Abstract
Disclosed herein is an ignition system for an internal combustion engine including a capacitor charged by charge power source, a thyristor for discharging the capacitor through the primary of an ignition coil and a magneto AC generator including a signal generating winding for supplying a gate signal to the thyristor. The ignition system is characterized in that rate of change of the magnetic flux interlinked with the signal generating winding has at least two successive local maximum points, so that at least two successive peaks of the same polarity appears in the voltage induced in the signal generating winding by the magnetic flux variation. The waveform of the voltage induced is utilized for ignition angle advance.
