A method of improving oxidation reactions in the exhaust gas of internal combustion engines supercharged by Pulsbeaufschlagung of catalysts

The invention relates to a method for improving oxidation reactions in the exhaust gas of internal combustion engines supercharged by Pulsbeaufschlagung of catalysts. The aim of the invention is the significant reduction of harmful exhaust gas components without high structural complexity. this is achieved by coating the catalytically active surfaces contacted by the exhaust gas in the area between the exhaust valve and the output of the exhaust gas turbine according to the invention, particularly where high turbulent flow prevails, as such. B. in the impeller of the exhaust turbine. Before being discharged from the exhaust gas turbine has a small particle size is observed, so the particles easily precipitate and can catalytically oxidize. The inventive method no additional effort is structurally necessary. Since filters omitted, no increased counter-pressure, so that the power and efficiency of the engine are not impaired is produced.
