<p>IGNITION SYSTEM EMPLOYING CONTROLLEDDURATION CONTINUOUS-WAVE HIGH-FREQUENCY SPARK ENERGY (D#73,508-F) An ignition system for internal combustion engines. It generates a controlled-duration continuous-wave high-frequency spark, and employs an output transformer in an oscillator which includes a control winding for starting and stopping the oscillator. There is an electronic switch in series with the control winding; and the spark intervals, including duration thereof, are determined by photoelectric engine-timed means that employ a phototransistor. There is a control circuit for the electronic switch, which circuit includes means for minimizing the response time of the phototransistor. -I-</p> |
