Knock Sensor: Description and Operation
KNOCK SENSOR (KS) The
knock sensor is attached to the cylinder block and sense engine knocking conditions.
A knocking vibration from the cylinder block is applied as pressure to the piezoelectric element. This vibrational pressure is then converted into a voltage signal which is delivered as output. If engine knocking occurs, ignition timing is retarded to suppress it.
