摘要： An exhaust gas aftertreatment device for a combustion engine includes an exhaust gas guide element that includes a dosage device for introducing a reduction agent into the guide element at a feed point and at least one interference element arranged upstream of the feed point, that introduces turbulences into the exhaust gas flow that is intermixed with the reduction agent. The guide element also includes a first guide portion, through which exhaust gas flows in a first flow direction, and a second guide portion, through which exhaust gas flows in a second flow direction that is opposite to the first flow direction. The first and second guide portions are fluidically connected with each other via a third guide portion, which redirects the exhaust gas from the first flow direction into the second flow direction. The feed point and the interference element are arranged in the third guide portion.

摘要： A mixing device for an exhaust system of a vehicle includes an inlet pipe, through which exhaust gas can enter a mixing chamber of the mixing device, and an outlet pipe for the exhaust gas to leave the mixing chamber. The inlet pipe and the outlet pipe form an angle. The mixing chamber includes an opening for an outlet of a dosage device, by means of which a reducing agent for exhaust gas aftertreatment is introducible into the mixing chamber. A baffle is arranged at a wall of the inlet pipe a baffle, which is induces a turbulence in the exhaust gas flow entering the mixing chamber.
