<p>A train of sparks is maintained over one or more prolonged periods of the engine cycle. The sparks are produced by a high frequency voltage, the application and the cut-off of which are controlled by a detector 4 which provides a signal representing the position of the cylinder in the engine. The high voltage is produced by a circuit 3 for cutting off a continuous current, which is controlled by a continuously-running low-power oscillator 1 via a switch 2 controlled by the detector 4. The device makes it possible to achieve total combustion of the mixture, and the sparks can be maintained possibly up to the end of the exhaust phase. <IMAGE></p> |
