Abstract

1,040,590. Ignition systems. F. L. WINTERBURN. Dec. 11, 1963 [Sept. 23, 1963], No. 48954/63. Heading FIB. [Also in Division H3] An ignition circuit for an internal-combustion engine having a coil 15, at least one spark plug to which sparking current is supplied by the coil, a battery and breaker points 14, 19 regularly opened and closed by the engine, comprises a series circuit including a capacitor C4, the primary winding of the coil and gatecontrolled switching means 1, 3, the capacitor discharging through the coil when the gate controlled switching means conducts current, the gate controlled switching means conducting current intermittently in response to sequential openings of the breaker points and a resistor in parallel with a diode connected between the gate electrode of the gate controlled switching means and the breaker points and conducting the trigger signals but preventing the triggering of the gate controlled switching means by false trigger signals created by bouncing of the breaker points following their closure. The switching means may be a silicon controlled rectifier. The trigger capacitor substantially fully discharges in the time between consecutive point openings. As shown the power supply 10 comprises a two transistor oscillator powered by the battery and rectifying means connected to the output terminal of the oscillator.
