  • The knock sensor functions according to the piezoelectric principle in which the enclosed piezoceramic element converts any vibration occurrring in the engine into electrical voltage signals by means of its own deformation. The voltage signals form the basis for correcting the current "knock firing point" for the control unit. The magnitude of these voltage signals (max. 3-4 V) depends on the intensity of the vibrations in the engine which are dictated by the regularity or irregularity of the combustion process.

    Knock sensor function?

    Maybe this question is already on here, I couldn't find it. This relates to my first question a couple days ago... What the hell is the function of a knock sensor, anyway?
