A method and apparatus for controlling knocking in an internal combustion engine comprises the steps of detecting the knocking which occcurs in the internal combustion engine having a plurality of cylinders, correcting the ignition timing of a cylinder in which the knocking occurred, by a predetermined value based on the intensity of the knocking, and also correcting the ignition timing of the other cylinders by the predetermined value multiplied by certain coefficients.

A method of controlling ignition timing of an internal combustion engine having a plurality of cylinders in which ignition occus sequentially in a predetermined order, comprising the steps of: (a) detecting the occurrence of a knocking condition in any one of said cylinders; (b) determining in which one of said cylinders said knocking condition has occurred; (c) producing a signal representative of the intensity of the detected knocking condition; (d) correcting the ignition timing of said any one cylinder based upon said knocking condition intensity representative signal; and (e) correcting the timings of ignition of those of said cylinders other than said any one cylinder by respective timing values dependent upon the intensity of said knocking condition representative signal adjusted by respective prescribed coefficients for said other cylinders. An apparatus for controlling the ignition timing of an internal combustion engine having a plurality of cylinders on the basis of knocking which occurs in the engine, comprising: a knock sensor mounted to the engine for detecting the occurrence of a knocking condition in the engine and producing a first signal representation thereof; means for producing a second signal in response to said first signal and representative of the intensity of the knocking condition represented by said first signal; means for determining in which one of said cylinders said knocking condition, as represented by said first signal, has occurred; means for correcting the ignition timing of said one cylinder based on said second signal; and means for correcting the timing of ignition of those of said cylinders other than said one cylinder by respective timing values dependent upon said second signal adjusted by respective prescribed coefficients for the other cylinders.
