Performance, combustion and emission characteristic of a marine engine running on grape seed oil biodiesel blends with nano additive

Abstract

Present study provides the effect of Cerium Oxide (CeO2) nano fuel additives on the performance, combustion and emission characteristics of a Grape Seed Oil Methyl Ester (GSOME). Biodiesel blended fuel is prepared by the emulsification technique with the aid of a mechanical agitator. Prepared biodiesel emulsion fuels were mixed with the CeO2 nanoparticles in the mass fractions of 50 and 100 ppm with the help of an ultrasonicator. Fuel properties of B20 (80% Diesel + 20% GSOME), B20CeO250 (80% Diesel + 20% GSOME + 50ppm CeO2), B20CeO2100 (80%Diesel + 20% GSOME + 100ppm CeO2) and neat biodiesel were studied and compared according to ASTM standard test methods for biodiesel. Study is carried out at a constant speed of 1500rpm. Experimental results show a significant improvement in the performance and a reduction in harmful emissions for the CeO2 nano additive biodiesel emulsion fuels compared to those of B20.
