Abstract: An exhaust gas recirculation system for an engine includes a conduit, and a mixer. The conduit is configured to direct to direct exhaust gas away from an exhaust manifold. The mixer is configured to direct exhaust gas from the conduit, into an engine air intake system. The mixer is arranged with an exhaust gas mixing volute chamber having a plurality of mixing vanes configured to direct the exhaust gas into a central intake airflow upstream of an intake manifold.

Abstract: An exhaust gas recirculation system for an engine includes a conduit, and a U-shaped exhaust gas mixer. The conduit is configured to direct an exhaust gas away from an exhaust manifold. The U-shaped exhaust gas mixer is configured to direct exhaust gas from the conduit and into an engine air intake system. The U-shaped exhaust gas mixer is arranged with a pre-mixing cavity configured to disperse the exhaust gas and entraining the exhaust gas into an intake air flow prior to distribution into an intake manifold of an engine.

Abstract: An engine system includes an engine having an intake manifold, a turbocharger having a compressor, and an exhaust gas recovery (EGR) mixer coupled between the compressor and the intake manifold. The EGR mixer includes a central air duct having a central axis, an annular ring circumscribing the central duct and having an inlet connectable to an EGR system and an outlet in fluid communication with the central air duct, and a vane assembly disposed in the central air duct upstream of the annular ring and having a plurality of vanes configured to swirl air passing therethrough.

Abstract: An exhaust gas recirculation system for an engine includes a first conduit, a second conduit, and a mixer. The first conduit is configured to direct a first portion of exhaust gas away from a first exhaust manifold. The second conduit is configured to direct a second portion of exhaust gas away from a second exhaust manifold. The mixer is configured to direct the first and second portions of the exhaust gas from the first and second conduits, respectively, into an engine air intake system. The mixer is arranged to segregate the first and second portions of the exhaust gas while the first and second portions of the exhaust gas are within the mixer. The mixer forms a ring about a perforated tube. The mixer is configured to direct the first and second portions of the exhaust gas into the air intake system via the perforated tube.
