Title (EN) ELECTRONIC FUEL TANK SYSTEM VENTING CONFIGURATION
(FR) CONFIGURATION DE VENTILATION DE SYSTÈME DE RÉSERVOIR DE CARBURANT ÉLECTRONIQUE
Abstract:
(EN) An evaporative emissions control system configured to recapture and recycle emitted fuel vapor on a vehicle fuel tank includes a liquid trap, a first vent tube, a second vent tube and a check valve. The first vent tube is disposed in the fuel tank and extends between a first vent opening and the liquid trap. The second vent tube is disposed in the fuel tank and has a p-trap disposed therein. The second vent tube has a first decreasing elevation portion from the second vent opening to the p-trap and the second increasing elevation portion from the p-trap to the liquid trap. The check valve is disposed at the p-trap trap and is configured to seal the second vent tube when liquid fuel rises above the p-trap and open when liquid fuel recedes below the p-trap.
(FR) La présente invention concerne un système de contrôle des émissions de vapeur configuré pour recapturer et recycler la vapeur de carburant émise sur un réservoir de carburant de véhicule qui comprend un piège à liquide, un premier tube d’aération, un deuxième tube d’aération et un clapet antiretour. Le premier tube d’aération est disposé dans le réservoir de carburant et s’étend entre une première ouverture d’aération et le piège à liquide. Le deuxième tube d’aération est disposé dans le réservoir de carburant et comporte un piège P disposé dans celui-ci. Le deuxième tube d’aération comporte une première partie d’élévation décroissante depuis la deuxième ouverture d’aération s’ouvrant sur le piège P et la deuxième partie d’élévation croissante du piège P au piège à liquide. Le clapet antiretour est disposé au niveau du piège P et est configuré pour sceller le deuxième tube d’aération lorsque le combustible liquide s’élève au-dessus du piège P et s’ouvrir lorsque le combustible liquide recule au-dessous du piège P.
