Abstract
By means of an auxiliary voltage the semi-conductor controlled rectifier of a capacitor discharge magneto ignition system is at some limiting speed of the engine kept in its conducting condition from a time before the initiation of a charging halfwave until at least after the end of the charging halfwave. The auxiliary voltage is derived from a halfwave of polarity opposite to that which charges the ignition capacitor, and acts through a transistor to keep the SCR continuously conducting while the overspeed condition continues. The overspeed limit will be determined by the bias applied to the transistor.
