Abstract

Il est divulgué un procédé de détermination d’une dérive du débit statique de carburant d’un injecteur piézo-électrique d’un moteur thermique d’un véhicule automobile. Le procédé s’appuie sur des mesures de la pression du fluide réalisée dans la chambre d’alimentation des injecteurs pour calculer une valeur de débit statique mesuré. Cette valeur est comparée à un débit statique nominal pour déterminer l’existence éventuelle et l’amplitude de la dérive du débit statique. En outre, chaque mesure de pression est réalisée lorsque la valve de l’injecteur est fermée et l’injecteur est ouvert. De cette manière, le calcul du débit statique mesuré n’est pas influencé par des effets de variation de pression non-pertinents pour la mesure. Figure pour l’abrégé : Fig. 4
