Abstract

See full text

A recirculation device includes an air intake duct (3) which is followed by a manifold (6), 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 (14, 15), owing to a twin tubular mixer nozzle (10, 11) in communication with a common exhaust gas supply duct, positioned tangentially with respect to the two nozzles, placed side by side. The two vortices (14, 15) are self-sustaining to the outlets (7) of the manifold (6). Such a recirculation device is applied, in particular, to an air intake duct (3) of oblong cross section and/or to a manifold (6) with a flattened inlet (5) and/or a flattened plenum (8), in particular for a motor vehicle engine.
