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.

Abstract translation: 本发明涉及一种用于催化处理机动车废气（G）的装置（10），其包括用于排气（G）进气的上游管（12）和用于排气（G）进气的下游管（14） 其插入纵向气体（G）处理室，其包括基于由气体（G）穿过的金属纤维（24）的催化处理装置。 本发明的特征在于，催化处理装置是浸渍有设置在处理室（16）内部并且包括至少上游锥形或锥形进气腔（26）的催化剂的金属纤维（24）的块体（18） 由气体（G）进气管（12）直接供给，该进气管（12）出现在空腔（26）底部的相对侧，凹形壳体（34）在纤维块中形成待处理气体（G）的进入表面。
