D27DT
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

the D27DTP engine, it is learned when
