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