Performance testing of moringa oleifera seed oil biodiesel with additives in diesel engine

Now a day's liquid biodiesel fuels utilization that are produced from renewable natural resources such as moringa oleifera seeds using transesterification method accounts among the best alternative option for substituting conventional fossil fuels. This investigation shows production of biodiesel from moringa oleifera seeds by transesterification process with an additive of diethyl ether (DEE2%). It also finds out the efficiency and emission analysis of three fuels namely pure diesel, B20 (20% moringa blended with 80% diesel), and B20DEE2% (20% Moringa &2%DEE additive blended with 78% diesel) compression ignition engine using single cylinder, 4-stroke direct injection method. The observations of the fuel characterization show that B20 and B20DEE2% biodiesel blended fuels have nearly equal characteristics such as viscosity, density, and calorific values that compared to diesel fuel. Moreover, these fuels have comparable performance such as brake thermal efficiency, brake power, brake torque, and specific fuel consumption compared to clear diesel fuel, and especially B20DEE2% have better emission condition than B20 biodiesel blend fuel.
