本实验研究了丁醇、戊醇和环戊酮与柴油混合的含氧生物燃料组分的燃烧特性、气体排放和颗粒物（PM）。此外，还研究了PM的尺寸分布、形貌和纳米结构等特性。可持续燃料混合组分（生物醇和生物酮）的氧含量和较低的十六烷值导致了较长的点火延迟，较大的预混燃烧阶段和较高的平均峰值燃烧温度，使颗粒总数浓度降低了91%。颗粒的表征显示了形态和纳米结构的改变，例如初级颗粒尺寸的减小会导致颗粒氧化反应性增强。此外，含氧混合物的燃烧表现出总碳氢化合物排放量的减少和no2浓度的增加。这项研究为了解燃料特性对气体和颗粒排放形成和特征的影响提供了新的知识。总的来说，这项工作证明了生物醇和生物酮作为低碳燃料在揭示汽车减排战略方面的作用。
This experimental work investigates oxygenated bio-fuel component blends of butanol, pentanol and cyclopentanone with diesel on the combustion characteristics, gaseous emissions and particulate matter (PM). Furthermore, PM characteristics, including size distributions, morphology and nanostructure are investigated.The oxygen content on the sustainable fuel blend components (bio-alcohols and bio-ketone) and the lower cetane number leading to a longer ignition delay, larger premixed combustion phase and high mean peak combustion temperature reduced the total number of particle concentration by up to 91%. Characterisation of particles demonstrated morphological and nanostructural alterations, such as the reduction in primary particle size that would lead to greater particle oxidation reactivity. Furthermore, the combustion of oxygenated blends showed a reduction in the total hydrocarbon emissions and an increase in NO2concentration. This research provides new knowledge to understand the effects of fuel properties on gaseous and particle emissions formation and characteristics. Overall this work demonstrates bio-alcohols and bio-ketones as low carbon fuels in unveiling strategies for vehicular emissions abatement.
