As an alternative fuel for the compression ignition engine, the biodiesel blended with diesel at low ratios is a widespread practice that alleviates exhaust emissions and aids in managing the fossil fuel crisis. However, deterioration in performance and combustion with an upsurge in the NOx emissions restrict the application of a higher ratio or pure biodiesel. Hence, this analysis aims to examine and combine distinctive benefits associated with different additives in a blend with biodiesel for maximum replacement of diesel. Maintaining one-half (50% (v/v) of diesel ratio fixed, various combinations of Bael (Aegle marmelos) seed oil biodiesel (B), and additives: Graphene nanosheets (GN), oxygenated diethyl ether (DEE in % v/v) are prepared and tested. The experimentation carried out in two phases, 1) finding the optimum blend (biodiesel-additives) and 2) investigating the performance and emission characteristics of the engine fueled by blends in comparison to diesel. The new additive GN is synthesized using a facile and greener method at room temperature. Results revealed that the blend comprising of biodiesel with dual additives shows improved performance and emission characteristics compared to without additives, any single additive, and pure diesel. The optimum improvement of CO by 41%, NOx by 13.5%, particulates by 45%, UHC by 39%, peak BTE by 3%, BSFC by 5.5% found with the optimum blend (D50+ B35+ GN100 ppm+DEE15). Hence, half of the diesel replaced by the optimum combination, besides a significant positive effect on the atmosphere.

作为压燃式发动机的替代燃料，低比例混合柴油的生物柴油是一种广泛的实践，它可以减轻废气排放并有助于解决化石燃料危机。然而，随着NOx排放量的增加，性能和燃烧的恶化限制了更高比例或纯生物柴油的应用。因此，该分析旨在检查并结合与生物柴油共混物中与不同添加剂相关的独特优势，以最大程度地替代柴油。保持一半（50％（v / v）的柴油比例固定不变，Bael（Aegle marmelos）种子油生物柴油（B）和添加剂的各种组合：石墨烯纳米片（GN），氧化二乙醚（DEE，以％v / v）准备并测试，实验分两个阶段进行，1）找到最佳的混合气（生物柴油添加剂），2）研究与柴油相比，混合气为燃料的发动机的性能和排放特性。新添加剂GN是在室温下使用简便且绿色的方法合成的。结果表明，与不含添加剂，任何单一添加剂和纯柴油的生物柴油相比，包含生物柴油和双重添加剂的共混物具有改善的性能和排放特性。使用最佳掺混物（D50 + B35 + GN100 ppm + DEE15），发现CO的最佳改善量为41％，NOx的浓度为13％，UHC的浓度为39％，BTE的峰值为3％，BSFC的最佳浓度为5.5％。因此，除了对大气的显着积极影响外，一半的柴油被最佳组合所替代。
