INTAKE ENGINE OIL CONTROL VALVE
The intake engine oil control valve is installed on the left side of
the cylinder head. Receiving the duty signal from the ECM, the
intake engine oil control valve moves the spool valve position
and divides the oil pressure from the cylinder block into the
advanced chamber and the retarded chamber of the V.V.T.
sprocket as well as continually changes the intake camshaft
phase. The spring makes spool valve stop at the position
where the intake camshaft is at the most retarded angle when
the engine is stopped. The ECM moves the spool valve posi
-
tion by increasing and decreasing ON duty ratio of the intake
engine oil control valve and allows the intake camshaft to be at
the target phase angle. When the duty ratio increases, the
spool valve moves. The sprocket rotates toward the advanced
angle side. When the duty ratio decreases, the sprocket rotates
toward the retarded angle side. When the medium duty ratio, at
which the spool valve is at the medium position, is achieved, all
the oil passages are closed. This allows the phase angle to be
kept constant. The ECM changes and controls the duty ratio in
accordance with the engine operation to get the optimum
phase angle.

EXHAUST ENGINE OIL CONTROL VALVE
The exhaust engine oil control valve is installed on the right
side of the cylinder head. Receiving the duty signal from the
ECM, the exhaust engine oil control valve moves the spool
valve position and divides the oil pressure from the cylinder
block into the advanced chamber and the retarded chamber of
the V.V.T. sprocket as well as continually changes the exhaust
camshaft phase. The spring makes spool valve stop at the
position where the exhaust camshaft is at the most advanced
angle when the engine is stopped. The ECM moves the spool
valve position by increasing and decreasing ON duty ratio of
the exhaust engine oil control valve and allows the exhaust
camshaft to be at the target phase angle. When the duty ratio
increases, the spool valve moves. The sprocket rotates toward
the retarded angle side. When the duty ratio decreases, the
sprocket rotates toward the advanced angle side. When the
medium duty ratio, at which the spool valve is at the medium
position, is achieved, all the oil passages are closed. This
allows the phase angle to be kept constant. The ECM changes
and controls the duty ratio in accordance with the engine oper

ation to get the optimum phase angle.

When the ignition switch-IG "ON" signal is input,
ECM turns ON the power transistor for control of the
MFI relay. As a result, current flows through the MFI
relay's coil, the relay switch turns ON and power is
supplied to each sensor and actuator. Also, when
ignition switch-IG "OFF" signal is input, ECM per
-
forms the following controls and then turns OFF the
power transistor for control of MFI relay.

When current flows through the fuel pump relay, the
relay turns ON and the fuel pump is driven. The fuel
pump relay is built into the ETACS-ECU. When the
ignition switch-ST signal is input, ECM turns ON the
power transistor for control of the fuel pump relay. As a result, power is supplied to the fuel pump. Also, if
engine speed falls below a set value, the fuel pump
relay is turned OFF. Thus, it deals with sudden stop
-
pages such as engine stalling etc. by stopping the
pump.

GENERAL DESCRIPTION
ENGINE LUBRICATION12-2
GENERAL DESCRIPTIONM2120000100249
The lubrication system is a full-flow, filter pumping
system.
The engine oil that accumulates in the oil pan is
drawn and discharged by the oil pump. After its pres
-
sure is regulated by the relief valve, the oil passes
through the oil filter. Then, it flows from the oil pas
-
sage in the cylinder block to the individual crankshaft
journals and the cylinder head.
After the oil is pumped to the individual crankshaft
journals, it passes through a passage in the crank
-
shaft and is fed to the pins. After the oil is pumped to
the cylinder head, it flows to the camshaft journals
and the engine oil control valves.

SEAT BELT RETRACTOR WITH FORCE LIMITER
.The driver’s/front passenger’s seat belt retractor has been
equipped with a force limiter. The force limiter is a device which
operates when a predetermined force is applied, and limits the
force.
.
OPERATION
1. If a collision energy is transmi tted to the seat belt, the ELR
mechanism will operate to lock the seat belt.
2. If the energy increases to a predetermined value, the torsion bar will be distorted. As the spindle rotates together with the
torsion bar, the seat belt w ebbing is pulled out, reducing the
impact to the occupants.
