This paper presents the results of investigations carried out on performance of biodiesel obtained from Mahua oil and its blends with diesel from 15%, 25%, 35% & 45% by volume for running a diesel engine. The properties of these blends were found to be comparable to diesel and confirming to the American standards. Engine performance, ( brake specific fuel consumption, brake thermal efficiency, total energy consumption& total fuel consumption ) Exhaust Gas Temperature emissions & emissions (CO, HC, NOx & CO2 ) were measured to evaluate and compute the behaviour of the diesel engine running on biodiesel at injection pressures 200 bar & CR 17.5:1. The increase in power output, brake thermal efficiency and reduction in brake specific fuel consumption were observed. Injection pressure and compression ratios were found to have significant effects on engine performance parameters. The power output decreased with increase in the concentration of Mahua methyl ester in diesel. The reductions in exhaust emissions and brake specific fuel consumption together with increase brake power, brake thermal efficiency made the blend of biodiesel in between MB15 to MB25 is found suitable alternative fuel for diesel and thus could help in controlling air pollution.
