  • Knocking detector
    Patent number: 4423621
    Abstract: A rectifier rectifies the output of a sensor which senses vibrations of an engine. The output from the rectifier is supplied through a smoothing circuit to a comparator where the smoothed rectified output from the smoothing circuit and the output of the sensor are compared to obtain a signal representing knocking when the knocking occurs. This signal is used to cut off supply of the rectified signal from the rectifier to the smoothing circuit during knocking.
