  • Patent number: 6908596
    Abstract: Without of affect of sulfur in fuel, NOx in exhaust gas is decomposed completely using discharge and low temperature of 300 C. degree, to establish technique for generating NO2 for necessary to oxidize a particle substance in a real time. The generated NO2 and ozone and active oxygen generated in oxygen atmosphere are used an oxidation agent the particle substance is decomposed completely using discharge and low temperature of 300 C. degree. As to NOx in exhaust gas, No is decomposed completely using a thin and narrow wire shape bear wire and NO2 for necessary to the particle substance is generated and is processed in response to operation condition of the engine in low temperature of 300 C. degree.
