Crankshaft Angular Position Sensor

 

The crankshaft angular position sensor is required to determine the valve timing, spark timing, etc, the angular position of the piston w.r.t TDC & BDC is necessary. The crankshaft position is measured by non-contacting measurements that required magnetic or optic phenomena. Thus, one full engine cycle from intake through exhaust requires two complete revolutions of the crankshaft. The one complete engine cycle corresponds to the crankshaft angular position going from zero to 720 degrees.
 
Thus, during each cycle, it is important to measure the crankshaft position with reference to TDC for each cylinder. The crankshaft rotational speed is one-half that of the crankshaft, so the crankshaft angular position goes from zero to 360 degrees for one complete engine cycle.
 
The position is measured by a magnetic reluctance position sensor.

The position is determined directly by magnetic phenomena. The sensor consists of a permanent magnet with a coil of wire wound around it. The disk is mounted on the crankshaft and the disk has four tabs that pass between the pole pieces of the magnet. whenever the tab passes through the gap, the magnetic flux will changes. The reluctance of steel is less and the reluctance of the air is more. When the steel disk passes through the gap or between the poles the magnetic flux produce will be increased.
 
The wire-wound is connected to the signal processing circuit, which is further connected to the control circuit.

I hope this article may help you all a lot. Thank you for reading.
