Abstract

A mixer for mixing an exhaust gas flow with a fluid injected into an exhaust gas line comprises means for generating a swirl effecting a rotating flow and means for a radial displacement in the exhaust gas flow admixed with the fluid and flowing axially through the mixer. In this respect, the swirl generation means and the radial displacement means are arranged and designed such that, viewed over the cross-section of the mixer perpendicular to the axial exhaust gas flow, at least two separate swirl regions result which are built up via tangentially acting vane-like swirl elements and at least one respective radial displacement region results which is arranged between two separate swirl regions.
