Abstract
An ignition timing control method and apparatus for an internal combustion engine mounted on a motor vehicle can prevent the occurrence of the knocking in the internal combustion engine. When the engine is running within a specific speed range and the transmission gear ratio is high, the control device determines that the engine is running under a condition where knocking is likely to occur. Accordingly retarding of the ignition timing in the internal combustion engine is accomplished in order to prevent knocking.
