Exhaust gas system for use with mixing device for mixing exhaust gas with reducing agent, has flow guide element of mixing device arranged on shaft, where flow guide element is moved in response to flow velocity of exhaust gas

摘要

The exhaust gas system has a flow guide element (16) of a mixing device (14) arranged on a shaft (18), where the flow guide element is moved in response to a flow velocity of an exhaust gas. Another flow guide element (22) of the mixing device is arranged on another shaft (24), where the flow guide elements occupy equal area in the flow cross-section of an exhaust line (10).
