This paper reports on the effect of nanoparticles as additive to the biodiesel blend fuel and its effects on a single cylinder CRDI diesel engine coupled with a data acquisition system. Mahua methyl ester at the ratio of 20% (MME20) taken as fuel for diesel engine. Aluminium oxide (AONP) and Iron oxide (IONP) nanoparticles are used as catalyst with MME20. The nanoparticles added to MME20 in different proportions (40ppm and 80ppm) using an ultrasonicator and a mechanical homogenizer. The

It was observed significant improvement in brake thermal efficiency and heat release rate due to the influence of the nanoparticles addition in MME20 fuel. It was observed that nanoparticles blended fuel exhibits a significant reduction in specific fuel consumption and exhaust emissions at all operating loads.
