Product Name: Engine Dual Knock Sensors Wire Harness Kit.

Functions: Generally installed in the upper part of the engine body to measure the engine shake degree, used to adjust the ignition advance angle when the engine produces knock.

Working Principle: Detecting the working condition of the engine, whether the engine has abnormal vibration in the operation, knocking the cylinder and other abnormal phenomena, using the piezoelectric effect to convert the mechanical vibration generated during the knocking into the signal voltage. When the vibration frequency at the time of knocking coincides with the natural frequency of the piezoelectric effect sensor itself, a resonance phenomenon occurs. At this time, the sensor will output a very high knock signal voltage to the ECU, and the ECU will correct the ignition time in time to avoid knocking.
