An environmental effect of GSO methyl ester with ZnO additive fuelled marine engine

Present study provides the effect of Zinc Oxide (ZnO) nanoparticle fuel additives on the performance 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 ZnO nanoparticles in the mass fractions of 50 and 100 ppm with the help of an ultrasonicator. Fuel properties of D80B20 (80% Diesel + 20% GSOME), D80B20ZnO50 (80% Diesel + 20% GSOME + 50 ppm ZnO nano particles) and D80B20ZnO100 (80% Diesel + 20% GSOME + 100 ppm ZnO nano particles) were analyzed and compared according to ASTM standard test methods for biodiesel. Tests were performed at a constant speed of 1500 rpm. Acquired data were studied for various parameters, such as Brake Power (BP), Brake Thermal Efficiency (BTE), Brake Specific Fuel Consumption (BSFC), Exhaust Gas Temperature (EGT), exhaust emission of Carbon monoxide (CO), Hydrocarbon (HC), Carbon dioxide (CO2), Oxides of nitrogen gases (NOx) and smoke density.
