ABSTRACT:
The present invention discloses a system which utilizes the storage action of capacitors and the characteristic of the turn-off operation due to a potential difference between the base and emitter of a transistor, and immediately after a primary short-circuit current flowing through a primary winding of an ignition coil has reached a maximum, that is, immediately after a forward induced voltage in the primary winding has reached a maximum, the primary short-circuit current is cut off in accordance with information in which the forward induced voltage in the primary winding is at its maximum to always effect the ignition operation immediately after the primary short-circuit current is at its maximum.
