The DELPHI Detonation Sensor (AS10191) is engineered to monitor abnormal combustion events, commonly known as knocking or pinging, within your engine. By accurately detecting these vibrations, the sensor provides crucial data to the engine control unit (ECU). The ECU then adjusts ignition timing and fuel mixture in real-time to prevent engine damage and maintain optimal performance. This sensor is vital for ensuring smooth engine operation, fuel efficiency, and longevity. Manufactured by DELPHI, a trusted name in automotive components, this sensor meets stringent quality standards for reliable and consistent performance.
