Abstract

The ignition system of an internal combustion engine having a crankshaft includes a charging generator having a mechanical input coupled to the engine crankshaft and having an electrical output winding, the charging generator being operative for generating an A.C. output voltage. The system furthermore includes an ignition capacitor. A rectifying stage connects the output winding of the charging generator to the ignition capacitor, and is operative for applying across the ignition capacitor voltage half-cycles of only one predetermined polarity. An ignition transformer has a primary winding and a secondary winding. A fuel igniting unit is connected across the secondary winding of the ignition transformer. A discharge circuit connects the ignition capacitor to the primary winding of the ignition transformer and includes an electronic discharge switch having a control input. The discharge circuit is operative when the electronic discharge switch is conductive for discharging the ignition capacitor through the electronic discharge switch and through the primary winding of the ignition transformer. A triggering signal generator has a mechanical input coupled to the engine crankshaft and has an electrical output connected to the control input of the electronic discharge switch for controlling the conductivity of the latter, and is operative for producing triggering signals synchronized with voltage half-cycles produced by said charging generator. A control circuit is connected to the triggering signal generator and is connected to the charging generator and is operative for preventing the triggering signal generator from rendering the discharge switch conductive when the voltage half-cycle being generated by the charging generator is of a predetermined first polarity and is operative for permitting the triggering signal generator to render the discharge switch conductive when the voltage half-cycle being generated by the charging generator is of opposite second polarity.
