Abstract: A catalyst carrier configuration includes a housing and at least one catalyst carrier body disposed in the housing. The catalyst carrier body has partition walls defining a plurality of passages for an exhaust gas. A flange surrounds the catalyst carrier body and extends radially outwards from the catalyst carrier body. The flange has a section that extends at least partially into an outer wall of the housing and can be disposed between a cylinder head and a manifold of an internal combustion engine. The catalyst carrier configuration can be mounted close an internal combustion engine. A structural unit having at least two catalyst carrier configurations and an exhaust system are also provided.

Abstract: A honeycomb body configuration includes a honeycomb body with a fluid inlet side and a fluid outlet side. The honeycomb body is formed of at least partially structured sheet metal layers which form channels through which a fluid can flow. The honeycomb body is surrounded by an inner tubular jacket and an outer tubular jacket provided concentrically in relation thereto. The inner tubular jacket is configured as a corrugated hose in at least one axial subregion thereof. The inner tubular jacket has at least one further axial subregion which lies smoothly against the honeycomb body. The corrugated subregion and the outer tubular jacket are connected at least in a longitudinal partial region of the corrugated subregion.
