Abstract
The present invention relates to a device wherein a positive voltage induced in an exciter coil at the time of a high speed rotation is sensed, a switching transistor is switched on by the terminal voltage of a time constant circuit connected in series with the exciter coil through the switching transistor and, in spite of a negative voltage then induced in the exciter coil, the discharge of a discharging capacitor connected in series with an ignition coil to the ignition coil is delayed by a thyristor for controlling the discharge in response to the above mentioned time constant characteristic to delay the ignition speed, that is, to positively prevent the over-rotation of the internal combustion engine.
