する内燃機関の点火時期制御装置。 Generates one cycle of an alternating current signal for each predetermined angular position of the crankshaft of the engine, converts the alternating current signal into a pulse signal whose rise or fall is near the zero cross point of the alternating current signal, and converts the alternating current signal into a pulse signal whose rise or fall is in the vicinity of the zero cross point of the pulse signal. Therefore, an electromagnetic pick-up type crank angle sensor configured to represent the predetermined angular position of the crankshaft is provided, and the rise or fall of the pulse signal output from the electromagnetic pick-up type crank angle sensor is used as an ignition reference signal, and the engine is operated. An ignition timing control device for an internal combustion engine configured to perform ignition control by measuring and determining ignition timing set according to a state from the ignition reference signal, comprising: an engine rotation speed detection means for detecting the rotation speed of the engine; output lag crank angle setting means for setting an output lag crank angle of the ignition reference signal by the electromagnetic pick-up type crank angle sensor in accordance with the engine rotation speed detected by the engine rotation speed detection means; and the output lag crank angle setting means. An ignition timing control device for an internal combustion engine, comprising: ignition timing correction means for correcting ignition timing based on a set output delay crank angle.
