Emission Analysis of Diesel Engine Fuelled with Jatropha Oil Methyl Ester Blends

Abstract

237 In the present era, due to the high brake thermal efficiency of modern diesel engines, the conventional fuel consumption in agricultural sector has increased to an extreme end, which is causing drastic depletion of the natural resources. Due to good oxidation characteristics and lubricating nature, the biodiesel is attracting the world to its side as an alternative fuel. The present paper elaborates the emission characteristics of an agricultural diesel engine utilising jatropha oil methyl ester with diesel blends (B10, B20 and B30). All the emission values were noted and plotted in the graph against loads varying at 0%, 20%, 40%, 60%, 80%, 100%. The results depict that BD20 is the blend, which shows less tendency towards the emissions like CO, CO2, HC, while there is a slight increment in both NOx and smoke emission in comparison to the other test fuel blends, which gives a conclusion that B20 is a best alternative fuel capable of replacing current petroleum diesel fuels to reduce the engine emissions.
