Abstract
An exhaust gas recirculation ejector system for an engine that includes an air conduit coupled to an engine providing charge air to the engine. The air conduit includes at least one bend formed therein. The at least one bend includes a port formed therein. An EGR conduit is coupled to an exhaust manifold of the engine at a first end of the EGR conduit. A second end of the EGR conduit passes through the port and extends into the air conduit at the bend defining an ejector mixing the charge air and exhaust gas before entry into the engine.

An exhaust gas recirculation ejector system for an engine comprising:
- an air conduit coupled to an engine providing charge air to the engine, the air conduit including at least one bend formed therein, the at least one bend including a port formed therein;
- an EGR conduit coupled to an exhaust manifold of the engine at a first end of the EGR conduit;
- a second end of the EGR conduit passing through the port and extending into the air conduit at the bend defining an ejector mixing the charge air and exhaust gas before entry into the engine.
An exhaust gas recirculation ejector system for an engine comprising:
- an air conduit coupled to an engine providing charge air to the engine, the air conduit including at least one bend formed therein, the at least one bend including a port formed therein;
- an EGR conduit coupled to an exhaust manifold of the engine at a first end of the EGR conduit;
- a second end of the EGR conduit passing through the port and extending into the air conduit at the bend wherein a terminal point of the second end of the EGR conduit is spaced from the inner diameter D1 in an amount of from 5 to 15 mm defining an ejector mixing the charge air and exhaust gas before entry into the engine.
An exhaust gas recirculation ejector system for an engine comprising:
- an air conduit coupled to an engine providing charge air to the engine, the air conduit including at least one bend formed therein, the at least one bend including a port formed therein;
- an EGR conduit coupled to an exhaust manifold of the engine at a first end of the EGR conduit;
- a second end of the EGR conduit passing through the port and extending into the air conduit at the bend wherein the charge air includes an outlet flow path and the second end of the EGR conduit passes through the port and includes an inlet flow path and wherein an angle A defined by an angle between the outlet flow path and the inlet flow path is from 5 to 20 degrees defining an ejector mixing the charge air and exhaust gas before entry into the engine.
