Effects of antioxidant additives on exhaust emissions reduction in compression ignition engine fueled with methyl ester of annona oil

Abstract

In this present study, biodiesel is a cleaner burning alternative fuel to the Neat diesel fuel. However, several studies are pointed out that increase in NOx emission for biodiesel when compared with the Neat diesel fuel. The aim of the present study is to analyze the effect of antioxidant (p-phenylenediamine) on engine emissions of a Diesel engine fuelled with methyl ester of annona oil. The antioxidant is mixed in various concentrations (0.010 to 0.040% (w/w)) with methyl ester of annona oil. Result shows that antioxidant additive mixture (MEAO+P200) is effective in control of NOx and HC emission of methyl ester of annona oil fuelled engine without doing any engine modification.
