An air inlet system for an internal combustion engine includes an inlet duct for furnishing air to the engine's cylinders, and a combination port formed within the inlet duct for inducting both recirculated exhaust gas and charge air into the engine. Mixing of the recirculated exhaust gas and the charge air is promoted by a flow director which is mounted at a downstream end of an EGR supply passage, as well as by a flow guide mounted upstream from the flow director, with the flow guide including an aerodynamic projection for causing charge air to move smoothly around the flow director and a swirl generator.
