Abstract
An ignition timing control apparatus for an internal combustion engine having a supercharger in which a feedback control of decreasing the supercharged pressure is done in order to obviate knocking, wherein when a detection is made of a knocking with a detection of decrease in the controlled supercharged pressure under the condition of a constant throttle opening-degree, the ignition timing just at the detection of knocking is held for the control of ignition timing.
