Abstract

A special bearing mat (4) is used for mounting and insulating ceramic monoliths (1, 2) in a preferably oval housing (3) of an automobile exhaust system (20), especially for non-round housing cross sections. The bearing mat (4) and/or said housing is/are specially structured and/or chemically treated, especially impregnated at the points which are at risk of eroding (A) in order to increase resistance to erosion. The bearing mat (4) is adapted to suit the functioning of the exhaust system (20) during operation and is especially configured with several layers.
