Exhaust system with mixing and/or evaporating device

摘要

A mixer/evaporator or an exhaust system (5) of an internal combustion engine (1), includes a carrier (20) surrounding, in a circumferential direction, a flat cross section of a mixing/evaporating device (12), through which exhaust gases flow and which extends at a right angle to the axial direction (17). The carrier has opposite side walls, wherein short side walls (23, 24) connect each long side walls (21, 22) to one another. Guide blades (25) project in a direction of the respective opposite long side wall, are set at an angle in relation to the axial direction and are arranged at one of the long side walls at least one axial end (26, 27). An axial end of the first long side walls is offset in the axial direction in relation to the axial end of the second long side wall on the same side of the mixing/evaporating device.

主权项

1. A device for an exhaust system of an internal combustion engine of a motor vehicle, the device comprising:
a carrier which surrounds, in a circumferential direction, a flat cross section of the device, through which cross section exhaust gases flow, the cross section extending at a right angle to an axial direction of the device, said axial direction being parallel to a direction of the exhaust gases flow, the carrier comprising: a first long side wall; a second long side wall, the first long side wall and the second long side wall being mutually opposite long side walls; a first short side wall; a second short side wall, the first short side wall and the second short side wall being mutually opposite short side walls, wherein the short side walls connect each of the long side walls to one another; and a plurality of guide blades, which project in a direction of a respective opposite long side wall and are set at an angle in relation to the axial direction, arranged at one of the long side walls at at least one axial end thereof, wherein an axial end of the first long side wall is offset in the axial direction by a distance in relation to an axial end of the second long side wall and the axial end of the second long side wall is arranged on the same side of the device in the axial direction as the axial end of the first long side wall, wherein an incoming flow-side axial end of the second long side wall is offset by the distance against the direction of flow in the axial direction in relation to an incoming flow-side axial end of the first long side wall, said one of the long side walls extending between said first short side wall and said second short side wall, each of said plurality guide blades being connected to said axial end at a position along a length of said axial end, each of said plurality guide blades being located at a spaced location from another one of said plurality of guide blades.
