    • 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.
    • 本发明提出了一种用于机动车辆发动机的废气(G)的催化处理的装置(10),该装置包括用于废气(G)到达的上游管(12)和 在其之间插入纵向气体处理外壳(16)(G)的下游废气排出管(14),所述纵向气体处理外壳(16)包括穿过其中的金属纤维基催化处理装置(24) 其特征在于,所述催化处理装置是浸渍有布置在所述处理室(16)内的催化剂化合物的金属纤维(24)的块(18) 并且其包括至少一个具有圆锥形或截头圆锥形形状的入口空腔(26),所述入口空腔由管(14)直接供应用于气体(G)的到达,所述气体朝向空腔(26)的底部敞开, 并且其凹形外壳(34)构成纤维块中待处理的气体(G)的入口表面。

    • A muffler with catalytic converter (1) in which at least one catalytic converter element (2) is located in the muffler so that an essential part of all exhaust gases (3) from the engine are forced to pass through the element (2) and be converted there into cleaned exhaust gases (4). The element is designed as an essentially self-supporting body of catalytic material, which is hollow or partly concave and has inner and outer surfaces (6, 7), e.g. the body is shaped as a circular or non-circular sleeve, or possibly even as a narrowing sleeve (8), a dome-shaped or angular bowl-shaped body (5), and the element is, either directly or via intermediary elements, mounted to a dividing part inside the muffler, such as a partition wall (10), an outlet duct (11) or an inlet duct (12), and the mounting is so arranged that at least one end surface (13, 14) is kept fixed at the same time as the element is supported at the outer surface (7) by at least one part (10, 18, 23, 24), while the inner surface is essentially free.
    • 一种具有催化转化器(1)的消音器,其中至少一个催化转化器元件(2)位于消声器中,使得来自发动机的所有废气(3)的主要部分被迫通过元件(2)和 被转换成清洁的废气(4)。 该元件被设计为基本上自支撑的催化材料体,其是中空的或部分凹的,并且具有内表面和外表面(6,7)。 该主体成形为圆形或非圆形套筒,或​​者甚至可以作为缩小套筒(8),圆顶形或角形的碗状主体(5)形成,并且该元件直接地或经由中间元件, 安装在消音器内部的分隔部分,例如分隔壁(10),出口管道(11)或入口管道(12),并且安装件被布置成使得至少一个端面(13,14)是 在元件被支撑在外表面(7)处至少一个部分(10,18,23,24)的同时保持固定,而内表面基本上是空闲的。
