Abstract
In this experimental study an attempt is made to find out a biodiesel, whose NOx and CO2 emissions are less and encouraging. Vegetable oils namely Babul oil (Acacia Arabica), Tung Oil (Aleurites fordii) and Grape seed oil (vitis vinifera) were transesterified to reduce their viscosity. These biodiesels were studied as fuel in direct injection 3.7 kW, 1500 rpm with electrical resistance loading. Experiments were conducted at constant speed of 1500 rpm at different percentages of full load of the engine. Out of these three, Grape seed oil methyl ester (GSME) has its performance closer to that of diesel fuel followed by Babul Oil Methyl Ester (BOME) and Tung Oil Methyl Ester (TOME). The brake thermal efficiency of GSME is marginally lower than that of Diesel at full load. The CO2 emissions of these biodiesels were 13%, 17% and 29% lower than that of diesel fuel emissions at full load for BOME, GSME and TOME respectively. The NOx emissions of BOME and TOME were lower by 22% and 27% lower than that of diesel fuel. However the smoke emissions are higher than that of pure diesel operation of the engine.
