Abstract
An ignition system for an internal combustion engine is disclosed including an ignition timing pulse generator for providing an output pulse which is a function of the angular position of the engine cylinder, and a control circuit, responsive to such output pulse, including another pulse generator comprising an astable multivibrator for turning on and off at least one switching transistor coupling a DC voltage source to the ignition transformer. The switching frequency of the transistor is determined by the control circuit to control the start, end and duration of the ignition power. The control circuit can vary, in a continuous manner, the duration of the ignition power and the switching frequency as a function of the characteristics of the internal combustion engine and its environment.
