Abstract
This work investigates the detailed study on emission characteristics of compression ignition engine fuelled with diesel, mahua oil biodiesel (MOBD) and cerium oxide nanoparticle (CeO2). Cerium oxide nanoparticles were mixed with neat mahua oil methyl ester (MOME) at a different dose of 100 and 200 ppm on a mass basis. Experimental results revealed that nanoparticle had a positive effect on emissions of MOME. CeO2 nanoparticle acts as an oxygen shelter owing to its high surface energy content due to its huge surface to volume ratio that expedites the process of combustion. Among the fuels containing CeO2 nanoparticles, MOBDCeO2200 showed an improvement in various emissions as compared to conventional fuels. CeO2 nanoparticles were the superior oxidising catalysts as they could effectively reduce HC and CO emissions. NOx emission reduced substantially due to catalytic activity of CeO2 nanoparticles.
