Title (EN) INTERNAL COMBUSTION ENGINE FUEL INJECTION SYSTEM
(FR) SYSTEME D'INJECTION DE CARBURANT DANS UN MOTEUR A COMBUSTION INTERNE
Abstract:
(EN) A system comprising a fuel tank (20), pressurised fuel accumulation means (21), means (26) for connecting the accumulation means to means (27) for injecting fuel into the engine, and a control valve (29) positioned between the connecting means (26) and the tank (20) and connected to control means (30) for opening and closing the valve to generate a fuel pressure wave by means of a surge effect in the connecting means up to the injection means, and thereby inject fuel into the engine. Said system further comprises means (30) for controlling the fuel pressure in the accumulation means (21) to enable adjustment of the fuel pressure wave amplitude in the injection means (27) and thus also of the amount of fuel injected into the engine, in accordance with the operating conditions thereof.
(FR) Ce système, comportant un réservoir de carburant (20), des moyens (21) d'accumulation sous pression de carburant, des moyens (26) de raccordement des moyens d'accumulation à des moyens (27) d'injection de carburant dans le moteur, et une vanne (29) de commande implantée entre les moyens de raccordement (26) et le réservoir (20) et reliée à des moyens de commande (30) de celle-ci à l'ouverture et à la fermeture pour engendrer par effet de coup de bélier, une onde de pression de carburant dans les moyens de raccordement jusqu'aux moyens d'injection, permettant d'injecter du carburant dans le moteur, est caractérisé en ce qu'il comporte en outre des moyens (30) de commande de la pression de carburant dans les moyens d'accumulation (21) pour permettre un réglage de l'amplitude de l'onde de pression de carburant dans les moyens d'injection (27) et donc de la quantité de carburant injectée dans le moteur, en fonction des conditions de fonctionnement de celui-ci.
