The FEBI BILSTEIN 106965 Detonation Sensor is a critical component for modern engine management systems. It is designed to accurately detect abnormal combustion events, commonly known as engine knock or detonation. When detonation occurs, the sensor sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing to retard the spark, thereby preventing potential engine damage caused by the uncontrolled combustion. This process is vital for maintaining engine health and performance under various load conditions. Crafted with high-quality materials, this sensor ensures reliable and precise readings. Its robust construction is built to withstand the harsh operating environment within the engine bay, guaranteeing longevity and consistent performance. Proper functioning of the detonation sensor contributes to optimal fuel efficiency and reduced emissions.
