Abstract
An internal combustion engine ignition timing control system with knock control detects the knocking in an engine and the acceleration of the engine speed to control the ignition timing of the engine. The ignition timing of the engine is retarded in response to the detection of knocking in the engine and the amount of retard is increased as compared with the amount of retard provided under the steady-state condition when the knocking occurs during the acceleration operation of the engine and the frequency of occurrence of knocking is high.
