Abstract
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.
