The DELPHI Detonation Sensor (AS10175) is engineered to accurately detect engine knock or pinging. This critical component monitors vibrations within the engine block and signals the engine control unit (ECU) when abnormal combustion occurs. By providing this feedback, the ECU can adjust ignition timing to prevent harmful detonation, thereby protecting the engine from potential damage and ensuring optimal performance. This sensor is designed for reliable and consistent operation, contributing to fuel efficiency and a smoother driving experience.
