Abstract

Se proporciona un vehículo (100). El vehículo (100) comprende un depósito de combustible (130) montado en una pluralidad de rieles de asiento (127, 128) de un bastidor de carrocería (126). El tanque de combustible (130) comprende un sistema de control de emisiones por evaporación (150). El sistema de control de emisiones de evaporación (150) comprende un separador (152) acoplado de forma fluida al depósito de combustible (130). El separador (152) comprende una abertura de ventilación (160). El sistema de control de emisiones de evaporación (150) también comprende al menos dos válvulas de retención (156, 158) provistas en un pasaje de emisión de evaporación (154) que conecta la abertura de ventilación (160) a la atmósfera. Las al menos dos válvulas de retención (156, 158) están configuradas para permitir y restringir selectivamente el flujo de aire desde la atmósfera al tanque de combustible (130) y el flujo de vapor de combustible desde el tanque de combustible (130) a la atmósfera.A vehicle (100) is provided. The vehicle (100) comprises a fuel tank (130) mounted on a plurality of seat rails (127, 128) of a body frame (126). The fuel tank (130) comprises an evaporative emission control system (150). The evaporative emission control system (150) comprises a separator (152) fluidly coupled to the fuel tank (130). The separator (152) comprises a ventilation opening (160). The evaporative emission control system (150) also comprises at least two check valves (156, 158) provided in an evaporative emission passage (154) that connects the vent opening (160) to the atmosphere. The at least two check valves (156, 158) are configured to selectively allow and restrict the flow of air from the atmosphere to the fuel tank (130) and the flow of fuel vapor from the fuel tank (130) to the fuel tank (130). atmosphere.
