摘要: A venturi mixing system mixes intake air with exhaust gases for exhaust gas recirculation (EGR) in an internal combustion engine. The venturi mixing system has a venturi disposed in a mixing conduit. The venturi is connected to an intake air conduit and a supply conduit. The venturi and mixing conduit form an annular cavity connected to an EGR conduit. The venturi forms a mixing chamber. One or more inset conduits connect to the venturi and extend into the mixing chamber. Each inset conduit has an end outlet and one or more side outlets. The venturi generates a lower pressure region in the intake air. The inset conduits generate a turbulence field in the lower pressure region. The inset conduits direct intake air into the turbulence field. The inset conduits direct exhaust gases through the end and side outlets into the turbulence field. The exhaust gases mix with the intake air in the turbulence field to form a combustion gas for combustion of fuel in the engine. The venturi provides the combustion gas to the supply conduit.

摘要: An apparatus includes an inlet (121) at a first end of a pipe (115), wherein a flow of fluid enters the inlet (121). A first outlet (123) is at a second end of the pipe (115). A second outlet (125) is disposed between the first end and the second end of the pipe (115). A flow deflector (201) deflects a first part of the flow out of the second outlet (125). A second part of the flow exits the first outlet (123).
