摘要
A catalytic converter for vehicles with internal combustion engines which is especially suited for catalytically cleaning exhaust gas with large proportions of hydrocarbons. The converter includes a jacket tube, in which one or more metal sheets are disposed. The metal sheets are at least partially coated with a catalytically active material and they are disposed in the vicinity of an inner wall surface of the jacket tube. A predominant portion of the cross-sectional area of the jacket tube is free of metal sheets with catalytically active material. The metal sheets may be structured at least in partial regions, with corrugations and/or perforations. A catalytic converter assembly includes two converter reactors connected one after the other in the exhaust gas flow.
