Replacement of conventional petroleum jet fuel with sustainable aviation fuels (SAFs) can significantly reduce non-volatile Particulate Matter (nvPM) emissions from aircraft main engines and auxiliary power units (APUs). As part of the Initiative Towards sustAinable Kerosene for Aviation (ITAKA) project, the impact of fuel hydrogen content on nvPM number and mass emissions and particle size distributions were investigated using a GTCP85 APU burning blends of conventional (Jet A-1) and Hydrotreated Esters and Fatty Acids (HEFA)-derived (Used Cooking Oil and Camelina) aviation fuels. The measurements were conducted during two separate test campaigns performed three years apart, each employing a different regulatory compliant sampling and measurement reference system for aircraft engine nvPM emissions. The objective was to investigate the correlation of fuel hydrogen content with nvPM number and mass emissions at the engine exit plane (EEP) independent of fuel composition, measurement system, and ambient conditions. The nvPM number and mass emissions and size distributions systematically decreased with increasing fuel hydrogen content regardless of the fuel composition or APU operating condition. The measured nvPM emissions were particle loss-corrected to the EEP and normalised to a common fuel hydrogen content. Similar rates of nvPM reductions were observed for both test campaigns at all investigated APU operating conditions, confirming that engine exit nvPM reductions correlate with fuel hydrogen content for fuels of relatively similar compositions. This analysis method can be applied to emissions data from other engine types to compare the reduction in nvPM emissions for sustainable aviation fuels and blends.

燃料氢含量对使用标准参考系统测量的飞机辅助动力装置排放的非挥发性颗粒物的影响

用可持续航空燃料(SAF)替代传统的石油喷气燃料可以显着减少飞机主机和辅助动力装置(APU)的不挥发颗粒物(nvPM)排放。作为“朝着可持续的航空煤油计划”(ITAKA)计划的一部分,使用常规(喷射A-1)和加氢处理酯类的GTCP85 APU燃烧混合物研究了燃料氢含量对nvPM数量,质量排放和粒度分布的影响。和脂肪酸(HEFA)衍生的(用于食用油和山茶的)航空燃料。这些测量是在两次间隔三年的独立测试活动中进行的,每项测试活动均针对航空发动机nvPM排放量采用了不同的符合法规的采样和测量参考系统。目的是研究与燃料成分,测量系统和环境条件无关的发动机出口平面(EEP)处燃料氢含量与nvPM数量和质量排放的相关性。随燃料氢含量的增加,nvPM数量,质量排放量和尺寸分布会系统降低,而与燃料成分或APU操作条件无关。将测得的nvPM排放物的颗粒损失校正至EEP,并归一化为普通燃料的氢含量。在所有调查的APU运行条件下,两个测试活动均观察到了相似的nvPM降低率,从而证实了发动机出口nvPM的降低与组成相对相似的燃料的氢含量相关。
