Abstract

L'invention concerne un procédé de fonctionnement d'un système de commande d'émissions par évaporation destiné à être utilisé avec un réservoir de carburant qui stocke et distribue du carburant à un moteur à combustion interne et qui consiste à utiliser un ensemble d'arrêt de mise à l'air libre. L'ensemble ouvre et ferme sélectivement au moins une soupape pour fournir une surpression et une mise sous vide au réservoir de carburant. L'ensemble d'arrêt de mise à l'air libre réalise une mise à l'air libre sélective vers une cartouche de purge. La au moins une soupape est fermée, de sorte que de la vapeur est empêchée de passer du réservoir de carburant à la cartouche de purge. Un événement de purge est réalisé, de l'air frais dédié étant aspiré dans la cartouche de purge et distribué de la cartouche de purge vers le moteur.
