This study investigated the engine performance and emission characteristics of biodiesel blends with combined Graphene oxide nanoplatelets (GNPs) and 10% v/v dimethyl carbonate (DMC) as fuel additives as well as analysed the tribological characteristics of those blends. 10% by volume DMC was mixed with 30% palm oil biodiesel blends with diesel. Three different concentrations (40, 80 and 120 ppm) of GNPs were added to these blends via the ultrasonication process to prepare the nanofuels. Sodium dodecyl sulphate (SDS) surfactant was added to improve the stability of these blends. GNPs were characterised using Scanning Electron Microscope (SEM) and Fourier Transform Infrared (FTIR), while the viscosity of nanofuels was investigated by rheometer. UV-spectrometry was used to determine the stability of these nanoplatelets. A ratio of 1:4 GNP: SDS was found to produce maximum stability in biodiesel. Performance and emissions characteristics of these nanofuels have been investigated in a four-stroke compression ignition engine. The maximum reduction in BSFC of 5.05% and the maximum BTE of 22.80% was for B30GNP40DMC10 compared to all other tested blends. A reduction in HC (25%) and CO (4.41%) were observed for B30DMC10, while a reduction in NO_x of 3.65% was observed for B30GNP40DMC10. The diesel-biodiesel fuel blends with the addition of GNP exhibited a promising reduction in the average coefficient of friction 15.05%, 8.68% and 3.61% for 120, 80 and 40 ppm concentrations compared to B30. Thus, combined GNP and DMC showed excellent potential for utilisation in diesel engine operation.

这项研究调查了混合使用氧化石墨烯纳米片（GNP）和10％v / v碳酸二甲酯（DMC）作为燃料添加剂的生物柴油混合物的发动机性能和排放特性，并分析了这些混合物的摩擦学特性。将按体积计10％的DMC与30％的棕榈油生物柴油混合物与柴油混合。通过超声处理将三种不同浓度（40、80和120 ppm）的GNP添加到这些混合物中，以制备纳米燃料。添加十二烷基硫酸钠（SDS）表面​​活性剂以改善这些混合物的稳定性。使用扫描电子显微镜（SEM）和傅立叶变换红外（FTIR）对GNP进行表征，同时通过流变仪研究纳米燃料的粘度。紫外光谱法用于确定这些纳米片的稳定性。GNP比为1：4：发现SDS在生物柴油中产生最大的稳定性。这些纳米燃料的性能和排放特性已在四冲程压缩点火发动机中进行了研究。与所有其他测试共混物相比，B30GNP40DMC10的BSFC降低幅度最大为5.05％，最大BTE为22.80％。B30DMC10的HC（25％）和CO（4.41％）减少，而NO减少B30GNP40DMC10的_x值为3.65％。与B30相比，添加GNP的柴油-生物柴油燃料混合物显示出120、80和40 ppm浓度的平均摩擦系数有望降低15.05％，8.68％和3.61％。因此，GNP和DMC的组合显示了在柴油发动机运行中利用的极好的潜力。
