ABSTRACT:
An output signal of a vibration sensor mounted on an internal combustion engine is compared with a background noise reference signal to produce a knock signal which can accurately represent the intensity of knocking. The background noise level signal is produced by averaging a component of the vibration sensor output signal which represents the vibration of the engine other than knock-induced vibration. In order to produce a feedback signal for inhibiting the knock induced component of the sensor output signal, a first comparator compares the sensor output signal with a first reference signal having a sufficiently low level. Knock signal is produced by a second comparator which receives a second reference signal, which is proportional to the first reference signal but having sufficiently higher level, thereby enabling a precise determination of knock intensity.
