Abstract:
A catalytic converter assembly for an exhaust gas system of an internal combustion engine, the catalytic converter assembly comprising:a housing having a cross-section with a cross-sectional area; a catalytic converter having at most two layers formed of sheets and disposed in said housing, said catalytic converter including: at least partially curved elongated body; and at least one sheet of said sheets being a structured sheet having a structuring and a catalytically active material, said at least one structured sheet being wound on inclinedly around said at least partially curved elongated body and at least partially bears against said housing, said structuring of said at least one structured sheet in addition with one of said housing and a sheet of a layer of said at most two layers define closed passages there-between through which exhaust gases can flow and such that, as considered over said cross-section of said housing, a cross-sectional area bordered in by said closed passages constitutes at least half of a total of said cross-sectional area of said housing and defines a bordered-in cross-sectional area.
