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.
