【Function】: A detonation sensor is a critical component in modern engines that detects abnormal combustion. Knocking occurs when the air-fuel mixture ignites prematurely, potentially damaging the engine. When knocking is detected,the sensor sends signals to the engine control unit (ECU), which adjusts the ignition timing and fuel mixture to prevent further knocking and ensure optimal engine performance.
