Knock Sensor

Knock Sensor is installed on the cylinder wall of the engine, which is adapted to detect whether a knock occurs in the engine, so that the spark advance angle can be adjusted correspondingly. A vibrating plate is arranged inside the sensor. When a knock occurs in the engine, resonation appears on the vibrating plate, and this vibration acts on a piezoelectric element, the piezoelectric element generates a voltage. When the engine is in a working state of acceleration or high load and a slight knock occurs, the sensor inputs a knock signal to an ECU. When the ECU receives the knock signal from the Knock Sensor, it gives instructions to reduce the spark advance angle, until the knock ceases.
