代用燃料对发动机测试的影响以及报告规程

[中文适用范围]： 本 SAE 信息报告中的指南针对使用替代燃料的实验室发动机测功机测试程序，适用于四冲程循环火花点火 (SI) 和柴油 (CI) 发动机（自然吸气或压力增压，带或不带充气）空气冷却）。 SAE J1297 中提供了一些替代燃料调查的简要概述。其他涉及车辆、发动机或部件测试的 SAE 文件可能会受到替代燃料使用的影响。一些可能受影响的文件可以在附录A中找到。附录D中为发动机功率测试规范（SAE J1349）提供了指南。这些指南的原则可能适用于其他程序和规范，但影响并没有被调查。该报告分为四个技术部分，每个部分涉及使用替代燃料时测试或结果报告的一个重要方面。第一部分（第 3 节）讨论发动机运行中什么是“燃料”等问题。接下来（第 4 节）涉及识别燃料特性。第三个技术部分（第 5 节）涵盖替代燃料的测试注意事项和计算。最后的技术部分（第 6 节）提供了一些报告结果的指南，以便以方便比较不同调查结果的形式提供足够的信息。 [外文原描述]： The guidelines in this SAE Information Report are directed at laboratory engine dynamometer test procedures with alternative fuels, and they are applicable to four-stroke and two-stroke cycle spark ignition (SI) and diesel (CI) engines (naturally aspirated or pressure charged, with or without charge air cooling). A brief overview of investigations with some alternative fuels can be found in SAE J1297. Other SAE documents covering vehicle, engine, or component testing may be affected by use of alternative fuels. Some of the documents that may be affected can be found in Appendix A . Guidelines are provided for the engine power test code (SAE J1349) in Appendix D . The principles of these guidelines may apply to other procedures and codes, but the effects have not been investigated.The report is organized into four technical sections, each dealing with an important aspect of testing or reporting of results when using alternative fuels. The first ( Section 3 ) deals with such issues as what is a "fuel" in the context of engine operation. The next ( Section 4 ) is concerned with identifying fuel properties. The third technical section ( Section 5 ) covers the testing considerations and calculations for alternative fuels. The final technical section ( Section 6 ) provides some guidelines for reporting the results so that sufficient information is given in a form that allows convenient comparison of the results from different investigations.Cross Reference: ASTM D 909,ASTMD-2P-176,ASTMD1018,ASTMD1072,ASTMD1266/IP107,ASTMD129/IP61,ASTMD1298,ASTMD1405,ASTMD1480,ASTMD1552,ASTMD1685,ASTMD1826,ASTMD2015,ASTMD2382,ASTMD2385,ASTMD240,ASTMD2420,ASTMD2421,ASTMD2504,ASTMD2551,ASTMD2622,ASTMD2623,ASTMD2699,ASTMD2700,ASTMD2725,ASTMD2747,ASTMD2784,ASTMD2785,ASTMD2885,ASTMD2886,ASTMD3031,ASTMD3120,ASTMD3227/IP342,ASTMD3228,ASTMD323,ASTMD3230,ASTMD3235,ASTMD3246,ASTMD3286,ASTMD3343,ASTMD3431,ASTMD3505,ASTMD3588,ASTMD3701/IP338,ASTMD3703,ASTMD4045,ASTMD4046,ASTMD4052,ASTMD4084,ASTMD4175,ASTMD4292,ASTMD4294,ASTMD439,ASTMD445,ASTMD4529,ASTMD56,ASTMD613,ASTMD93,ASTMD976,ASTME147,ASTME148,ASTME191,ASTME258,ASTME379,ASTME711,D909,Fed.
