本技术报告介绍了欧洲未来无铅汽油和汽油混合料的测试方法和要求的概述和时间计划。这意味着乙醇/含氧化合物含量高于燃料质量指令附录I [4]中允许的无铅汽油，其为含有高达3,7％（m/m）氧气的汽油，更熟悉的称为E10。 可能适用于某些水平或类型的含氧化合物的具体问题在本报告的适当部分酌情加以强调。本报告未考虑与专门设计用于在E10以上更广泛的含氧化合物含量范围内运行的车辆相关的所有问题，例如高达E85。 该报告涵盖了E10能源（无发动机效率增益）和E10优化（发动机效率增益）的燃料和车辆概念。 注1:随着含氧化合物的可能组合和水平的增加，该工作着重于标称乙醇含量在10％（V/V）至25％（V/V）之间的无铅汽油。一旦乙醇高于约20％至25％（取决于车辆），可能需要更多的发动机和车辆措施。 注2:为了本文件的目的，术语“％（m/m）”和“％（V/V）”用于表示质量分数

This Technical Report presents an overview and time plan for test methods and requirements that could be expected for future unleaded petrol and petrol blends in Europe. This means unleaded petrol with an ethanol/oxygenates level higher than allowed in the Fuels Quality Directive, Annex I [4], which is petrol containing up to 3,7 % (m/m) of oxygen, more familiarly known as E10. Specific issues that may apply for certain levels or types of oxygenates are highlighted where appropriate in the appropriate sections of this report. This report does not take into account all issues related to vehicles that are specially designed to run on a much wider range of oxygenate contents above E10+, for example up to E85. The report covers fuels and vehicle concepts for both E10+-capable (without engine efficiency gains) and E10+-optimised (with engine efficiency gains). NOTE 1 Following the large possible combinations and levels of oxygenates, the work focuses on unleaded petrol with a nominal ethanol content between 10 % (V/V) and 25 % (V/V). Once the ethanol is higher than approximately 20 % to 25 % (depending on the vehicle) more engine and vehicle measures would likely be needed. NOTE 2 For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent the mass fraction, µ, and the volume fraction, φ, respectively. NOTE 3 Although EN 228 speaks about and defines "unleaded petrol", the wording "petrol" is used throughout this document for the sake of readability.
