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:

2) Sytem 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 burnt the soot filtered in the CDPF, the control
system should be installed to check the operating range and increase the temperature o
f
exhaust gas by controlling the amount of fuel supplied and and intake air.
Two temperature sensors and one differential pressure sensor monitor the CDPF's operating
range. According to theses sensors' information, the throttle flap decreases the intake ai
r
entered to the throttle body. Also, the fuel injection pattern is added to increase the temperature
of exhaust gas for soot combustion.
There are two fuel injection patterns (pilot 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

When the engine is running in low load range, the amount of post injection and the amount of
intake air are controlled.
It is to raise the temperature by increasing the amount of fuel while decreasing the amount of
intake air.

4) Throttle Body for Different Engines
The throttle body is not installed in the D27DT engine (general), but is installed in the following
engines:
1) D27DT (EU IV) engine
2) D27DTP (POWER UP) engine
3) D27DTP (POWER UP) engine + CDPF
Both engines are equipeed with the throttle body, but its appearance and the related control
system are differ.

6) CDPF Over Load (Notice of Beginning CPF Regeneration Mode
- P1430)
The CDPF system enters the regeneration mode when the mileage is around 600 ~ 1,200
km, depending on the driving condition and driving habits. At this moment, the ECU
performs the CDPF regeneration process; however, the driver may not notice anything
because there is no engine warning or other signals indicating such process.
The control logic in the regeneration process is to increase the exhaust gas temperature by
increasing the fuel injection during post injection process and controlling the intake ai
r
amount(throttle body), and no significant change can be noticed in the vehicle condition.
The engine CHECK lamp flashes but there is no decrease in engine torque.
The engine CHECK lamp flashes to inform the driver when there is an over load due to soot
accumulation because the regeneration temperature cannot be reached due to low speed,
even though CDPF regeneration is in process.
The CDPF regeneration process must be completed by driving for 15-20 minutes at a speed
higher than 80 km/h to solve this problem.
The engine CHECK lamp flashes when CDPF is over loaded; therefore, 4) above must be
performed in this case. 1.

7) CDPF's Excessive Soot Accumulation (P0432)
When the vehicle is driven at a low speed (5-10 km/h) for a long time or long distance, the
soot over accumulates inside the CDPF and the combustion temperature cannot be reached
even by performing the soot combustion process. In this case, this DTC is generated.
This is more serious situation than the CDPF over load condition. Therefore, the engine
power is decreased to protect the system and the engine CHECK lamp is turned on.
Blow the soot between the engine and the exhaust system several times and clear the DTC
to solve this problem. If the same DTC is generated again, check the system according to
the DTC description related to the differential pressure sensor.
* This DTC is actually generated mostly due to the related system malfunction, such as
differential pressure sensor malfunction. 1.

(3) Speed Sensitive INT (Intermittent) Wiper
For STICS without rain sensor, perform the following operation:
1. Controls the wiper intermittent operation by the values from vehicle speed and volume.
Calculates and converts the Intermittent interval automatically by using the vehicle speed
and INT VOLUME when the ignition switch is in “ON” position and the INT switch is in
“ON” position (the engine is running).
The wipers are operated in vehicle speed sensitive mode when turning the INT switch
to “ON” position with the engine running or starting the engine with the INT switch
positioned “ON”.
Intermittent interval (at 0 km/h): 3 ± 0.5 ~ 19 ± 2 seconds -

-
2. Vehicle speed calculation
[Input the vehicle speed]
It is calculated by the numbers of input pulses for one second.
1 [pulses/sec] = 60 [km/h] x 60 [sec] / 637 pulses = 1.41 [km/h]
3. VOLUME calculation
Calculates the INT VOLUME with 5 grades as shown in the table in next page. -
4. Pause time calculation
Pause time: the duration that wipers are stopped at parking position
Elapsed time: the duration after the wiper motor started to operate from parking position
The pause time is calculated by the vehicle speed and VOLUME value as shown in the
table in next page. -
-
-
If the pause time is below 1.0 second, the wipers operate without pause.
If the pause time is over 1.5 seconds, the wipers operate intermittently. ·
