EXPERIMENT ON MULTI BLEND BIODIESEL USING JATROPHA AND PONGAMIA BIODIESEL ON SINGLE CYLINDER DIESEL ENGINE WITH BASE LINE OF DIESEL FUEL

The recent research on biodiesel focused on performance of single biodiesel and its blends with diesel. The present work aims to investigate the possibilities of the application of mixtures of two biodiesel and its blends with diesel as a fuel for diesel engines. The present investigations are planned after a thorough review of literature in this area. The combinations of jatropha biodiesel, Pongamia biodiesel, along with diesel (JPD) are taken for the experimental analysis. Experiments are conducted using a single cylinder direct-injection diesel engine with different loads at rated 1200 rpm. Brake thermal efficiency is increasing of JPD-2 has maximum at (28.5%) compare to pure diesel at (27.5%) at 4 kW. Maximum SFC is obtained in JPD-5 (0.77) at 1 kW. The results which obtained are significantly comparable to pure diesel. The multi-blend biodiesels are suitable alternative fuel for diesel in stationary/agricultural diesel engines.
