ABSTRACT:
A plasma injector for an internal combustion engine, in one embodiment, includes two spaced apart and parallel donut shaped disk electrodes, between which a horizontally outward moving plasma is formed via a high voltage applied across the electrodes. The present invention is characterized by its efficient use of input electrical energy via electronic circuitry for driving the plasma injector. An ignition source provides an ignition plasma kernel which is several orders of magnitude larger than that produced by conventional spark plugs.
Use of very lean combustible mixtures, in which the dilution of the mixture is achieved by use of exhaust gas recirculation, is made possible by the present ignition system. Considerable improvement in engine efficiency, and a major reduction in NO.sub.x exhaust gas pollutants are obtained via the present ignition.
