An Experimental Investigation on Diesel Engine Performance by the Application of Dual Bio-Diesel Blends

This paper investigates the feasibility of the Biofuel and diesel used in a proportionate mixture as a Biodiesel as a replacement for Diesel fuel. Biodiesel has gained significant attention in the power world as an alternative to biodiesel blends prepared in this study is 50% Neem and 50% Pongamia pinnate. During the study, the blends used for testing were B5%, B10%, B15% and B20% with a varying load condition of 3kg to 20kg in a single-cylinder diesel engine at rpm of 1600 with a load of 19.01kg. A pyrolysis method is used for making Biodiesel. The viscosity values of the Biodiesel blend lie in the range of 3.89 to 8.756 Nm/s. The performance of biodiesel has been analysed in terms of break power, indicated power, break and indicated thermal efficiency, mechanical efficiency, torque, specific fuel consumption, and volumetric efficiency. The parametric value of the all curve shows the increasing behaviour from lower to higher value. Volumetric efficiency shows only decreasing behaviour concerning load. The result shows the B5% blend is better in break power by 13.43% than a diesel at a load of 19.01kg. And specific fuel consumption. The torque generated is more efficient in B20% blends. Break thermal efficiency is proportional to the load of the engine. Indicated Thermal efficiency is much higher than diesel of B5% Biodiesel. The maintenance of a fuel pump is required regularly due to more viscosity problems.
