Crank Shaft Position Sensor & Cam Shaft Position Sensor
 
 
 
 

Sensitivity mode column Karnak ( Crank Shaft By Position Sensor CKP ):
The sensors intocolumnKarnak ( CKP ) and column camshafts ( the CMP ) in modern models exploringsubjectcolumnKarnak or camshafts directly to achievehigher level of accuracy. Although both information can be obtained from only one sensor, on most systems the additional signal from the camshaft position (CMP) sensor is used to distinguish the upper final mid-position of cylinders #1 and #4.        
 

 
 
 
 
Where the crankshaft position sensor (Fig. 1) takes the position of the crankshaft and sends a signal to the electronic control unit in the car, as according to the signal received from the crankshaft sensor, the electronic control unit calculates the injection timing, ignition timing and engine speed (Fig. 2).

There are three types of crankshaft sensors:
1-   Optical
type 2-    Inductive
type 3- Hall IC type
 

 
 
 
 
1. Type photogravure the Optical Tipo :
This type is used in the old engines placed where the distributor sparks (Alaasebratir) mail , where he works with Polychlorinated Light ( Photo diode ) depends on the issuance of a signal through the vision of incision ( Slit ) an existing disk distribution Balaasebratir a through which is determined The position of the crankshaft as the disc rotates.

2- The second and third types, one of them is used according to the type of engine, and both are placed on the crankshaft gear to sense the teeth of the gear, as they are used in engines that operate without a distributor (sputter), and in this case there is a sensor of the same type used to sense the position of the camshaft.
 

 
 
 
Important note: If the crankshaft position sensor fails, it will be impossible to start and crank the engine. Thus, it is one of the main reasons for not running the engine.
 
 
 
 
Sensitivity mode column Camshaft ( Cam Shaft By Position Sensor the CMP ):
a sensitive camshaft setting is of the same type of sensitive crankshaft where he selects a column mode camshafts and send a signal to the electronic control unit, which in turn highlight the final middle position of the upper cylinder No. 1 and No. 4 by comparing the sensor signal Position the crankshaft, in which case the cylinder into which the fuel will be injected is determined, as well as the ignition timing.
