Abstract

La présente invention concerne un procédé de gestion d'un système d'injection d'un moteur (2) à combustion interne avec au moins un premier injecteur (24) et un deuxième injecteur (26, le système d'injection comportant, un capteur de pression disposé au niveau d'un rail d'injection et étant adapté pour mesurer une pression dans ledit rail d'injection, le procédé comprenant les étapes suivantes : a- mesures de la pression dans le rail durant au moins un cycle d'admission, b- calcul de la moyenne des mesures de la pression dans le rail d'injection sur le cycle d'admission dudit cylindre (12, 14), c- comparaison de la valeur moyenne des mesures de pression à une valeur de pression référence, d- modification d'au moins un paramètre de contrôle du système d'injection lorsque le résultat de la comparaison est hors d'une valeur seuil.
