ABSTRACT:
An ignition system for an internal combustion engine comprises a voltage boosting means which generates a high DC voltage by boosting a low DC voltage, a capacitor which charges the high DC voltage from the voltage boosting means, and ignition coil means having a secondary winding to which the high DC voltage is applied from the boosting means, wherein a high capacitive energy charged within the capacitor is supplied into one of spark plugs located within a corresponding engine cylinder in which a spark discharge has started and subsequently the output energy from the boosting means is supplied into that spark plug via the secondary winding of the ignition coil. Consequently, the ignition energy can sufficiently be supplied immediately after an ignition start to which a combustion characteristic is closely related and the complete combustion of air-fuel mixture can be achieved over the whole range of engine revolutional speed.
