each cylinder that is indicated on the upper portion
of injector.

10. Install cylinder head assembly.
Refer to “Cylinder Head” in this manual.
11. Fill with about 300cc of engine oil from the high
pressure oil pipe installation port of the oil rail using
an oil filler.
If assembled without filling the oil rail with oil, the
time for engine starting will be longer.
12. Immediately install high pressure oil pipe and
tighten to specified torque.
Torque: 80 Nꞏm (8.1 kgꞏm / 57.9 lb ft)
13. Install cylinder head noise insulator cover.
Refer to “Cylinder Head” in this manual.
14. Install intercooler assembly.
Refer to “Intercooler” in this manual.
15. Install air cleaner cover and air duct.
16. Use TECH2 to rewrite injector data to ECM.
For rewriting method refer to section “Data
Programming in Case of ECM Change” of section
6E 4JX1 engine driveability and emissions in this
manual.NOTE:
1) On completion of servicing, bleed air from the
engine inside fuel passage by means of the priming
pump. (The priming pump should be operated more
times than in the case of conventional engines.)
2) As air is in the oil rail, it takes more time to start the
engine. Rough idling may occur while the air is
being bled completely after engine start, but it does
not indicate trouble.
The air will be bled and normal engine status will be
reached while the vehicle is driven for about 5 km
or engine is operated for about 5 minutes at 1500 to
2000 rpm.
3) The injector spare part will be provided for group
number B1, B2 and B3 only.
Injector Grade code Programming
(Injector Change)
In case of an injector change, the injector grade code
(category number) must be programmed by Tech-2.
Programming Procedure
1. Connect the Tech-2 to the vehicle DLC.
2. Turn the starter switch to the “ON” position.
3. Select the “Diagnosis” from the Main menu.
4. Select the “Programming” from the Application
menu.

FUEL FILLER CAP
The fuel filler cap contains a vacuum valve. If a
negative pressure develops in the fuel tank, the
external valve of the fuel filler cap opens to allow the
fresh air to flow into the fuel tank through the vacuum
valve.
INSPECTION
Check the seal ring in the filler cap for presence of any
abnormality and for seal condition.
Replace the filler cap, if abnormal.Legend

CHARGING SYSTEM
GENERAL DESCRIPTION
GENERATOR
CHARGING CIRCUIT
The charging system is the IC integral regulator
charging system and its main components are
connected as shown in Figure.
The regulator is a solid state type and it is mounted
along with the brush holder assembly inside the
generator installed on the rear end cover.The generator does not require particular maintenance
such as voltage adjustment. The rectifier connected to
the stator coil has nine diodes to transform A.C. voltage
into D.C. voltage. This D.C. voltage is connected to the
output terminal of generator.
