PERFORMANCE AND EMISSION CHARACTERISTICS OF DIESEL ENGINES WITH Al2O3 AND CuO NANOPARTICLES AS ADDITIVES

This main objective of this paper is to check the suitability of nanodiesel as CI engine fuel. Experiments are conducted on four stroke, single cylinder CI engine with diesel and nanodiesel. Two nanodiesels diesel+Al2O3 and diesel+CuO are chosen for study at the fixed concentration of 0.006% by wt. The effect of addition of nanoparticles on engine performance and exhaust emissions are studied. Among all the fuels Al2O3 nanodiesel exhibits better performance. The participation of nanoparticles in combustion enhances the engine performance and reduces the CO, HC & NOx emissions. Due to addition of nanoparticles, BSFC is reduced by 1.4% for Al2O3 nanodiesel and 0.65% for CuO nanodiesel. Further, by using Al2O3 nanodiesel, HC, CO and NOx emissions are reduced by 13.3%,12.17% and 8.75%, respectively whereas for CuO nanodiesel HC,CO and NOx emissions reduction is limited to 6.3%,7.11% and 2.6%, respectively.
