Component Description
INJECTION TIMING CONTROL VALVE
The injection timing control valve is built into the fuel injection
pump. It controls the timer piston to change the fuel injection tim-
ing.
The timing control valve is a solenoid valve located in the line
between high-pressure chamber and low-pressure chamber. It
changes fuel pressure in the high-pressure chamber.
When current flows through the solenoid (the solenoid turns ON),
the timing control valve opens, advancing fuel injection timing.
When current does not flow through it, the timing control valve
closes, retarding injection timing.
The ECM emits an ON-OFF duty signal. The longer the OFF-
duration, the greater the advance angle. The longer the
ON-duration, the greater the retard angle. This means that chang-
ing the ON-OFF duty ratio makes it possible to achieve an optimal
advance angle and accurately control fuel injection timing.

Component Description
CRANKSHAFT POSITION SENSOR (TDC)
The crankshaft position sensor (TDC) monitors engine speed by
means of signals from the sensing plate (with four protrusions)
installed to the clutch housing. The datum signal output is detected
at ATDC 30É and sent to the ECM. The sensor signal is used for
fuel injection control and fuel injection timing control.

IPre-glow
When the ignition switch is turned on the ON position, the glow
indicator lamp will turn ON and pre-glow starts.
The glow relay is turned ON continuously. The ON time of both
the glow indicator lamp and the glow relay is determined by the
engine coolant temperature. Pre-glow ends when the pre-glow
time elapses or when the engine is started.
I Intermediate glow
Intermediate glow starts when the pre-glow time has elapsed
and the engine has not been started. The glow relay is turned
ON intermittently. Intermediate glow ends when the intermedi-
ate glow time has elapsed, or when the engine is started.
I After-glow
After-glow starts as soon as the engine is running and the
engine coolant temperature is below 50ÉC (122ÉF). The glow
relay is turned on continuously. After-glow ends when the after-
glow time elapses, or when the engine coolant temperature
exceeds 50ÉC (122ÉF).
