This research work aims to investigate the effect of fuel-borne additives when added to mahua methyl ester (MME) blend operated on common rail direct injection diesel engine. Nanoparticles (AlO and FeO) were chosen with the help of a homogenizer and ultrasonicator as fuel additives at dosing levels of 40, 80, and 120 ppm, respectively, and the biodiesel is prepared by blending 80% diesel and 20% MME. The performance, emission, and combustion characteristics were considered for analysis. The experimental study revealed that while using the AlO nanoparticle additives' blended biodiesel (MME20+AONP120), the number of harmful pollutants like smoke (5.38%), HC (6.39%), carbon monoxide (10.24%), NOx, etc. has reduced to a considerable extent and there was a commendable improvement in the BTE by 8.8% in comparison with MME20. Moreover, MME20+AONP120 blend resulted in high in-cylinder pressure, HRR of about 58.4 bar, and 118 J/CA, respectively, which are higher than diesel and MME20. So, it can be summarized that when biodiesel and nano additives are blended together, the combustion and performance of the engine were improved considerably and pollutant emissions were decreased.
这项研究旨在探讨燃油添加剂在掺用麻疯树甲酯（MME）的共轨直喷式柴油机中的作用。在均化器和超声仪的帮助下，选择纳米颗粒（AlO 和 FeO）作为燃料添加剂，剂量水平分别为 40、80 和 120ppm，并制备 80%柴油和 20%MME 的生物柴油。考虑了性能、排放和燃烧特性进行分析。实验研究表明，在使用掺有 AlO 纳米颗粒添加剂的生物柴油（MME20+AONP120）时，烟雾（5.38%）、HC（6.39%）、一氧化碳（10.24%）等有害污染物的数量大大减少，与 MME20 相比，BTE 提高了 8.8%。此外，MME20+AONP120 混合物在缸内产生了较高的压力、较高的 HRR（约 58.4 巴）和 118 J/CA，分别高于柴油和 MME20。因此，可以总结出，当生物柴油与纳米添加剂混合使用时，发动机的燃烧和性能得到了显著改善，同时减少了污染物的排放。
