Title (EN) ADAPTIVE CONTROL FOR A HYDRAULICALLY-ACTUATED ELECTRONICALLY-CONTROLLED FUEL INJECTION SYSTEM IN AN INTERNAL COMBUSTION ENGINE
(FR) COMMANDE ADAPTATIVE DU SYSTEME D'INJECTION DE CARBURANT A REGULATION ELECTRONIQUE ET COMMANDE HYDRAULIQUE D'UN MOTEUR A COMBUSTION INTERNE
Abstract: front page image
(EN)A method of fuel injection comprises an initial step of providing an electronically-controlled hydraulically-actuated fuel injector (14). An on-time for the fuel injector (14) that corresponds to a desired amount of fuel is determined. The fuel injector (14) is activated for that on-time. Next, the actual amount of fuel injected by the fuel injector (14) is estimated. The actual amount of fuel is compared to the desired amount of fuel. If the actual amount of fuel is substantially more than the desired amount of fuel, the on-time for a subsequent injection event is adjusted.
(FR)L'invention porte sur un procédé d'injection de fluide basé sur un injecteur (14) à régulation électronique et à commande hydraulique consistant: à déterminer la durée d'injection correspondant à la quantité de carburant désirée, à activer l'injecteur (14) pendant ladite durée, à estimer la quantité de carburant réelle injectée, à comparer la quantité désirée et la quantité réelle, et si la quantité injectée dépasse notablement la quantité désirée, à modifier la durée de l'injection suivante.
