Abstract
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.
