Abstract
An ignition timing control apparatus for an internal combustion engine in which the reference ignition timing of the engine is changed over or displaced according to the detected result of the occurrence of knocks owing to the kind of fuel being used for the engine. Either in the change-over determination or the displacement magnitude determination, the change-over magnitude of the reference ignition timing is initialized at a predetermined retard angle.
