Abstract
An internal combustion engine according to the present invention has an ignition control device. When a rotational speed of the internal combustion engine increases beyond a predetermined rotational over speed, the ignition control device advances an ignition timing of the ignition plug to a first BTDC angle where proper combustion is performed. Further, the ignition control device performs a misfire stroke or strokes of the ignition plug in one rotation or rotations of the crankshaft after the proper combustion is performed by activating the ignition plug at the first BTDC angle.
