Abstract: Continuous rise in the conventional fuel prices and shortage of its supply have increased the interest in the field of the alternative sources for petroleum fuels. In this present work, experimentation was carried out to study the performance and emission characteristics of mahua oil and ethanol blends. For this experiment a single cylinder, four stroke, air cooled diesel engine was used. Initially the engine was run on diesel fuel and the readings were recorded. Then the engine was run on mahua oil and its different blends with ethanol. The blends containing 5, 10 and 15 percent ethanol fuel by volume were denoted as M5, M10 and M15 respectively. The tests were carried out over entire range of engine operation at varying conditions of load. The engine performance parameters studied were brake horse power, brake specific fuel consumption and brake thermal efficiency. The emission characteristics studied are CO, HC, CO2 and smoke opacity. Brake thermal efficiency is high at low and medium loads. For M5 there is 5.1% increase in brake thermal efficiency compared to diesel at low loads. From emission of blends, it is found that HC reduces 11%, CO and smoke decreases by 19% and 33.7% when compared to those of diesel. The present experimental results show that mahua oil and ethanol blends can be used as an alternative fuel in diesel engine.
