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.
