Knock Sensor

A knocking surge out of the tube arrest is sensed namely vibrational pressure with the aid of the Knock Sensor. This stress is transformed into a voltage signal yet sent in conformity with the Engine Control Module (ECM). The ECM utilizes the Knock Sensor signal in conformity with rule the of timing.

Engine knock happens within a unique frequency range. The Knock Sensor, positioned among the machine block, barrel head, or consumption various is tuned in imitation of becoming aware of so frequency.

Inside the dander, the sensor is a piezoelectric element. Piezoelectric elements cause a voltage so stress then surge is applied after them. The piezoelectric thing between the Knock Sensor is tuned according to the device's bang frequency.

The surge from the engine knocking vibrates the piezoelectric component generating a voltage. The voltage yield from the Knock Sensor is best at that time.
