MAJOR CHANGES IN FUEL SYSTEM OF D27DTP (POWER
UP) ENGINE 1.
There are some changes in the parts related to the fuel system due to the newly adopted
D27DTP (POWER UP) engine. The major changes are as follows. Refer to the next pages for
further details.
1) Injector
Two nozzle holes are added (currently 7)
to the tip of the injector to increase the
amount of fuel injection and to improve
injection efficiency according to the
increased engine power.
The existing C2I coding (16 digits) is
changed to C3I coding (20 digits) to
monitor fuel injection and follow the target
value.
For the D27DT engine, the injector MD
P
(minumum current for the solenoid in the
injector to lift the nozzle) is leaned only
when the engine is running. However, for
the D27DTP engine, it is learned when the
vehicle is in motion and the engine is at
idle speed.

2) Common Rail
The orifice is added to the connection to
the fuel pipe of the HP pump to prevent
the fuel pulsation by the fuel supply and
fuel cut according to the increase of
injected fuel volume. (It is also installed on
the connection of the high pressure fuel
supply line of the HP pump.)D27DTP & D27DT (EU IV)
