Lucas Knock Sensors

 

The Lucas range of knock sensors includes over 100 references, all manufactured to the highest standards to ensure maximum performance and economy through optimum combustion. All knock sensors are covered by the Lucas 3 year warranty.

 

What is a Knock Sensor?

 

The knock sensor acts like a microphone, transforming the vibrations caused by the sound waves from knocking into a voltage signal that can be read by the ECU. The ECU will analyze the sound from each cylinder and compare it to a reference noise based on the average noise level for a set period. If the sensor detects any noise exceeding the reference level, the ECU will identify it as knocking and begin to retard the ignition timing until the noise level returns to normal. This process happens continually to achieve optimum timing.
