ABSTRACT:
In a contactless capacitor discharge type ignition system for an internal combustion engine in which a timing signal coil is connected to a control gate of a switching thyristor for discharging a stored charge on a capacitor, a series circuit is connected across the timing signal coil in order to pass a controlled current in one direction. By the shortcircuit of current flowing through the coil, the output of the timing signal coil of the opposite direction is so influenced as to retard the spark timing, whereby the spark retard can be carried at a relatively high speed operation of an engine.
