Abstract: | An investigational research is carried out to found the performance and emission characteristics of a direct injection (DI) diesel engine with cerium oxide nanoparticles additives in diesel and biodiesel blends. Mahua methyl ester was produced by transesterification and blended with diesel. Cerium oxide nanoparticles of 50 and 100?ppm in proportion are subjected to high-speed mechanical agitation followed by ultra-sonication. The experimentations was conducted on a single cylinder DI diesel engine at a constant speed of 1500?rpm using different cerium-oxide (CeO2)-blended biodiesel fuel (B20?+?50?ppm, B20?+?100?ppm, B50?+?50?ppm and B50?+?100?ppm) and the outcomes were compared with those of neat diesel and Mahua biodiesel blend (B20 and B50). The experimental results indicated that brake thermal efficiency of B20?+?100?ppm cerium oxide was increased by 1.8 with 1% betterment in specific fuel consumption. Emissions of hydrocarbon and carbon monoxide were reasonably lower than Diesel fuel. |
