A recirculation device includes an air intake duct () which is followed by a manifold (), means for introducing recycled exhaust gases, for mixing same with the fresh air let in. This device is designed to inject the exhaust gases by forming two counter-rotating adjacent vortices (), owing to a twin tubular mixer nozzle () in communication with a common exhaust gas supply duct, positioned tangentially with respect to the two nozzles, placed side by side. The two vortices () are self-sustaining to the outlets () of the manifold (). Such a recirculation device is applied, in particular, to an air intake duct () of oblong cross section and/or to a manifold () with a flattened inlet () and/or a flattened plenum (), in particular for a motor vehicle engine.
