ABSTRACT:
An alternating current of a magneto-generator (1) is rectified and is used to charge a capacitor (3), and an electric charge of the capacitor (3) is discharged into an ignition coil (9) through a thyristor (8), wherein a triggering level of the thyristor (8) is changed to be at one of two levels (V.sub.4), (V.sub.5), one of the two levels (V.sub.5) corresponding to a comparatively low engine rotational velocity which is lower than a predetermined velocity and the other level (V.sub.4) corresponding to a comparatively higher level of engine rotational velocity higher than the predetermined engine rotational velocity.
