摘要： A catalyst carrier body includes at least one housing, a honeycomb body and a passivation layer which includes a multiplicity of separate crystal agglomerations with an averaged height lying in the range of 0.3 to 1.5 μm. Various production methods are proposed which are suitable, in particular, for producing such catalyst carrier bodies. Thus, the formation of the passivation layer takes place by the blending and/or mixing of an adhesive with a passivating substance and subsequently applying the adhesive, or by roughening a region using a blast-cutting manufacturing method with corundum particles being employed as the blasting medium. A barrier is thereby provided in a very simple and cost-effective way which, for example during the formation of brazed connections, prevents the then liquid brazing material from being distributed beyond the desired tying regions as a result of capillary effects.

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 catalytic converter for vehicles with internal combustion engines which is especially suited for catalytically cleaning exhaust gas with large proportions of hydrocarbons. The converter includes a jacket tube, in which one or more metal sheets are disposed. The metal sheets are at least partially coated with a catalytically active material and they are disposed in the vicinity of an inner wall surface of the jacket tube. A predominant portion of the cross-sectional area of the jacket tube is free of metal sheets with catalytically active material. The metal sheets may be structured at least in partial regions, with corrugations and/or perforations. A catalytic converter assembly includes two converter reactors connected one after the other in the exhaust gas flow.

摘要： A catalytic converter includes a casing tube having a given internal diameter. At least two individual honeycomb bodies through which a fluid can flow in a given flow direction, are disposed in the casing tube. The honeycomb bodies are formed of structured metal layers forming flow channels. The layers are joined to the casing tube by joining techniques, such as hard brazing. The honeycomb bodies have a given theoretical strain-free diameter and have an internal layout making the honeycomb bodies elastic and permitting the honeycomb bodies to be inserted into the casing tube with an elastic compression of from 2 to 10% of the given theoretical strain-free diameter and with prestress. A method for producing a catalytic converter includes forming at least two honeycomb bodies with a given theoretical strain-free diameter from structured metal layers defining channels through which a fluid can flow in a given direction. The honeycomb bodies are subsequently successively or simultaneously inserted with prestress from at least one side into a prefabricated casing tube having a given internal diameter. The honeycomb bodies are elastically compressed by from 2 to 10% of the given theoretical strain-free diameter and/or at least partial regions of the casing tube are subsequently plastically compressed by from 2 to 10% of the given internal diameter. The layers are joined to the casing tube.

摘要： The catalytic converter configuration for exhaust systems of motor vehicles, in particular Otto engines, conducts the exhaust (at least in portions thereof) in two or more separate systems. Each system is provided with at least one catalytic converter with axial flow passages. The catalytic converters are combined into a shared monolith for the two systems which is provided with a partition at one or both of the end faces. The partition divides the cross section of the shell and it is positioned so close to the face of the honeycomb body as to be virtually seal-tight.
