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 (Al₂O₃ and Fe₂O₃) 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 Al₂O₃ 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/⁰CA, 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.
