Abstract

The invention concerns a device (10) for catalytic treatment of a motor vehicle exhaust gases (G), comprising an upstream tube (12) for exhaust gas (G) intake and a downstream tube (14) for exhaust gas (G) evacuation between which is interposed a longitudinal gas (G) treating chamber comprising catalytic treatment means based on metal fibres (24) traversed by the gases (G). The invention is characterised in that the catalytic treatment means is a block (18) of metal fibres (24) impregnated with a catalytic compound arranged inside the treatment chamber (16) and comprising at least an upstream conical or tapering intake cavity (26), directly fed by the gas (G) intake tube (12) which emerges opposite the cavity (26) base and whereof the concave housing (34) forms the entry surface of the gases (G) to be treated in the fibre block.
