Abstract

Le système d'alimentation en carburant pour moteur à combustion interne comprend un ensemble de pompage (5 a, 5b) disposé entre une rampe d' injection de carburant (4) munie d'un capteur de pression (22), et un réservoir de carburant (6), une première vanne commandée (9) de régulation du débit de carburant alimentant une pompe haute pression (5b) de l' ensemble de pompage, une deuxième vanne commandée ( 1 1 ) de régulation de la pression du carburant accumulé dans la rampe d' injection (4), et des moyens de détermination (30) d'une pression de consigne dans la rampe d' injection (4), en fonction de paramètres de fonctionnement du moteur ( 1 ). Le système comprend deux boucles fermées de régulation desdites première (9) et deuxième (1 1 ) vannes commandées, les deux boucles fermées de régulation utilisant la pression mesurée dans la rampe d' injection (4), étant connectées en cascade, et étant actives simultanément.
