ABSTRACT:
An ignition system providing variable ignition timing periods to an engine during operative mode of the system includes an angularly modulated waveform generator, an electronic control circuit electrically coupled to the generator, such control circuit being intermittently biased by the generator during the system's operation, and a power source which provides output power whose amplitude varies as a function of time, the power source being electrically connected to the control circuit. An integrator circuit may be interposed between the waveform generator and the electronic control circuit. The generator has a variable capacitor which is driven by the distributor shaft and therefore such generator provides angular modulated wave trains used to intermittently bias the control circuit. The power source is activated by the control circuit to provide non-DC output power to the ignition transformer so as to energize the igniters of the system with high energy alternating power.
