Mixing Device for an Exhaust System of a Vehicle

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.
