ABSTRACT:
To prevent phase-shift and pulse retardation in capacitor ignition systems, supplied with pulses from an a-c generator, the ignition capacitor is included in the armature circuit of the magneto to form, with the armature, an oscillatory circuit; the magneto supplies temporally spaced pulsed of opposite polarity, the first pulse causing oscillation of the oscillatory capacitor-armature circuit which, upon the first oscillation swing, recharges the capacitor with opposite polarity so that the next pulse derived from the magneto will add to the charge placed on the capacitor by the first oscillatory swing, thus preventing spark retardation due to phase shift upon change in engine speed.
