Abstract

L’invention concerne un procédé de commande d’un injecteur dans un système à rail commun comprenant les étapes suivantes : détection (E2) d’une augmentation entre un débit statique observé et un débit statique de référence et détermination (E3) d’une consigne de pression rail corrigée (Pcor) garantissant une même quantité de fluide injecté avec le débit statique observé que celle injectée avec une pression de référence (Pref) et le débit statique de référence. L’invention permet ainsi avantageusement de conserver une même durée d’injection. Figure 2
