Title (EN) METHOD FOR CONTROLLING A CAPACITIVE ACTUATOR OF A FUEL INJECTION VALVE OF AN INTERNAL COMBUSTION ENGINE
(FR) PROCEDE PERMETTANT DE COMMANDER UN ACTIONNEUR CAPACITIF D'UNE SOUPAPE D'ADMISSION DE CARBURANT D'UN MOTEUR A COMBUSTION INTERNE
(DE) VERFAHREN ZUM ANSTEUERN EINES KAPAZITIVEN STELLGLIEDES EINES KRAFTSTOFFEINSPRITZVENTILS EINER BRENNKRAFTMASCHINE
Abstract:
(EN) The invention relates to a method for controlling a capacitive actuator of a fuel injection valve of an internal combustion engine. A capacitive actuator of a fuel injection valve of an internal combustion engine is charged with different charging times or charging quantities for the pre-injection and the main injection. Either the charging times are constant throughout the load or speed range of the internal combustion engine or the charging times or charging quantities are dependent on the load or speed of said internal combustion engine.
(FR) L'invention concerne un actionneur capacitif d'une soupape d'admission de carburant d'un moteur à combustion interne. Cet actionneur est chargé avec différents temps ou volumes de charge pour la pré-injection et l'injection principale. Dans toute la plage de charge ou de régime du moteur à combustion interne, les temps de charge sont constants ou bien les temps ou volumes de charge sont fonction de la charge ou du régime du moteur à combustion interne.
(DE) Ein kapazitives Stellglied eines Kraftstoffeinspritzventils einer Brennkraftmaschine wird mit unterschiedlichen Ladezeiten oder Ladungsmengen für Vor- und Haupteinspritzung geladen; wobei im gesamten Last- oder Drehzahlbereich der Brennkraftmaschine entweder die Ladezeiten konstant sind, oder die Ladezeiten oder Ladungsmengen von Last oder Drehzahl der Brennkraftmaschine abhängig sind.
