CATALYTIC CONVERTER TO REDUCE HYDROCARBON IN THE EXHAUST FROM A MOTOR VEHICLE

摘要

THE PRESENT INVENTION CONCERNS A CATALYTIC CONVERTER FOR VEHICLES WITH INTERNAL COMBUSTION ENGINES, ESPECIALLY FOR THE CATALYTIC CLEANSING OF EXHAUST CONTAINING LARGE PROPORTIONS OF HYDROCARBONS. IT COMPRISES A JACKET TUBE (1), IN WHICH METAL FOILS (2) AT LEAST PARTIALLY COATED WITH A CATALYTICALLY ACTIVE MATERIAL ARE ARRANGED, THE METAL FOILS BEING ARRANGED CLOSE TO THE INTERIOR SURFACE (3) OF THE JACKET TUBE (1) AND MOST OF THE CROSS SECTIONAL AREA OF THE JACKET TUBE (1) IS FREE OF METAL FOILS WITH CATALYTICALLY ACTIVE MATERIAL. THE METAL FOILS (2) CAN BE STRUCTURED, IN PARTICULAR CORRUGATED, IN AT LEAST PART OF THEIR AREA AND / OR PERFORATED (5).
