Bypass venturi assembly and elbow with turning vane for an exhaust gas recirculation system

A bypass venturi assembly for recirculating exhaust gas in an internal combustion engine, comprising:

• a housing having an outlet, a combustion air inlet and an exhaust gas inlet;
• a center piece positioned within said housing and in communication with said combustion air inlet, said center piece defining a combustion air bypass section therein;
• a combustion air bypass valve positioned in association with said combustion air bypass section;
• an exhaust gas valve positioned in association with said exhaust gas inlet;
• and
• an elbow coupled with said outlet and defining a fluid flow path, said elbow including a vane therein positioned in association with said flow path.

A method of recirculating exhaust gas in an internal combustion engine, comprising the steps of:

• providing a housing having an outlet, a combustion air inlet and an exhaust gas inlet;
• positioning a center piece within said housing and in communication with said combustion air inlet, said center piece having a combustion air bypass section therein;
• positioning a combustion air bypass valve within said combustion air bypass section;
• positioning an exhaust gas valve in association with said exhaust gas inlet;
• coupling an elbow with said outlet, said elbow defining a fluid flow path, said elbow including a vane therein positioned in association with said flow path;
• controlling operation of each of said combustion air bypass valve and said exhaust gas valve;
• inducting exhaust gas into a flow of combustion air, dependent upon said controlling step;
• and
• splitting a flow of the exhaust gas and combustion air flowing from said outlet using said vane.
