The present study is to analyze the effect of nano additives of Zinc oxide particles on engine performance and emissions characteristics of a diesel engine fuelled with Jatropha Methyl Ester (J20) as a fuel. The zinc oxide particles such as 50ppm & 100ppm were added to various blends of J20. Results show that addition of zinc oxide additive improves the brake thermal efficiency and is effective in control of hydrocarbon (HC), carbon monoxide (CO), smoke and oxides of nitrogen (NOx) at full load conditions.
