機関の点火時期制御装置。 The engine is equipped with a map that stores ignition timing control values according to engine operating conditions, and ignition timing control means that refers to the ignition timing control values that correspond to engine operating conditions from the map and controls ignition timing based on the map. In an ignition timing control system for an internal combustion engine, a separate map that stores ignition timing control values according to engine operating conditions for a fuel different from the standard fuel is used to measure the frequency of knocking occurrence under a predetermined engine operating condition. map switching means for switching the map referenced by the ignition timing control means to the other map under predetermined conditions; and a reference to the ignition timing control means by detecting opening of a filler lid covering a fuel inlet to the fuel tank. 1. An ignition timing control device for an internal combustion engine, comprising: clearing means for returning a map for normal fuel to a map for standard fuel.
