这项研究旨在开发未来的替代燃料，重点研究燃料的分子结构对其在先进推进系统中的性能和性能的影响。考察了丁醇、戊醇、环戊醇、环戊酮、汽油等生物质衍生含氧替代燃料及其与柴油混合燃料的摩擦学性能。使用高频往复试验机(HFRR)进行了润滑性试验。与使用它们的整齐形式相比，环戊酮-柴油和环戊醇-柴油混合物的磨痕尺寸更小。在HFRR试验中，被替代燃料污染的下部钢盘导致磨损表面粗糙度比纯柴油低20%。认为这些还原主要是由于醇和酮中分别存在羟基和羰基，使它们更具极性，从而有助于在滑动过程中在磨损的运动表面上形成保护性润滑膜。总体而言，这项研究的结果表明，环境友好型环戊醇和环戊酮是未来先进推进系统实用和高效的候选燃料。
This study relates to developing future alternative fuels and focuses on the effects of a fuel’s molecular structure on its properties and performance in advanced propulsion systems. The tribological performance of various biomass-derived oxygenated alternative fuels, including butanol, pentanol, cyclopentanol, cyclopentanone, and gasoline and their blends with diesel, was investigated. Lubricity tests were conducted using a high-frequency reciprocating rig (HFRR). Cyclopentanone-diesel and cyclopentanol-diesel blends result in smaller wear scar sizes compared to using their neat forms. A lower steel disc contaminated with the alternative fuels during the HFRR tests resulted in worn surface roughness values lower than those of the neat diesel by up to 20%. It is believed that these reductions are mainly due to the presence of the hydroxyl group and the carbonyl group in alcohols and ketones, respectively, which make them more polar and consequently helps the formation of the protective lubrication film on the worn moving surfaces during the sliding process. Overall, the results from this study indicate that environmentally friendly cyclopentanol and cyclopentanone are practical and efficient fuel candidates for future advanced propulsion systems.
