The DELPHI Detonation Sensor (AS10258) is engineered to accurately detect engine knock or detonation. This critical component monitors vibrations within the engine block, signaling the engine control unit (ECU) when abnormal combustion occurs. By providing timely feedback, the ECU can adjust ignition timing to prevent engine damage and maintain optimal performance. This sensor is designed for reliable operation and durability, ensuring consistent detection across various driving conditions. Proper functioning of the detonation sensor is vital for fuel efficiency, engine longevity, and overall vehicle health.
