>>C<< FUEL HIGH-PRESSURE HOSE
INSTALLATION
Be careful not to allow any engine oil to enter the fuel
rail.
Be careful not to bend the fuel high-pressure hose as it
is made of plastics.
1. When connecting the fuel high-pressure hose to the fuel rail,
apply a small amount of new engine oil to the O-ring and
then insert the fuel high-pressure hose, being careful not to
damage the O-ring.
2. While turning the fuel high-pressure hose to the left and
right, install it to the fuel rail.
3. Check that the injector turns smoothly. If it does not turn
smoothly, the O-ring may be trapped. Remove the fuel
high-pressure hose and then re-insert it into the fuel rail and
check again.
INSPECTIONM1151003100672
Check the following points; replace the part if a problem is
found.
.
Intake Manifold Check
1. Check for damage or cracking of any part.
2. Clogging of the negative pressure (vacuum) outlet port.
3. Using a straight edge and feeler gauge, check for distortion
of the cylinder head installation surface.
Standard value: 0.15 mm (0.006 inch) or less
Limit: 0.20 mm (0.008 inch)

CHARGING SYSTEM
GENERAL DESCRIPTIONM1161000100629
The charging system charges the battery with the
alternator output to keep the battery charged at a
constant level during varying electrical load.
OPERATION
Rotation of the excited field coil generates AC volt-
age in the stator.
This alternating current is rectified through diodes to
DC voltage having a waveform shown in the illustra-
tion above.
The average output voltage fluctuates slightly with
the alternator load condition.When the ignition switch is turned on, current flows in
the field coil and initial excitation of the field coil
occurs.
When the stator coil begins to generate power after
the engine is started, the field coil is excited by the
output current of the stator coil.
The alternator output voltage rises as the field cur-
rent increases and it falls as the field current
decreases. When the battery positive voltage
(alternator S terminal voltage) reaches a regulated
voltage of approximately 14.4 V, the field current is
cut off. When the battery positive voltage drops
below the regulated voltage, the voltage regulator
regulates the output voltage to a constant level by
controlling the field current.
In addition, when the field current is constant, the
alternator output voltage rises as the engine speed
increases.
