在单个气缸恒式柴油发动机中，在实验中研究了使用氧化葡萄（CEO2）纳米颗粒作为柠檬油（LGO）乳液燃料添加剂的结果。该项目引入了一种新型的生物燃料植物，即柠檬草，其二项式名称是cymbopogon flexuosus。该项目的主要目的是降低排气中有害污染物的水平，例如未燃烧的碳氢化合物（HC），一氧化碳（CO），氮（NOX）和烟雾的氧化物。由于添加了CEO2纳米颗粒，也可以提高发动机性能。按照5％的水，93％的LGO和SPAN80的2％，制备了LGO乳液燃料。 SPAN80充当表面活性剂，它将减少亲水性 - 亲脂平衡（HLB）值4.2的液体之间的表面张力。将纳米粒子散布在30 ppm（ppm）的剂量中。将柴油发动机性能，燃烧行为和发射幅度与柴油和LGO作为基础燃料进行了比较。整个研究是使用以下燃料的单个气缸柴油发动机进行的，即分别整洁的柴油，整洁的LGO，LGO乳液和LGO纳米乳液燃料。 LGO乳液燃料可以减少烟雾和NOX排放，并可以提高制动热效率（BTE），制动特定能量消耗（BSEC），尽管HC和CO排放率略有增加，但与整洁的LGO相比。对于陶瓷纳米颗粒混合测试燃料，一氧化碳（CO）的急剧减少，未燃烧的烃（HC），氮（NOX）的氧化物（NOX）（NOX）和烟雾不透明的边际减少，与LGO乳液和各种电力燃料相比，可以实现输出。与整洁的LGO和LGO乳液燃料相比，由于CEO2纳米粒子的较大表面积与体积比，液体液体乳液测试燃料的改善还可以改善BTE。 （c）2016 Elsevier Ltd.保留所有权利。
The consequence of using cerium oxide (CeO2) nanoparticle as additive in Lemongrass Oil (LGO) emulsion fuel was experimentally investigated in a single cylinder, constant speed diesel engine. A novel biofuel plant was introduced in this project, namely lemongrass whose binomial name is Cymbopogon flexuosus. The main objective of the project is to reduce the level of harmful pollutants in the exhaust such as unburned hydrocarbon (HC), carbon monoxide (CO), oxides of nitrogen (NOx), and smoke. The engine performance could also be increased due to the addition of CeO2 nanoparticle. The LGO emulsion fuel was prepared in the proportion of 5% of water, 93% of LGO and 2% of span80 by volume basis. Span80 acted as surfactant and it would reduce surface tension between the liquids with a hydrophilic-lipophilic balance (HLB) value of 4.2. The ceria nanoparticle was dispersed with the LGO emulsion fuel in the dosage of 30 ppm (ppm). The diesel engine performance, combustion behavior and emission magnitude were compared with diesel and LGO as the base fuels. The whole investigation was conducted with a single cylinder diesel engine using the following fuels, namely neat diesel, neat LGO, LGO emulsion and LGO nano emulsion fuels respectively. The LGO emulsion fuel could reduce smoke and NOx emissions and could improve Brake Thermal Efficiency (BTE), Brake Specific Energy Consumption (BSEC) compared with neat LGO despite the marginal increase in HC and CO emissions. For ceria nanoparticle blended test fuel, the drastic reduction of carbon monoxide (CO), unburned hydrocarbon (HC), oxides of nitrogen (NOx) and marginal decrease of smoke opacity emission could be achieved compared with the LGO emulsion and diesel fuel at various power outputs. Improvement in BTE was also observed for LGO nano emulsion test fuel compared to neat LGO and LGO emulsion fuels due to improved atomization and rapid evaporation rate of fuel owing to large surface area to volume ratio of CeO2 nanoparticle.
