静电学电荷缓解燃料系统和部件

[中文适用范围]： 本 SAE 推荐做法的目的是解释与汽车燃油系统相关的静电荷现象，以及如果出现这些现象应如何处理。本文件仅限于称为燃油系统的组件组，并且仅限于在以下两种情况之一下处理液体燃料的组件：燃油输送系统的操作和车辆加油。这是从文献和演示文稿中总结的想法和一般性的集合，从一些实验室实验中推断出来，并从汽车行业的经验中总结出来，由 SAE 燃油管和配件标准委员会静电小组委员会解释。一些讨论被简化了。如果本文件的使用者需要一些进一步的技术信息，应咨询专家或直接检查此处引用的参考文献。此外，还讨论了一系列可能适用的测试程序。这些程序是测量单个组件或系统的推荐方法，以评估其处理可能出现的静电荷情况的能力。它们并不是唯一可能的测试，但它们已在汽车行业的各个地方用于材料、部件、系统等，并且事实证明，如果遵循得当，可以提供有意义的数据。任何有关特定燃油系统性能的问题都应通过直接测试或涉及系统或单个组件的其他实验来处理。应咨询使用燃油系统的车辆原始设备制造商以获取有关具体要求的信息。本文档可能有助于提供有关如何进行的指南。 [外文原描述]： This SAE Surface Vehicle Recommended Practice deals with electrostatic charge phenomena that may occur in automotive fuel systems and applies to the following:Fuels that are in a liquid state at ambient temperatures and atmospheric pressures and are contained in vehicle fuel tanks that operate at or near atmospheric pressure. This includes gasoline and diesel fuels, as well as their blends with additives such as alcohols, esters, and ethers, whether the additives are petroleum based or bio-fuel based.The group of components that comprise the fuel system (in contact and not in contact with fuels).Other components in proximity to the fuel system that may be affected by electrostatic fields caused by the fuel system.Electrostatic phenomena that arise from, or are affected by, the following aspects of vehicle or fuel system operation:Flowing fuel in the fuel delivery system.Flowing fuel being dispensed to the vehicle while it is being fueled.
