Title (EN) PRESSURE CONTROL IN THE COMMON RAIL SYSTEM OF A COMBUSTION ENGINE
(FR) RÉGULATION DE LA PRESSION DANS UN SYSTÈME À RAMPE COMMUNE D'UN MOTEUR À COMBUSTION
Abstract:
(EN) The apparatus according to the invention comprises a controller (7) to form a control signal, which controller is arranged to receive pressure data of the CR system (51). The apparatus also comprises a module (52) to form an internal pressure reference value based on a set pressure reference value when forming the control signal (53).
(FR) Appareil comprenant un régulateur (7) destiné à former un signal de régulation, le régulateur étant conçu pour recevoir des données de pression d'un système à rampe commune (51). L'appareil comprend également un module (52) destiné à former une valeur de référence de pression interne en fonction d'une valeur de référence de pression de consigne lors de la formation du signal de régulation (53).
