Abstract

The invention relates to a device for purifying the exhaust gases of internal combustion engines, comprising a catalytic converter with a metal matrix fixed by welding into a casing. There is provided, considering the direction of flow of the exhaust gases, at 2 to 10 mm before the catalytic converter 1, on the inner wall of the casing 2, 3, 4, a collar 5 directed radially towards the inside and whose height lies between 3 and 15% of the diameter of the catalytic converter 1, whilst, however, being at least 1 mm. Application to the automotive industry. <IMAGE>
