Ignition timing control device for internal combustion engines
 An ignition timing control device for an internal combustion engine, which avoids excessive knocking during sudden acceleration. There is provided means responsive to the manipulation of the engine to generate a signal. The signal thus generated is passed to actual ignition timing determining means, whereby the normal ignition timing of the engine is quickly retarded to such an extent that excessive knocking can be avoided, and the timing can be recovered immediately after the end of the retardation.
