Patent attributes
An exhaust system mixer (12) mixes a reactant with an exhaust gas flow (3) and includes a pipe section (13), which borders a flow cross section (16), through which the exhaust gas flows (3), in the circumferential direction (17), and which extends in an axial direction (18) from a first axial side (19) to a second axial side (20), and a plurality of guide blades (14, 15), which project from the pipe section (13) at least on one of the axial sides (19, 20), so as to protrude into the flow cross section (16). Guide blades (14, 15) on an axial side, which follow each other in the circumferential direction (17), include a first guide blade group (21), arranged on the respective axial side (19, 20), axially offset in relation to the guide blades (15) of the second guide blade group (22), to reduce a pressure drop.
