FUNCTION AND OPERATION PRINCIPLE

Piston position on combustion chamber is the substantial
to define the starting of injection timing. All engine pistons
are connected to crankshaft by connecting rod. Sensor
on crankshaft can supply the informations concerning all
piston positions, revolution speed is defined by revolution
perminute of crankshaft. Prior input variable is determined
at ECM by using signal induced from crankshaft position
sensor.

SIGNAL WAVEFORM

Fig.2

Fig.1) This shows waveform of Crank Shaft Position Sensor and Cam Shaft Position Sensor simulatneously. The middle area
          indicates reference points of Crank Shaft Position Sensor and Cam Shaft Position Sensor. 

Fig.2) Crank Shaft Position Sensor and Cam Shaft Position Sensor signal are measured simultaneously.  
          Cam Shaft Position Sensor 
          signal is outputted once when Crank Shaft Position sensor signal is outputted twice. LOW and HIGH output of Cam Shaft 
          Position sensor reference point is detected at Crank Shaft Position sensor reference point.
          ( Injection sequence is determined based on LOW and HIGH signal of Cam Shaft Position Sensor reference point as 
            detecting cylinder position.)

FUNCTION AND OPERATION PRINCIPLE

On electronic injection systems, there is no longer a load
lever that mechanically controls the fuelling. The flow is
caculated by the ECM depending on a number of param-
eters, including pedal position, which is measured using
a potentiometer. The pedal sensor has two potentio-me-
ters whoses slides are mechanically solid. The two po-
tentiometers are supplied from distinct and different power
sources so there is built in redundancy of information giv-
ing reliable driver’s request information. A voltage is gen-
erated across the potentiometer in the acceleration posi-
tion sensor as a function of the accelerator-pedal setting.

Using a peogrammed characteristic curve, the pedal’s po-
sition is then calculated from this voltage.
