1. INTAKE SYSTEM LAYOUT
The intake system for the D27DTP (POWER UP) engine is equipped with the throttle body that
has a flap to block the air coming to the engine when the engine is switched off. Therefore, the
structure of the intake manifold has been changed.
Also, the improved HFM sensor (from HFM5.0 to HFM6.0) has been installed to control the
intake air precisely so that the NOx in the exhaust gas can be decreased.

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:

1. OVERVIEW
As the solution for environmental regulations and PM Particla Material) of diesel engine, the low
emission vehicle is getting popular. This vehicle is equipped with an extra filter to collect the
soot and burn it again so that the amount of PM in the exhaust gas passed through the DOC
(Diesel Oxydation Catalyst) is reduced. The CDPF (Catalyst & Diesel Particulate Filter) is an
integrated filter including DOC (Diesel Oxydation Catalyst) and DPF (Diesel Particulate Filter).
▶COMPARISON OF THROTTLE BODY FUNCTIONS BASED ON EXHAUST EMISSION
REGULATION
Regulated parts are carbon monoxide (CO), nitrogen oxide (NOx), particular matter (PM) and
soot in the exhaust emission, and the particulars of the regulations are prescribed in the
following table.

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.
