The present study is dealt with the phenomenon of combustion for rice bran oil (RBO) methyl ester blends with diesel along with nanoparticles of magnelium. Nanoparticles composition of 25 ppm, 50 ppm, and 75 ppm are added to blends of B20, B40, and B60 in the study. A conversion rate of 89.64 ± 2.8% is observed during the transesterification reaction performed at 5 wt% of potassium hydroxide (KOH) catalyst, 10:1 alcohol to oil ratio (methanol), 75 °C reaction temperature, and 60 min reaction time. During the combustion study, few samples displayed the puffing characteristics, which are caused by popping of bubbles at lower pressure. The summary of the present study suggested that blend B20 with 25 ppm nanoparticles has the potential to be used as fuel and further proposed that the fuel will be more economical if the injection droplet diameter is 0.77 mm. Other blends like B20 with 75 ppm are also likely to be used as fuel due to its exhibition of lesser threat towards combustion. Bubble formation followed by micro-explosion is observed in B60 with 25 ppm blend. The present study hoped to enrich future researchers working in similar area for signifying the importance of understanding droplet combustion of biofuels.

本研究研究了米糠油（RBO）甲酯与柴油以及镁纳米颗粒共混物的燃烧现象。在研究中，将25 ppm，50 ppm和75 ppm的纳米颗粒成分添加到B20，B40和B60的混合物中。在以5 wt％的氢氧化钾（KOH）催化剂，10：1的醇与油的比例（甲醇），75°C的反应温度和60分钟的反应时间进行酯交换反应期间，观察到转化率为89.64±2.8％。在燃烧研究期间，很少有样品显示出膨化特性，这是由于低压下气泡爆裂引起的。本研究的总结表明，B20与25 ppm纳米颗粒的共混物具有用作燃料的潜力，并且进一步建议，如果喷射液滴直径为0，则燃料将更加经济。77毫米。由于其对燃烧的威胁较小，其他混合燃料（如B20和75 ppm）也有可能被用作燃料。在掺有25 ppm的B60中观察到气泡形成，然后发生微爆炸。本研究希望丰富未来从事类似领域工作的研究人员，以表明理解液滴燃烧生物燃料的重要性。
