Rising fuel costs, an increasing desire to enhance security of energy supply, and potential environmental benefits have driven research into alternative renewable fuels for commercial aviation applications. This paper reports the results of the first measurements of particulate matter (PM) emissions from a CFM56-7B commercial jet engine burning conventional and alternative biomass- and, Fischer-Tropsch (F-T)-based fuels. PM emissions reductions are observed with all fuels and blends when compared to the emissions from a reference conventional fuel, Jet A1, and are attributed to fuel properties associated with the fuels and blends studied. Although the alternative fuel candidates studied in this campaign offer the potential for large PM emissions reductions, with the exception of the 50% blend of F-T fuel, they do not meet current standards for aviation fuel and thus cannot be considered as certified replacement fuels. Over the ICAO Landing Takeoff Cycle, which is intended to simulate aircraft engine operations that affect local air quality, the overall PM number-based emissions for the 50% blend of F-T fuel were reduced by 34 ± 7%, and the mass-based emissions were reduced by 39 ± 7%.
燃料成本上升、增强能源供应安全性的愿望日益强烈以及潜在的环境效益推动了对商业航空应用替代可再生燃料的研究。本文报告了首次测量 CFM56-7B 商用喷气发动机燃烧传统和替代生物质和费托（F-T）基燃料的颗粒物（PM）排放的结果。与参考常规燃料 Jet A1 相比，所有燃料和混合物的 PM 排放量均有所减少，这归因于与所研究的燃料和混合物相关的燃料特性。尽管本研究中使用的替代燃料候选物具有大幅减少 PM 排放的潜力，但除了 50%的 F-T 燃料混合物外，它们不符合航空燃料的现行标准，因此不能被视为经过认证的替代燃料。在国际民航组织着陆起飞循环中，该循环旨在模拟影响当地空气质量的飞机发动机操作，50%的 F-T 燃料混合物的整体基于 PM 数量的排放量减少了 34%±7%，而基于质量的排放量减少了 39%±7%。
