Abstract

L’invention concerne un conduit d’admission (1) pour moteur Diesel à injection directe, comprenant une première extrémité (11) destinée à déboucher sur une face d’admission du moteur et une deuxième extrémité (12) destinée à déboucher dans une chambre de combustion. Selon l’invention, le conduit d’admission (1) comprend au moins trois rainures hélicoïdales (13, 14, 15, 16) espacées régulièrement entre elles sur la périphérie du conduit d’admission. Chacune des rainures hélicoïdales (13, 14, 15, 16) comprend un bord de départ (150) au niveau de la première extrémité (11) du conduit d’admission et un bord terminal (131, 141) au niveau de la deuxième extrémité (12) du conduit d’admission (1). Enfin, le bord de départ (150) et le bord terminal (131, 141) de chacune des rainures hélicoïdales (13, 14, 15, 16) sont décalés d’au moins 180° l’un par rapport à l’autre suivant l’axe principal A. Figure pour l’abrégé : figure 2The invention relates to an intake duct (1) for a direct injection diesel engine, comprising a first end (11) intended to open onto an intake face of the engine and a second end (12) intended to open into a chamber. combustion. According to the invention, the intake duct (1) comprises at least three helical grooves (13, 14, 15, 16) regularly spaced from one another on the periphery of the intake duct. Each of the helical grooves (13, 14, 15, 16) includes a starting edge (150) at the first end (11) of the intake duct and a terminal edge (131, 141) at the second end (12) of the intake duct (1). Finally, the starting edge (150) and the end edge (131, 141) of each of the helical grooves (13, 14, 15, 16) are offset by at least 180 ° with respect to each other following main axis A.
