Performance, Combustion and Emission Analysis on A Diesel Engine Fueled with Methyl Ester of Neem and Madhua Oil

One hundred years ago, Rudolf Diesel tested vegetable oil as fuel for his engine. In 1930s and 1940s vegetable oils were used as diesel fuels, but only in emergency situations. Alternative fuels for diesel engines are becoming increasingly important due to diminishing petroleum reserves and the environmental consequences of exhaust gases from petroleum fueled engines. Experimental tests have been carried out to evaluate the performance, emission and combustion characteristics of a diesel engine when fuelled with two different biodiesel (Neem oil MEON, Madhua oil MEOM) and its blends of 20%, 40%, 60%, 80% and 100% of biodiesel with ordinary diesel fuel separately. Tests on ordinary diesel fuel have also been carried out for comparison purposes. The experimental results show that the engine brake thermal efficiency and fuel consumption are comparable to diesel when fueled with two different biodiesel and its blends. The emission of nitrogen oxides (NOx) from biodiesel and its blends are lower than that of pure diesel fuel. Keywords- Biodiesel, Combustion, Emission, Performance, Neem oil, Madhua oil.
