Abstract
A capacitive-discharge ignition system for internal-combustion engines; the system comprises a magneto generator having a rotor provided with a plurality of magnets angularly spaced on an inner peripheral surface, in which at least two adjacent magnets have a pole of the same polarity facing a stator core having a plurality of radially extending pole members; a voltage generating winding on said pole members comprises first and second coils serially connected and wound onto adjacent pole member of the stator core to supply charging voltage to the ignition circuit and a control voltage for triggering an ignition signal generating circuit. A negative voltage is detected at each revolution of the magneto generator from an intermediate output point generator of the serially connected coils and a reference point of a voltage divider and fed through electronic control switch means to activate an electronic control switch for triggering the ignition circuit.
