SENSORS AND ACTUATORS DETAILS

1. CRANK ANGLE SENSOR

The crank angle sensor is a magnetic field sensitive

transducer and generates a voltage output propor-

tional to the rate of change of the magnetic field

near a "Missing tooth" configuration. It monitors the

rotating speed (

rpm

), the position of crankshaft/ pis-

ton and speed fluctuations of the engine and gives

continuous feedback to the ECU. In other words, it

gives engine speed and piston position signal to the

ECU. The sensor gap should be 0.3 to 1.7 mm. If

the gap between the flywheel and crank angle sen-

sor is not correct, the engine will not start or may

misfire.

Intended Target wheel is uniformly cut with 60 teeth

and 2 teeth removed ideally between 120 & 90 de-

grees BTDC i.e. in a region where it is unlikely

Injection events shall be scheduled. The sensor will

measure a rotating feature (

target wheel

) by sens-

ing teeth/slot patterns and process this information

into a positive going voltage, zero crossing and

negative going voltage pulse for each tooth/slot that

passes below the sensor tip.

LOCATION

The crank angle sensor is fitted on the clutch hous-

ing.
