Abstract
A mixer configuration for mixing an additive with an exhaust gas stream includes at least one overflow surface which is disposed in a mixing section of an exhaust pipe. The exhaust pipe has a cross section and a main flow direction of the exhaust gas stream. The at least one overflow surface is disposed centrally in the mixing section, is directed along the main flow direction of the exhaust gas stream and has a multiplicity of closed depressions. The mixer configuration permits an excellent mixture of the exhaust gas stream with an additive, without generating a high flow resistance in the process. A motor vehicle having a mixer configuration is also provided.
Claims11
In an exhaust pipe having a mixing section, a cross section and a main flow direction of an exhaust gas stream, a mixer configuration for mixing an additive with the exhaust gas stream, the mixer configuration comprising:
- at least one overflow surface disposed centrally in the mixing section and oriented along the main flow direction of the exhaust gas stream;
- said at least one overflow surface having a multiplicity of closed depressions formed therein.
A motor vehicle, comprising:
- an internal combustion engine;
- and
- an exhaust system connected to said internal combustion engine;
- said exhaust system including an exhaust pipe having a mixing section, a cross section, a main flow direction of an exhaust gas stream, and a mixer configuration configured to mix an additive with said exhaust gas stream;
- said mixer configuration having at least one overflow surface disposed centrally in said mixing section and oriented along said main flow direction of said exhaust gas stream;
- and
- said at least one overflow surface having a multiplicity of closed depressions formed therein.
