Abstract
An ignition timing control system for an automobile internal combustion engine comprises knocking detecting circuitry, ignition timing control circuitry and inhibiting circuitry. The inhibiting circuitry is operable to interrupt the supply of an output signal from the detecting circuitry to the control circuitry only when the engine, which has been operated under a particular operating condition wherein the engine speed is lower than a predetermined speed value while the actual load imposed on the engine is larger than a predetermined load value, is operated under any one of operating conditions other than such particular operating conditions.
