Abstract
A current flowing in a sub-primary coil can be limited in an ignition apparatus in which a voltage, generated in a secondary coil at a timing when a current in a main primary coil is cut off, generates a secondary current, and then the sub-primary coil is energized so that a superimposition current is generated in the secondary coil and in which a sub-IC connected in series with the sub-primary coil is pulse-controlled so that a current flowing in the sub-primary coil is controlled and hence the superimposition current is controlled.
