1；Knock detection: The knock sensor is a key component in the engine management system (EMS), used to detect whether knocking occurs during engine operation. 2；Magnetostrictive type: When the body vibrates, the magnetic core is displaced, changing the magnetic flux inside the induction coil and generating induced electromotive force. 3；Adjust ignition timing: When the engine knocks, the knock sensor provides a knock signal to the computer (some through the control module PCM), and the computer readjusts the ignition timing based on the signal to prevent further knocking 4；Protecting the engine: Timely adjustment of ignition timing can effectively protect the engine and avoid excessive impact on mechanical components such as pistons, connecting rods, and crankshafts caused by detonation, 5；Durability: Knock sensors are usually very durable and will only be damaged due to their own failure. They can withstand various vibrations and harsh environments during engine operation.
