ABSTRACT:
An engine ignition system includes a throttle sensor for detecting the position of a throttle valve. A control circuit is responsive to the detected throttle signal as well as the signals from other negative pressure and engine rpm sensors to generate a spark plug discharge start signal and a discharge stop signal. A high voltage generator supplies a high voltage to the respective spark plugs during the time interval between the time that the discharge start signal is generated and the time that the discharge stop signal is generated.
