    • The invention relates to a device including a duct (4) for recirculating exhaust gases (6), connected to an intake collector duct (3) provided upstream of an intake distributor. The recirculation duct (4) extends along an axis perpendicular and radially offset relative to a central longitudinal axis of the intake collector duct (3), and comprises a tubular mixing end piece (7) provided in the intake collector duct (3) and having a cross-section that is concentric to that of the collector duct (3) in order to drive the exhaust gases along a helical trajectory so as to mix them with a first portion of the intake air flow through the mixing end piece (7), and in order to form an annular gap between an outer wall of the mixing end piece (7) and an inner wall of the collector duct (3) so that a second portion of the intake air flow through the annular gap defines a thermal barrier.

    • The recirculation device comprises, inside 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.
    • 再循环装置包括在进气管道(3)内部,其后面是歧管(6),用于引入再循环废气的装置,用于将其与引入的新鲜空气混合。该装置被设计成通过 由于与共同排气供应管道连通的双管式混合器喷嘴(10,11)形成两个相对旋转的相邻涡流(14,15),所述双管状混合器喷嘴相对于两个喷嘴相切放置并排放置。 两个涡流(14,15)自支撑到歧管(6)的出口(7)。 特别地,这种再循环装置特别地被应用于具有扁平横截面的进气管道(3)和/或具有扁平入口(5)和/或扁平通风室(8)的歧管(6),特别是 用于汽车发动机。
