Global dependency and exhaustive usage of fossil fuels is leading to depletion of fossil fuel energy. The exponential rise in energy demand is an alarming sign; and added to that, emission generation, from burning of fossil fuel, has caused adverse effect on the environment. This paves the way in harvesting renewable energy options for a futuristic clean and healthy environment. The potentiality of biodiesel as an alternate energy option is well explored in past couple of decades. However with biodiesel, NO emissions as well as performance of engine from biodiesel is reported to be inferior to that of diesel owing to their inferior physical properties like density and viscosity. The mixture of biodiesels and different types of alcohols neutralizes the inferior property of blends. Ternary or quaternary blends of biodiesel have reported positive engine results. Initially, detailed study of different types of binary blends with respect to performance and emissions is done, trying to identify the research gap with the usage of binary mixture. The paper then dives into detailed study of ternary and quaternary blends with respect to performance, emission and combustion characteristics, trying to highlight different research outcomes.
全球对化石燃料的依赖和广泛使用导致了化石燃料能源的枯竭。能源需求的指数级增长是一个令人担忧的迹象；此外，燃烧化石燃料产生的排放对环境造成了不利影响。这为未来清洁健康的环境开辟了可再生能源选择的途径。在过去几十年中，生物柴油作为替代能源选择的潜力得到了充分探索。然而，由于生物柴油的密度和粘度等物理性质较差，与柴油相比，其 NO 排放和发动机性能较差。生物柴油与不同类型的醇的混合物可以中和混合物的不良特性。三元或四元生物柴油混合物已报告对发动机有积极的效果。最初，针对性能和排放，对不同类型的二元混合物进行了详细研究，试图确定使用二元混合物时的研究差距。然后，本文深入研究了三元和四元混合物的性能、排放和燃烧特性，试图突出不同的研究结果。
