Abstract

In this research, the blends of ethanol and biodiesel with diesel in varying proportions were used. Performance parameters like torque, brake power, brake thermal efficiency and brake specific fuel consumption (BSFC) were studied. The results showed that the BED30 fuel gave the best performance in comparison with conventional diesel fuel. The tests were carried out on a horizontal single-cylinder, 4-stroke, air-cooled, 3.68 kW engine, TecQuipment TD115 MK-II model. The engine was coupled to a manometer (model: Z30EBIX25) and DG eddy current dynamometer (model: WB2.7 PB43) with rated power of 3.68 kW at 2600 rpm and was operated at a constant load of 1000 g. The test results showed that, with decreasing speed, the torque of the engine fueled with both diesel and the blends increased, and the maximum torque was recorded at 1760 rpm of engine speed, for all the fuel samples tested. The research reveals that for a constant load of 1000 g, brake power increases with the increase in engine speed, thus a maximum brake power of 2.4 kW was obtained at 2080 rpm for BED30, this confirmed the results reported by researchers. There was an increase in the engine’s brake thermal efficiency when run on diesel and all the fuel blends at all speed conditions. The BSFC of the blends varied depending on the engine power and speed; therefore, for all the blends and diesel, consumption was high at low speed and vice-versa. All the findings compared favorably with the results of other researchers.
