Abstract: An exhaust gas recirculation system includes an intake manifold, an exhaust manifold, an EGR cooler, an EGR exhaust conduit and an EGR intake conduit having a diffuser. The intake manifold and the exhaust manifold are affixed to an engine head. The intake and exhaust manifolds are each in fluid communication with a plurality of combustion chambers defined by the engine head and an engine block. The EGR cooler includes a EGR cooler inlet and a EGR cooler outlet wherein the EGR exhaust conduit fluidly couples the exhaust manifold to the EGR cooler inlet. The EGR intake conduit includes a first end and a second end wherein the first end is affixed to the EGR cooler outlet and the second end is affixed to an intake passageway for the intake manifold. The diffuser includes a plurality of fins affixed to the second end and extending into the intake passageway.
