ABSTRACT:
An ignition system for an internal combustion engine includes an ignition coil system for applying a secondary generated voltage of an ignition coil and a DC high voltage to each of spark plugs and an ignition control circuit for controlling the ignition coil system. The ignition control circuit includes an ignition coil control circuit for energizing and deenergizing the ignition coil and a DC high voltage generating circuit for generating a DC high voltage. The DC high voltage generating circuit generates the DC high voltage from before the secondary generated voltage of the ignition coil causing capacitive discharge at a spark plug to a predetermined time or crank angle after the start of the discharge.
