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 CeO₂nanoparticles 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 CeO₂nano additive biodiesel emulsion fuels compared to those of B20.
