Patent ID: 8511076

Claim:
A mixing and/or evaporating device, through which exhaust gas can flow axially, for being arranged in an exhaust gas-carrying line of an exhaust system of a motor vehicle internal combustion engine, the device comprising: an outer wall; and a plurality of blades arranged distributed in a circumferential direction, each of the blades projecting inwardly from the outer wall, wherein: each blade has a profile, at least in an area adjoining the outer wall in an axial direction of said outer wall, with a discharge edge offset in the circumferential direction in relation to a leading edge; at each of the leading edge and at the discharge edge, the profile has an angle of incidence in relation to the axial direction which is in a range of from −10° inclusive to +10° inclusive; and between the leading edge and the discharge edge, the profile has an angle of incidence in relation to the axial direction, which is greater than the angle of incidence prevailing at the leading edge and at the discharge edge.
