Abstract

Arrangement for purification of hot exhaust gases from internal combustion engines and comprising a housing provided with a gas inlet (6) and a gas outlet (7) for the flow of gases through the inside of the housing, and a gas purification unit arranged in the housing between the gas inlet and the gas outlet. Between the peripheral casing wall (20) of the purification unit (16) and the wall of the housing there is a closed, gas-tight element (23) which extends peripherally round the purification unit and through the heat-insulating layer and is designed as a three-dimensional shell with an inner attachment (26) on the casing wall of the purification unit and an outer attachment (25) on the wall (8, 9) of the housing. The inner attachment is situated at a level which is nearer the outlet side of the purification unit than the level of the outer attachment. In this way the gas-tight element with its inner and outer attachments forms a gas-tight securing arrangement for the purification unit in the housing with minimal heat losses.
