Abstract

L'invention concerne les Circuits d'injection de carburant diesel. Elle se rapporte à un circuit dans lequel du carburant à pression élevée est maintenu dans un conduit commun ayant des injecteurs qui fonctionnent à la manière de soupapes. Une commande électronique, fonctionnant d'après la charge et la vitesse du moteur, règle électroniquement le moment et la durée de l'injection de carburant. Des signaux font varier le calage en fonction d'une courbe d'avance qui dépend de la position du piston. La durée du cycle est réglée électroniquement en fonction de la position de la pédale d'accélérateur. Application aux circuits d'alimentation des moteurs diesel.
