ENGINE FUEL SYSTEM
OVERVIEW AND OPERATION PROCESS
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 fo
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 MDP
(minumum current for the solenoid in the
injector to lift the nozzle) is leaned only
when the engine is running. However, fo
the D27DTP engine, it is learned when
the vehicle is in motion and the engine is
at idle speed.
