    • A device for a fuel vapor pressure management apparatus of a fuel system supplying fuel to an internal combustion engine. The fuel vapor pressure management apparatus performs leak detection on a headspace of the fuel system, performs excess negative pressure relief of the headspace, and performs excess positive pressure relief of the headspace. The device includes a seal that is deformable between a substantially symmetrically deformed configuration, a generally asymmetrically deformed configuration, and an undeformed configuration. The seal is adapted to cooperatively engage a poppet such that a first arrangement that includes the seal in the substantially symmetrically deformed configuration and the poppet engaging the seal, a second arrangement that includes the seal in the generally asymmetrically deformed configuration and the poppet engaging the seal, and a third arrangement that includes the seal in an undeformed configuration and the poppet being disengaged from the seal. The first arrangement is associated with the performing leak detection, the second arrangement is associated with the performing excess negative pressure relief; and the third arrangement is associated with the performing excess positive pressure relief.
    • 一种用于向内燃机供应燃料的燃料系统的燃料蒸气压力管理装置。 燃料蒸气压管理装置对燃料系统的顶部空间进行泄漏检测,对顶部空间进行过剩的负压释放,并对顶部空间进行过度的正压力释放。 该装置包括可在基本上对称变形的构型,大致不对称变形构型和未变形构型之间变形的密封件。 密封件适于协作地接合提升阀,使得包括基本上对称变形的构造中的密封件和接合密封件的提升阀的第一布置,包括大致不对称变形构造中的密封件的第二布置以及接合密封件的提升阀 以及包括处于未变形构造的密封件并且提升阀与密封件脱离接合的第三布置。 第一布置与执行泄漏检测相关联,第二布置与执行过量的负压释放相关联; 并且第三布置与执行过量的正压力释放有关。

    • A method of rationalizing the functioning of a fuel vapor pressure management system. The fuel vapor pressure management system is in fluid communication with a headspace of a fuel system, and the fuel system supplies fuel to an internal combustion engine of a vehicle. The method includes providing a fuel vapor pressure management apparatus detecting an absence of leaks with respect to the headspace, counting a number of leak detection tests performed by the fuel vapor pressure management apparatus, counting a number of occurrences of the fuel vapor pressure management apparatus detecting an absence of a leak, and evaluating the number of occurrences within a selected number of tests.
    • 一种使燃料蒸汽压力管理系统功能合理化的方法。 燃料蒸汽压力管理系统与燃料系统的顶部空间流体连通,并且燃料系统向车辆的内燃机供应燃料。 该方法包括提供燃料蒸汽压力管理装置,其检测相对于顶部空间的泄漏的不存在,计算由燃料蒸气压力管理装置进行的泄漏检测试验的次数,计算燃料蒸气压力管理装置检测的次数 没有泄漏,并且在所选数量的测试中评估出现的次数。
