Emission characteristics study of compression ignition engine fuelled with biodiesel and cerium oxide nanoparticle blends

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. NO_x emission reduced substantially due to catalytic activity of CeO₂ nanoparticles.
