Abstract (en)
Production involves introducing an exhaust gas treatment element (3) axially into a cylindrical housing jacket (2), open on at least one side. The housing jacket inner side has an outlet cross section (7), which is greater than the outer cross section (10) of the exhaust gas treatment element. A funnel (4) is introduced axially into the axial end area (8) of the housing jacket whereby the outer cross section (11) of the funnel is smaller than the inner outlet cross section of the housing jacket. The housing jacket undergoes cross section reduction in such a manner that the housing jacket within the area, within which exhaust gas treatment element is arranged, has a first end cross section (13) inside, which is equally large as the outer cross section of the exhaust gas treatment element and within the respective final area, within which the respective funnel is arranged, has a second end cross section (14) inside, which is just as large as the outer cross section of the funnel. An independent claim is also included for the exhaust gas treatment device.
