Honda Accord Knock Sensor

The Knock Sensor in Honda Accord automobiles is one of the vital components of the car and is responsible for the detection of an engine knock and passing the signal to the PCM where any necessary changes in the timing can be authorized. Depending on their design they may utilise piezoelectricity where the sensor translates the force vibrations into electrical signals to measure pressure bursts that define knock. Depending on the received signal the sensor can change the ignition timing in order to maximize the engine's performance and minimize the dangers of damaging the engine, when using fuel with a lower octane number. Contemporary systems are able to control the time for an individual cylinder and reach the proper boost pressure, providing maximal productivity as well as service life under various circumstances. Thus, the Honda Accord Knock Sensor technology can be a proponent and an example of development in engine management systems for better efficiency and reliability.
