Knocking is a phenomenon characterized by undesirable
vibration and noise and can cause engine damage. Knock Sensor (KS) is
installed on the cylinder block and senses engine knocking.
When knocking occurs, the vibration from the cylinder block
is applied as pressure to the piezoelectric element. When a knock
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.
