Abstract

Dans un moteur à combustion interne multicylindre dont les cylindres (1, 2) sont disposés en deux rangées, les cylindres (1) d'une des rangées étant disposés en quinconce par rapport aux cylindres (2) de l'autre rangée et les axes médians longitudinaux des cylindres d'une des rangées formant un angle avec les axes médians longitudinaux des cylindres de l'autre rangée, les soupapes d'échappement (11, 11') sont disposées près du plan de symétrie (S) s'étendant entre les rangées de cylindres, tandis que les soupapes d'admission (7, 7') sont disposées à l'extérieur, un arbre à cames d'échappement commun (14) situé à l'intérieur étant prévu pour toutes les soupapes d'échappement des deux rangées de cylindre, et un arbre à cames d'admission spécifique (15, 15') étant prévu pour les soupapes d'admission de chaque rangée de cylindres.
