Lincoln MKX cars employ the Knock Sensor for it measures engine knock, an occurrence caused by wrong ignition timing. This unit signals the PCM to be able to alter the ignition timing in order to reduce on the occurrence of detonation. In most of the Lincoln MKX models, the knock control strategy uses piezoelectric knock sensors whereby pressure peak signals related to knocking are continuously monitored from the sensed vibrations. When knock is sensed the PCM reduces the ignition timing gradually until normal combustion is regained; gradual advancement of timing is then made. It assists to preserve engine efficiency when burning standard unleaded and, on the same note, decrease the probability of harm, even if low-octane fuels are used. Higher systems can also change the spark for every cylinder and modify the boost pressure for better operation form one form or the other of the car's usage.
