摘要： 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.

摘要： A catalyst carrier body includes a honeycomb body having sheet-metal layers and an axial extent. The sheet-metal layers are at least partly structured in such a way that the honeycomb body has passages through which an exhaust gas can flow. The sheet-metal layers of the honeycomb body have end regions lying radially outwardly. A tubular jacket has an edge and an axial span shorter than the axial extent of the honeycomb body. The tubular jacket is connected to the honeycomb body in at least one axial partial-region by a joining technique. A sleeve has an axial length shorter than the axial extent of the honeycomb body and is disposed on an outer region of the honeycomb body, in the vicinity of an end surface. The sleeve has an inner shell surface connected by a joining technique to the end regions of the sheet-metal layers at the end surfaces. The honeycomb body projects beyond an edge of the tubular jacket in a projecting section surrounded by the sleeve. In this way, stresses between the honeycomb body and the tubular jacket are avoided even with high thermal loads on the catalyst carrier body. A catalytic converter having the catalyst carrier body is also provided.

摘要： An exhaust gas system includes a collector for joining exhaust gas flows from two or more cylinders of a combustion engine. The collector has an outlet cross-section behind which a tubular jacket is disposed. A honeycomb body is disposed in the tubular jacket. A space through which a flow is to take place is defined between the outlet cross-section and the honeycomb body. At least one guide surface is disposed in the space for diverting at least a part of the exhaust gas flows. A method is provided for applying exhaust gas flows to a honeycomb body. The flows arrive at the honeycomb body at least partly from different directions. The exhaust gas flows are diverted by at least a first guide surface, before they impinge upon the honeycomb body, in such a way that they flow in a direction at least partly opposite to that of the exhaust gas flows, and their incidence upon the honeycomb body is thus delayed.

摘要： A honeycomb body is produced in which metal sheets are stacked and/or wound in a layered configuration. The metal sheets are suitably structured so as to form passages through which a fluid can flow. At least a part of the sheet layers initially comprises a laminate material with a layer of chromium-containing steel and a layer primarily formed of aluminum. The laminate is substantially homogenized by diffusion to a stratified sheet in a subsequent heat treatment. The honeycomb body is assembled with at least a part of the sheet layers provided a structure which increases the degree of elasticity of the honeycomb body and/or the pressure in relation to surface area of the contact locations prior to and in the heat treatment. The honeycomb body is fitted into a tubular casing with such a prestressing that in the heat treatment the contact locations between the sheet layers remain in contact.
