Abstract
Procédé de diagnostic d’un système d’injection comportant :- une rampe d’injection munie d’un capteur de pression, et- une pompe haute pressionledit procédé comportant les trois étapes suivantes après détection d’un défaut de fonctionnement du système d’injection : - a) isolation de la rampe d’injection et détermination d’une éventuelle variation de pression dans la rampe d’injection, - b) sortie de carburant de la rampe d’injection mais sans alimenter la rampe d’injection en carburant et détermination d’une éventuelle variation de pression dans la rampe d’injection, - c) entrée de carburant dans la rampe d’injection mais sans laisser sortir du carburant de la rampe d’injection et détermination d’une éventuelle variation de pression dans la rampe d’injection, et - d) une quatrième étape de détermination d’un diagnostic en fonction des variations de pression constatées lors des trois étapes précédentes selon des schémas prédéterminés. Figure de l’abrégé : Figure 2Method for diagnosing an injection system comprising:- an injection rail fitted with a pressure sensor, and- a high-pressure pump, said method comprising the following three steps after detection of an operating fault in the injection: - a) isolation of the injection rail and determination of any pressure variation in the injection rail, - b) fuel exit from the injection rail but without supplying the injection rail with fuel and determination of any pressure variation in the injection rail, - c) fuel entering the injection rail but without allowing fuel to leave the injection rail and determining any pressure variation in the injection rail, and - d) a fourth step of determining a diagnosis according to the pressure variations observed during the three preceding steps according to predetermined diagrams.
