Abstract

Système d'admission pour moteur à combustion interne comprenant un passage d'admission comportant une portion coudée située entre un filtre à air et un raccord de distribution, une pièce de raccordement pour un injecteur de carburant s'étendant de la paroi du passage d'admission située en aval de la portion coudée pour définir un passage annulaire au niveau de ladite partie coudée, et une chambre annulaire élargie formée autour dudit passage annulaire. La chambre élargie est apte à atténuer la directivité de l'air admis venant du filtre à air, à homogénéiser l'écoulement de l'air et à atténuer sa pulsation, si bien que sont améliorés le mixage du carburant de l'air et la pulvérisation du carburant, ce qui rend plus uniforme la distribution du mélange carburant-air.
