Exhaust gas recirculation mixer apparatus and method

摘要

This invention relates generally fluid mixer assembly and more particularly to an exhaust gas recirculation (EGR) mixer comprising an inlet conduit, an exhaust conduit, and a shielded conduit. The shielded conduit is partially disposed in the inlet conduit and has a fluid diverting portion and fluid passing portion. The fluid diverting portion diverts intake air into a first fluid stream and a second fluid stream. Exhaust gas is passed through fluid passing portion and is mixed with the first fluid stream and second fluid stream generally at a point downstream of the shielded conduit.
