Abstract:
1. A venturi mixing system for exhaust gas recirculation (EGR) in an internal combustion engine, comprising: a venturi mixing device; an intake air conduit connected to the venturi mixing device; a supply conduit connected to the venturi mixing device; at least two inset conduits connected to the venturi mixing device; an EGR conduit connected to an annular cavity of the venturi mixing device; where the venturi mixing device generates a lower pressure region in intake air from the intake air conduit; where the at least two inset conduits are in fluid communication with the annular cavity; where the at least two inset conduits generate a turbulence field in the lower pressure region; where the venturi mixing device directs exhaust gases from the EGR conduit into the turbulence field; and where the venturi mixing device provides a combustion gas to the supply conduit.
