Remarks
D27DT Engine
* Version up
- D27DT: HFM5-CI
(Analog signal)
- D27DTP: HFM6-ID
(Digital signal added)
HFM 6.0
Electric controlled E-EGR valve
* E-EGR valve:
ECU controls the EGR valve
directly without any media. It
provide more precise EGR
control by transmitting the
electric signal of EGR valve
operating position.
HFM 5.0
Vacuum modulator controlled
EGR valve
Vacuum modulator
* D27DTP (POWER UP) engine
uses electric ally controlled E-
EGR valve. Thus, the vacuum
modulator for controlling EGR
valve has been deleted.
Throttle body
EGR cooler
* To enhance EGR function,
coolant EGR cooler is adopted
to reduce the temperature of
exhaust gas into the intake
manifold.
VGT turbo charger control
EGR valve for vacuum
modulator
Vacuum modulator for controlling
turbo charger actuator
* Throttle body is for future
regulation requiring emission
reductions. Currently, it is
used to prevent the engine
from turning off with fluttering
noise at the moment the air to
intake manifold is blocked by
closed flap when the engine is
switched off.

* Reason of changes
- To satisfy the emission
regulation, E-EGR valve and
EGR cooler are adopted.
And the layout also has a
great difference from D27DT.
EGR system layout
Oil pan
* The vehicle with D27DTP
