In day-to-day life, fossil fuels play an important role in transportation and power generation. The consumption of fossil fuels increasing rapidly with increase in emission from engines. Due to habituation over fossil fuel, both the economy and environment are suffering. The researchers are in the position to find the best alternative for fossil fuels. The employment of biodiesel is taken to be the classy replacement for this snag. According to scores of research, using additions of nanoparticle is the greatest way to control emissions and improve engine performance. Here the assessment was employed though rice bran (RB) oil, rice bran oil blended with aluminum oxide (RB Al₂O₃), and rice bran oil blended with cerium oxide (RB CeO₂). Rice bran oil is extracted and converted into biodiesel by transesterification process. And the nanoadditives are prepared using the two-step method. The addition of nanoadditives showed an improved performance in the engine as well as emission parameters. The congruent assessment clearly demonstrates the improvement of brake thermal efficiency by around 28% for RB-Al₂O₃ and an improved brake-specific fuel of 16%. Both the blends exhibit good part loading traits.

纳米添加剂改善米糠油内燃机性能和排放特性

在日常生活中，化石燃料在交通和发电方面发挥着重要作用。随着发动机排放量的增加，化石燃料的消耗量迅速增加。由于对化石燃料的习惯，经济和环境都受到了影响。研究人员能够找到化石燃料的最佳替代品。生物柴油的使用被认为是解决这一问题的最佳替代品。根据多项研究，添加纳米颗粒是控制排放和提高发动机性能的最佳方式。此处采用米糠油 (RB)、掺有氧化铝的米糠油 (RB Al ₂ O ₃ ) 和掺有氧化铈的米糠油 (RB CeO _{2 )进行评估}). 米糠油通过酯交换过程被提取并转化为生物柴油。纳米添加剂采用两步法制备。纳米添加剂的添加显示了发动机性能和排放参数的改进。_{一致的评估清楚地表明，RB-Al 2} O ₃的制动热效率提高了约 28% ，制动专用燃料提高了 16%。两种共混物都表现出良好的部分负载特性。
