Performance study of Neem/Soyabean biofuels on 4-stroke diesel engine

Abstract

The transition from the use of fossil fuel to the latest renewable energy sources, it is need to concentrate on the global energy crisis and their environmental issues. In the present work the Neem and Soya bean methyl ester were used in diesel as a blended fuel. The experimental investigations were carried out in a single cylinder 4-stroke water cooled diesel engine developing 3.7 kW at 1500 RPM. The engine was coupled to a rope brake dynamometer to measure the output, fuel flow rates were timed with calibrated burette. The blends of B10, B15, and B20 of Methyl Ester of Neem and Soyabean methyl ester diesel blends are prepared by volume basis and used for experimental purpose. The engine was loaded with 1.5 kg, 3 kg and 4.5 kg. The engine speed, fuel consumption was recorded. Various performance parameters were evaluated such as BTE, BSFC, and mf. The Study showed that using 100% Diesel, the brake thermal efficiency decreases compared to base engine whereas Brake Specific fuel Consumption increases. The B15 blend of Neem methyl ester yields the best blend with diesel and showed better results for Brake Thermal Efficiency, Brake Specific Fuel Consumption.
