ENGINE 167 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 rotat- ing speed ( rpm ), the position of crankshaft/ piston and speed fluctuations of the engine and gives con- tinuous 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 sensor 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 sensing teeth/slot patterns and process this information into a positive going voltage, zero crossing and negative going voltage pulse for each teeth/slot that passes below the sensor tip. LOCATION The crank angle sensor is fitted on the clutch hous- ing.
