ABSTRACT:
A first circuit is provided for producing an output which changes at a certain rate by an amount corresponding to a predetermined crank angle in the direction of retarding a spark timing each time a knocking determination signal, representing that knocking occurs, is inputted thereto with a frequency higher than a predetermined frequency and an amplitude larger than a predetermined amplitude. The output from the first circuit further changes at a smaller rate than said certain rate in the direction of advancing the spark timing in the absence of the knocking determination signal. A second circuit is provided for outputting a waveform which is reset each time a spark command signal is inputted thereto and which thereafter changes to a predetermined level at a rate depending upon the rotational speed of the engine. A third circuit is provided for comparing the outputs of the first and second circuits to output a pulse signal of a duration depending upon the level of the output of the first circuit. A fourth circuit means is provided for retarding the spark timing by an amount corresponding to the duration of the pulse signal.
