Description and operation
Knocking
is a phenomenon characterized by undesirable vibration and noise that
can cause engine damage. Installed on the cylinder block, Knock Sensor
(KS) senses engine knocking.
When
knocking occurs, the vibration from the cylinder block is applied as
pressure to the piezoelectric element. When knocking occurs, the sensor
produces voltage signal. The ECM retards the ignition timing when
knocking occurs. If the knocking disappears after retarding the ignition
timing, the ECM will advance the ignition timing. This sequential
control can improve engine power, torque and fuel economy.
