Abstract:
A radial-mixing exhaust gas recirculation mixer is disclosed having an air supply passage having a convergent portion. An exhaust gas recirculation passage within the convergent portion includes a nozzle having a terminal end. A mixing tube is arranged downstream from the air supply passage and at least a portion of the exhaust gas recirculation passage. A mixing element is disposed in the mixing tube. In one example, a divergent portion is arranged downstream adjoining the mixing tube to increase the pressure of the mixture after the mixing tube. In one example, the exhaust gas recirculation mixer is arranged within an engine such that the air supply passage is in fluid communication with an intake manifold. The exhaust gas recirculation passage is in fluid communication with an exhaust manifold to recirculate a portion of exhaust gas to the intake manifold.
