CA 2268162

A method of controlling fuel injection in an internal combustion engine including a crankshaft (58), a fuel injector (126) and a control unit (154) for outputting a signal causing a fuel injection event, with a minimum time delay between the output of the signal and initiation of the fuel injection event, the method comprising the steps of sensing the crankshaft (58) position (150), outputting the crankshaft position signal and providing an additional time delay between the output of the signal and the initiation of the fuel injection event so that the signal must be put-out at an earlier crankshaft position than would be necessary without the additional time delay, whereby changing the crankshaft speed has a greater effect upon the difference between the desired crankshaft position of the fuel injection event and the actual crankshaft position of the fuel injection event.

L'invention concerne un procédé destiné à commander l'injection de carburant dans un moteur à combustion interne, comprenant un vilebrequin (58), un injecteur (126) et un appareil de commande (154) pour émettre un signal entraînant une injection de carburant, avec un délai minimum entre l'émission du signal et le début de l'injection de carburant. Le procédé comprend les étapes suivantes: détection de la position (150) du vilebrequin (58), émission du signal de la position du vilebrequin et prévision d'un délai supplémentaire entre l'émission du signal et le début de l'injection de carburant. Ainsi, par rapport à la position du vilebrequin, le signal doit être émis plus tôt qu'il ne faudrait sans le délai supplémentaire, de sorte qu'un changement de vitesse du vilebrequin aura une incidence plus grande sur la différence entre la position voulue et la position réelle du vilebrequin au moment de l'injection de carburant.
