Effects of nano additives on performance and emission characteristics of a diesel engine fueled with Annona methyl ester

ABSTRACT

The aim of 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 Annona methyl ester (A20) as a fuel. The zinc oxide particles was added to various blends of A20 such as 80% diesel + 20% Annona methyl ester, 80% diesel + 20% Annona methyl ester + 50 ppm zinc oxide particles, 80% diesel + 20% Annona methyl ester + 50 ppm zinc oxide. The AME (A20) was mixed with zinc oxide particles with the aid of a ultrasonicator. Results show that addition of zinc oxide additive improves the brake thermal efficiency (BTE) and reduces specific fuel consumption at full load conditions. The zinc oxide additive is effective in control of hydrocarbon (HC), carbon monoxide (CO), smoke and oxides of nitrogen (NO_x) at full load conditions.
