Abstract: Device for the catalytic cleaning of or soot removal from exhaust gases of internal combustion engines, comprising a housing that has two open end zones connected to an exhaust gas line and a flow passage for the exhaust gases between the end zones. Two flow-carrying exhaust gas treating bodies are held in housing one behind another in the direction of flow and at spaced locations from one another. A protective ring, is provided surrounding the space between the two exhaust gas treating bodies on the outside. The protective ring is held in the housing in a form-fit manner in the axial direction by a holding member surrounding it on the outside. An axial clearance is provided between the protective ring and at least of the two exhaust gas treating bodies in the installed state.

Abstract: The holding of a catalytically-active monolith in a housing in the exhaust line of a liquid fuel-operated motor is done by a holder made of a knitting wrapped about a catalyst monolith. The knitting includes a segment with an undeformed thread area, where one or more sealing strips are accommodated, so that the holding qualities are improved with good prevention of a by-passing gas flow about the monolith, and the sealing strip is protected against abrasion and destruction and is securely retained in its position.
