Biodiesel has been renowned as potential and alternative fuel for years. In order to improve the quality of the conventional fossil fuels, biodiesel, and air pollution from combustion, additives are essential to exploit. In this study, the uses of cerium oxide (CeO₂) nanoparticle additive for B20 fuel in a diesel engine are investigated. The CeO₂ nanoparticles with cetyl-trimethyl ammonium bromide are doped into the B20 fuel by using ultrasonicator. The purpose of the experimental work was adopted to enhance engine combustion and reduce the emissions with an approach of CeO₂ nanoparticle additive. The experiment was conducted on a diesel engine using different propagation of CeO₂ nanoparticle in blended mahua methyl ester fuel such as B20 + CeO₂ 50 ppm, B20 + CeO₂ 100 ppm, and B20 + CeO₂ 150 ppm. The obtained results are compared with the diesel and B20 fuels. The minor changes are obtained in B20 fuel properties due to the addition of CeO₂ nanoparticles. The performance of brake thermal efficiency and combustion of pressure data is observed to be enhanced by the addition of a metal-based additive. The CO, HC, and smoke are decreased for B20 fuel with nanoparticles. The NOₓ is reduced by dosing the CeO₂ due to the oxidation of unburned CeO₂ in the exhaust.
