HOUSING ARRANGED IN AN EXHAUST GAS SYSTEM FOR A COMBUSTION ENGINE

摘要

The present invention relates to a converter device intended to be arranged in an exhaust system for a combustion engine. The converter device comprises an outer casing (1), a tubular body (4) which is enclosed by said casing (1), and a passage for leading exhaust gases through the converter device. The passage comprises a first portion (17a) situated externally about the tubular body (4), a second portion (17b) situated inside the tubular body (4) and a third portion (17c) which caters for flow of exhaust gases in a radial direction between the first portion (17a) and the second portion (17b) of the passage. The third portion comprises at least one flowpath (13a, b) which provides exhaust gases with a longer flow route than a substantially rectilinear radial flow between the externally situated first portion (17a) and the internally situated second portion (17b) of the passage.
