摘要

The device has an injector type introducing unit comprising an opening (41) and introducing a reducer or precursor of the reducer for a selective catalytic reduction of nitrogen oxides. A mixer (5) mixes the exhaust gas and the reducer or conversion of the precursor into the reducer. A selective catalytic reduction catalyst (6) is used for selective catalytic reduction of nitrogen oxides. An oxidation catalyst, the introducing unit, the mixer and the selective catalytic reduction catalyst are assembled in a cylindrical shaped single envelope (2). An independent claim is also included for a vehicle comprising an assembly.
