Experimental investigation on the performance and emissions of a diesel engine fuelled with butea monosperma biodiesel and its blend with conventional diesel oil

In this study, the performance and emission characteristic tests have been carried out on a single cylinder direct injection diesel engine running under constant speed and variable Brake power. In this study, the engine tests have been conducted with Butea monosperma oil methyl ester (B100) and their blends with conventional diesel oil in the proportions of 10:90 (B10), 20:80 (B20) and 50:50 (B50). A series of tests have been conducted for each of test fuel. The engine is allowed to run at constant speed at 1500RPM, but at different BP (1, 2, 3, 4 and 5kW). The performance and emission characteristics of blends are analyzed and compared with conventional diesel oil. The experimental results obtained for BMSOME are comparable with conventional diesel oil with the increase in engine performance and reduction in engine exhaust emissions.
