ 20 minutes.

5) Operating Procedures of CDPF
The most efficient and practical technology for now is adopted to the diesel particulate filter
(DPF).
This system collects the soot from the diesel engine to the filter and burns the soot so that ove
r
than 95% of soot can be removed from the exhaust gas. However, the durability and the cost o
f
additional system remain as problems.
Firstly, the exhaust gas is passed through the DOC and its temperature is increased as it is
oxidized. The ECU detects the temperature change with two temperature sensors. The CO, HC
and partial particulate material are removed from the exhaust gas (this procedures are the
sames as the ones for the conventional DOC and no sensor is required).
After the exhaust gas is passed through the DOC and oxidized, most of the harmful material is
removed from the exhaust gas. However, to meet the environmental regulations in the future,
the soot is filtered and burnt again in DPF to decrease the particulate material further.
The filtered soot is burned whenever the vehicle is driven for 600 ~ 1200 km. The driving
distance can be differed depending on the vehicle’s driving conditions. The soot is
burnt for 15 ~ 20 minutes.
