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
r
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
r
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 o
f
injected fuel volume. (It is also installed
on the connection of the high pressure
fuel supply line of the HP pump.)

HP pump and common rail are increased
according to the increased amount of fuel
injection.
Also, the engine ECU, HFM sensor and
EGR system are changed to control the
fuel injection volume and engine more
precisely.

CRUISE CONTROL SYSTEM
The cruise control system will be cancelled when the button on the side of the switch is pressed,
or when one of the following conditions is met:
Put the cruise control switch lever in the neutral position when not using the cruise control
system.When the brake pedal is depressed or ESP is activated.
When the vehicle speed is less than 34 km/h (21.13 mph).
When the parking brake is applied while driving.
When the clutch pedal is depressed for shifting (M/T only). 1.
2.
3.
4.
(1) Abnormal Cancellation of the Cruise Control
When the rapid deceleration or acceleration occurs.
When the cruise control lever is faulty.
When the brake switch is malfunctioning or has an open circuit. 1.
2.
3.
When the cruise control function is cancelled abnormally or intermittent problems occur, stop
the vehicle and turn off the ignition switch and remove the key to reset the system. After a while,
turn on the ignition switch again to operate the cruise control system.
Do not move the shift lever to Neutral position while driving with the cruise control turned
on. Otherwise, it may result in system malfunction or accidents.
Always be prepared to use the brake or accelerator pedal for safe driving while the cruise
control system is running.
The actual speed can be different from the set speed momentarily when driving on a uphill
or downhill. So, it is recommended to disable the cruise control function on a uphill or
downhill. hen driving on a steep hill use the engine brake and foot brake properly to protect
the vehicle system and for a safe driving.
Ensure that the braking distance is maintained and use the brake pedal if needed. -
