ABSTRACT:
A catalyzer configuration, in particular for internal combustion engines, has a diffusor which widens in the direction of flow disposed upstream of a honeycomb body, a converger which narrows in the direction of flow downstream of the catalyst body, and at least one flow guiding body located within the diffusor and/or converger. In order to achieve a uniform inflow at the front side of the catalyst body without excessively throttling the exhaust gas flow, a flow guide body composed of a multiplicity of adjacent and/or imbricated channels having at least partially an increasing cross-section in the direction of flow is disposed in the diffusor. The individual channels preferably have an opening angle .alpha. that prevents burbling at the walls of the individual channels. In addition, the flow guide body can be coated with a catalytically active material, thus allowing the volume of the diffusor and/or of the converger to be used for housing catalytically active surfaces.
