Abstract
An ignition device for an internal combustion engine has a DC power source, first and second switching elements, a control signal generator for the switching elements, an ignition coil, and spark gaps. A first part of a primary coil of the ignition coil, a capacitor, the DC power source, and the first switching element form a closed circuit. A second part of the primary coil and the second switching element form another closed circuit. The signal generator generates ON signals for alternately turning on the first and second switching signals at predetermined timings based on an ignition command signal. The ignition performance of this ignition device for an internal combustion engine is improved.
