采用乳化法制备生物质油/柴油混合物并在柴油发动机中燃烧。然后移除注射器，并使用HRTEM、SEM/EDAX、拉曼和XRD的组合来表征针式喷嘴上的碳质沉积物的形态、组成和结构。结果表明，结晶度高的乳化燃料的积炭量大于柴油。柴油和乳化油的积碳颗粒团聚粒径分别约为10-30 μm和50 μm。来自乳化燃料的碳沉积机理归因于基团的高氧含量，导致增加的聚合和随后在喷嘴表面上的冷凝，然后碳化。
A biomass oil/diesel blend was prepared using an emulsion method and combusted in a diesel engine. An injector was then removed and the morphology, composition, and structure of the carbonaceous deposits on the pintle-type nozzle were characterized using a combination of HRTEM, SEM/EDAX, Raman and XRD. Results showed that the carbon deposition of the emulsified fuel with high crystallinity was greater than that of diesel. The agglomerated particulate diameters of the deposited carbon from diesel and emulsified fuel were approximately 10–30 μm and 50 μm, respectively. The carbon deposition mechanism from the emulsified fuel was attributed to the high oxygen content of the groups leading to increased polymerization and subsequent condensation on the nozzle surfaces that was then carbonised.
