Title (EN) SYSTEM AND METHOD FOR VARIATION OF THE OPENING SPEED OF A FUEL TANK VALVE
(FR) SYSTÈME ET PROCÉDÉ DE VARIATION DE LA VITESSE D'OUVERTURE D'UNE SOUPAPE DE RÉSERVOIR DE CARBURANT
Abstract:
(EN) Method for controlling the opening speed of a valve connected between a fuel tank and a filter, and configured to relieve the pressure inside the fuel tank into the filter, the method comprising the steps of: - Measuring a pressure in the fuel tank, - Measuring or inferring a fuel vapor temperature in the fuel tank, - Calculating an opening speed as a function of the pressure and the fuel vapor temperature in the fuel tank, - Opening the valve at the calculated opening speed in order to avoid corking of another valve of the fuel tank connected between the valve and the fuel tank. Assembly for putting the method into practice
(FR) La présente invention a trait à un procédé de commande de la vitesse d'ouverture d'une soupape reliée entre un réservoir de carburant et un filtre, et configurée pour relâcher la pression à l'intérieur du réservoir de carburant dans le filtre, le procédé comprenant les étapes consistant à: - Mesurer une pression dans le réservoir de carburant, - Mesurer ou déduire une température de vapeur de carburant dans le réservoir de carburant, - Calculer une vitesse d'ouverture en fonction de la pression et de la température de vapeur de carburant dans le réservoir de carburant, - Ouvrir la soupape à la vitesse d'ouverture calculée afin d'éviter le bouchage d'une autre soupape du réservoir de carburant reliée entre la soupape et le réservoir de carburant. L'invention concerne en outre un ensemble pour la mise en œuvre du procédé.
