ABSTRACT:
An apparatus for the catalytic combustion of exhaust gases in an exhaust system, in particular for an exhaust system of an internal combustion engine, and preferably for Otto engines, includes first and second honeycomb bodies through which a fluid can flow in succession. At least one of the honeycomb bodies is heatable, and the honeycomb bodies each have a multiplicity of channels formed therein defining-channel walls. A plurality of support elements each have at least one end, they extending between the first honeycomb body and the second honeycomb body, they join the first and second honeycomb bodies mechanically, they protrude at least partially into the honeycomb bodies in the vicinity of the at least one end, and they are in mechanical contact with the channel walls in the vicinity of the at least one end. The support elements have a cross section and/or a shape in the vicinity of the at least one end causing the support elements thrust into selected and/or arbitrary channels to mechanically contact the channel walls in the vicinity of the at least one end.
