Abstract
Abstract Calcium oxide nanoparticles obtained from biowaste through calcination process is used as nanoadditives in the blend of B20 (80%Diesel + 20%Waste cooking oil biodiesel). Performance and emission characteristics are examined for single cylinder four stroke, diesel engine connected to eddy current type dynamometer for loading. B20 blend of Waste cooking oil biodiesel is doped with calcium oxide nano particles in 5 quantities as 25 ppm, 50 ppm, 75 ppm, 10 ppm, and 125 ppm. Diesel has high brake thermal efficiency values among all the fuels blends with 125 ppm CaO nano additives. Diesel has the lowest NOx emissions and the blend with 125 ppm Cao Nano additives produced less NOx values among the blends. Carbon emissions are comparatively lesser for the biodiesel blends compared to diesel.
