Abstract
An ignition timing control apparatus for an internal combustion engine wherein the ignition timing of the engine is approached to the Minimum Advance for Best Torque in a partial load region of the engine, e.g. a rising supercharging region in a supercharging characteristic. When a predetermined rotating speed in the partial load region is detected by a rotating speed detector, the lagging angle of the ignition timing is provided but reduced smaller than that in the full load region where the rotating speed is above the predetermined speed. An intake pressure detector is also used for the detection of the partial load region. In response to the outputs of these detectors, a knocking signal and other signals are relatively changed in signal level so as to control the lagging angle of the ignition timing.
