Abstract

a. Dispositif d'injection de carburant destiné à commander la quantité injectée par la durée d'ouverture et la surface d'ouverture d'une porte placée dans le passage d'alimentation de carburant, et qui est commandée en relation avec la vitesse de rotation du moteur et la quantité d'air aspirée. b. Dispositif caractérisé en ce qu'il est prévu un dispositif d'amortissement d'un diamètre de 0,5 mm à 1,5 mm entre l'orifice de distribution de carburant d'un mécanisme de mesure et de distribution de carburant et la valve d'injection d'un injecteur de carburant à valve automatique.
