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 coudee pour définir un passage annulaire, et une chambre annulaire élargie formée autour dudit passage annulaire, si bien que l'air d'admission qui s'écoule à travers le passage d'admission est homogénéisé de manière à améliorer le mélange de carburant et d'air. L'injecteur de carburant est prévu dans une extrémité en saillie de la pièce de raccordement sensiblement coaxialement par rapport à la partie aval du passage, et un papillon est disposé dans le passage d'admission, en aval de l'injecteur de carburant, si bien que le carburant et l'air sont suffisamment mélangés pour homogénéiser la distribution de carburant dans un mélange carburant-air.Intake system for an internal combustion engine comprising an intake passage having an elbow portion located between an air filter and a distribution fitting, a connection piece for a fuel injector extending from the wall of the air filter passage. intake located downstream of the bent portion to define an annular passage, and an enlarged annular chamber formed around said annular passage, so that the intake air which flows through the intake passage is homogenized so as to improve the mixture of fuel and air. The fuel injector is provided in a projecting end of the connecting piece substantially coaxially with the downstream part of the passage, and a throttle is disposed in the intake passage, downstream of the fuel injector, if although the fuel and air are sufficiently mixed to homogenize the distribution of fuel in a fuel-air mixture.
