    • The present invention relates to a catalyst for an internal combustion engine, particularly of a motor vehicle, with a housing, which is assembled from at least two housing portions, telescopically inserted one into another in the throughflow direction of the housing, which is assembled from two housing portions telescopically inserted one into the other. A first monolith is mounted in a first housing portion, and a second monolith is mounted in a second housing portion. In an insertion region, an outer end section of the second housing portion and an inner end section of the first housing portion inserted into the outer end section mutually overlap. A transition zone, in which the monoliths, are spaced apart from one another in the throughflow direction, is formed within the insertion region. In this transition zone, the cross sections of the housing portions are matched to each other such that a gap is formed, passing around, closed in the circumferential direction, between the inner end section and the outer end section.
    • 本发明涉及一种用于内燃机,特别是机动车辆的催化剂,其具有壳体,该壳体由至少两个壳体部分组装而成,该壳体部分沿壳体的通过流动方向伸缩地插入另一壳体部分, 两个壳体部分可伸缩地插入另一个。 第一整体件安装在第一壳体部分中,并且第二整料件安装在第二壳体部分中。 在插入区域中,第二壳体部分的外端部分和插入外端部分的第一壳体部分的内端部分相互重叠。 在该插入区域内形成有一个过渡区,在该过渡区中,整流体在通流方向上彼此间隔开。 在该过渡区域中,壳体部分的横截面彼此匹配,使得在内端部分和外端部分之间形成在周向上通过的封闭的间隙。
