Abstract

The container arrangement is for incorporation in the exhaust gas system of an internal combustion engine and comprises an outer casing (1) enclosed by a tubular body (4) and a passage for conducting exhaust gases through the container. The passage has a first part extent (17a) located externally around the tubular body, a second part extent (17b) located inside the tubular body and a third part extent (17c) which handles the flow of exhaust gases between the first and second part extents. The third part extent incorporates at least one flow path, which constitutes an extended flow extent for exhaust gases in relation to a straight-line radial flow between the first and second part extents.
