Abstract
An ignition system for a spark-ignition engine includes an ignition coil for applying a high voltage to each spark plug, a switch device connected in series with the secondary of the ignition coil for preventing in response to its conduction the supply of the high voltage to the spark plug, and a control circuit for turning on the switch device at a predetermined time after the generation of the high voltage, whereby the discharging at the spark plug is prevented under the combustion condition.
