ABSTRACT:
A knocking control system includes a spark timing adjusting circuit which responds to the magnitude of knocking occurring in the engine to set an amount of retardation of the timing from a reference spark timing within a predetermined range. The spark timing adjusting circuit includes a range change circuit which responds to a drive signal produced from an engine operational state determining circuit, in order to change the predetermined range.
