ABSTRACT:
An ignition timing control apparatus for internal combustion engines is constructed to retard or advance the spark time of an engine when a knocking detector in the ignition timing control apparatus detects the occurrence or non-occurrence of knocking in the engine, respectively, and to retard the spark time by a predetermined angular value irrespective of an output signal from the knocking detector when a failure occurring in the knocking detector has been detected. Further, the ignition timing control apparatus may comprise alarm means which is actuated when a failure occurring in the knocking detector has been detected.
