Abstract

The controlled-duration continuous-wave HF ignition system for IC engines has an output transformer with a control winding. The system has an oscillator with the output transformer included inside. The oscillator generates spark energy, and an engine-timed unit controls an electronic switch that starts and stops the oscillators by breaking and making a loading circuit for the control winding. The arrangement is such that the engine-timed unit controls the beginning of all spark intervals, and the end of each spark interval at less than a predetermined speed of the engine. But only time constant element controls the end of each spark interval at more than the predetermined speed of the engine.
