Exhaust gas treating device for an internal combustion engine

摘要

The device (1) has a housing (2) in which an exhaust gas pipe (4) flowing into a cup shaped mixing chamber (3) is provided. A flow device (6) of exhaust gas returns radially outside of the exhaust gas pipe. An open end (7) of the cup-shaped mixing chamber flows into a collecting area (8), which is formed such that it supplies the exhaust gas to a subsequent selective catalytic reduction (SCR) catalyst (9). The exhaust gas pipe is formed as a venturi nozzle, or has an insert that is designed as venturi nozzle.
