The ABAKUS 120-09-237 Detonation Sensor is a critical component for modern engine management systems. It monitors the engine for abnormal combustion events, commonly known as knocking or pinging. When the sensor detects detonation, it sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing and fuel mixture to prevent further knocking. This process is vital for protecting the engine from potential damage caused by excessive detonation, such as piston or cylinder head damage. By ensuring optimal combustion conditions, this sensor contributes to improved engine performance, fuel efficiency, and overall longevity. It is designed to meet or exceed original equipment specifications for reliable and accurate readings.
