ABSTRACT:
A device for catalytically converting exhaust gases in an exhaust system, especially an exhaust system of an internal combustion engine, preferably for Otto engines, includes at least two honeycomb bodies which are disposed in an outer jacket tube and through which an exhaust gas can flow in succession. The adjacent honeycomb bodies are joined to one another through the use of support elements protruding into the honeycomb bodies. The first honeycomb body is spaced apart relative to the outer jacket tube and has at least two shells joined to a jacket surface of the first honeycomb body, which are each connected to an electrical power lead. Electrically insulating joining elements each have one end joined to a shell and another end joined to the adjacent second honeycomb body. The outer jacket tube has at least one encompassing bead, which rests on a jacket tube of the second adjacent honeycomb body.
