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.
