Exhaust cleaning arrangement for an internal combustion engine of a commercial vehicle

摘要

The exhaust gas purifying catalyser modules have cylindrical casings (30). They are mounted in holes in two partitions (2,4) in the silencer, with gases flowing through the modules from a first to a second chamber. The casing of each module has narrowed ends (46). The first partition engages one of the ends, and there is a bulge (42) one quarter of the way from the other end, engaged by the other partition. A flexible bearing mat (22) inside the housing holds the catalyst body (24).
