ABSTRACT:
The present invention relates to an electronically-controlled plasma ignition device for internal combustion engines. A device according to the invention is characterized in that it includes the same number of high-frequency electrical-current generators as the number of cylinders in the internal combustion engine, each of the high-frequency electrical-current generators being connected electrically to the primary winding of a respective electrical coil with a high transforming ratio, whose secondary winding is connected electrically to a spark plug located in the corresponding cylinder; each of these high-frequency electrical-current generators being activated transitorially, in correspondence with the combustion phase in the respective cylinder, by control means sensitive to the rotation of the drive shaft, and possibly also to the load applied, in order to generate and maintain an electronic plasma produced by a beam of high speed electrons having a high heating effect between the electrodes of the respective spark plug, during the whole period of activation. This electronic plasma optimizes combustion, increasing the overall efficiency of the engine and decreasing pollutant emissions.
