The number of output pulses of b is counted or the engine speed is detected by the output of the engine speed detection sensor, and it is detected that the detected engine speed is equal to or higher than a predetermined speed.

The misfire circuit 24 is in the operating position "ONII" when the ignition switch 20 is stopped, and the engine speed is a predetermined speed (a predetermined idle ring speed or the like, for example, 2000 rpm). When it is detected that the engine speed has reached the engine speed, the engine is put into a misfire state. In the embodiment, the misfire circuit 24 has a misfire control thyristor 24a connected in parallel to the capacitor charging coil 13a and an engine speed detection circuit 22, and when the engine speed is equal to or higher than a predetermined speed,
An ON signal is input from the engine speed detection circuit 22 to the gate of the misfire control thyristor 24a, and
