Abstract
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 50ppm, B20 + CeO2 100ppm, and B20 + CeO2 150ppm. 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.
