Chevrolet S10 uses Knock Sensor as a significant part of the vehicle to determine the presence of knock in the engine and sends the signal to PCM in order to control ignition timing. Usually piezoelectric, the sensor works by changing the variation in vibration to electrical signals that are constantly analyzed for pressure surges associated with knock. This enables the timing of the ignition to be altered infinitesimally thus maximizing the efficiency and reducing the chances of engine knock. Some advanced systems can even set the duration for the firing of each cylinder and control boost pressure, making sure that the engine will perform optimally and will last long despite the conditions. The Knock Sensor in Chevrolet S10s helps in the efficient running of the engine and is crucial when it comes to issues touching on detonation.
