Abstract
An electronic control circuit incorporated with an AC type ignition system which employs a high-frequency continuous-wave oscillator. The system includes a control winding on a transformer that has a high voltage spark signal output winding. There is a transistor in series with the control winding, to switch on and off a circuit that controls the starting and stopping of the oscillator. And, there are a pair of time delay circuits which produce delay times that are inversely proportional to the speed of an internal combustion engine that uses the ignition system. These time delay circuits may be connected so as to use only one of them. Or, they may be connected in series, so that a desired step timing change may be introduced (or not) upon demand.
