    摘要: The present invention provides a device and a method for supplying a fuel or a reducing agent, where a fuel or reducing agent supplied by injection can be vaporized and/or a fuel or reducing agent having high reactivity can be provided, and provides a plasma torch (30) usable therefor. The device for supplying a fuel or a reducing agent comprises a plasma torch (30) for converting a gas (23, 33) into a plasma and blowing out the plasma, and an injector (18) for injecting a fuel or a reducing agent to a region (20) where the plasma is supplied. The method comprises converting a gas (23, 33) into a plasma, blowing out the plasma, and injecting a fuel or a reducing agent to the plasma region (20).

    摘要: The present invention provides an exhaust gas purifying apparatus 10 which can effectively purify an exhaust gas with the use of a plasma. The present exhaust gas purifying apparatus 10 comprises a NOx purifying catalyst 1 disposed in an exhaust gas pipe 11 for an internal combustion engine (ENG); a plasma generator 2 for converting a gas into a plasma and supplying the plasma to the exhaust pipe at the upstream of the NOx purifying catalyst; a switching device 3 for selectively supplying one of a recirculated exhaust gas 13 and air 12 as a gas to be converted into a plasma to the plasma generator 2; and an injector 4 for adding a reducing agent to the gas 14 to be converted into a plasma or a plasma 15 converted from the gas by the plasma generator. The present invention further provides a method for controlling the exhaust gas purifying apparatus.
