摘要 |
The invention relates to an exhaust line catalyst or muffler shell for a motor vehicle. The inventive shell comprises a tube ( 8 ) which is produced by rolling and welding a metal strip ( 12 ). At least one of the ends ( 9, 10 ) of the aforementioned tube ( 8 ) comprises a deformation produced by means of flow turning, such as to define an exhaust gas inlet ( 4 ) and/or outlet ( 5 ). The weld line ( 15 ) which closes the rolled metal strip ( 12 ) forms an angle ( 16 ) in relation to the axis ( 17 ) of the tube ( 8 ) at least in the flow turning-shaped segment(s) ( 13, 14 ) thereof. The invention also relates to a method of producing one such shell. |
