valve body. It comprises an aluminum case and a bracket with a stainless steel in it. for the high sensitivity
of fuel injector and the the existence of external impurities being in the fuel system, it is necessary to use
the high-efficiency paper filter core.
4.1 water temperature sensor“WTS05”
During cold starting and engine warming, ECU enrich the mixture according to the signal (see figure
61) from the sensor. When engine is warmed enough for fan to reach the operation range, the enrichment is
zero.

Fig.170
Sensor is mounted on the cylinder block by a mounting bracket. When it detects the impulses produced
by the teeth (60—2) in the flywheel (see figure. 169), engine speed may be calculated accurately by the
signal impulses produced by the 58 teeth which are arranged equally with a interval of 6
°
.
The RPM sensor position in the flywheel (signal wheel) is on the surface of the twentieth tooth before
the top dead center of the cylinder 1, 4, the angle between it and the top dead center of cylinder 2, 3 is 80
°
,
on the opposite of the fiftieth teeth (tooth counting begins from the tooth-missed area), except for deciding
cylinder 1,4 and cylinder 2,3 TDC, the sensor signal (see figure. 170) is also used in the microprocessor
：
—— Control ignition (ignition advance and ignition delay)
—— Generate signal for the RPM counter
—— Detect two missed teeth to confirm the synchronous position every engine revolution
Without the signal or the corresponding synchronous signal (60—2 signals/revolution)
，
ECU cannot be
operated.
Timing
：
Rotate the engine pulley (2) to keep cylinder 1 and cylinder 4 at TDC, i.e. the mark on the pulley (2)
and the mark (3 and 4) on the timing wheel cover of engine must be matched (see figure. 171).
