Performance Evaluation and Emission Testing of Sea Mango Seeds Oil Biodiesel Blends in CI Engine

Petroleum based fuels worldwide have not only resulted in the rapid depletion of conventional energy sources, but have also caused severe air pollution. The search for an alternate fuel has led to many findings due to which a wide variety of alternative fuels are available at our disposal now. The existing studies have revealed the use of vegetable oils for engines as an alternative for diesel fuel. However, there is a limitation in using straight vegetable oils in diesel engines due their high viscosity and low volatility. In the present work, Sea Mango seed oil is converted into their respective methyl ester through transesterification process. Experiments are conducted using various blends of Biodiesel of sea mango seed oil with diesel in a single cylinder, four stroke vertical and air cooled Comet diesel engine. The experimental results of this study showed that the Sea Mango biodiesel Blends has similar characteristics to that of diesel. The brake thermal efficiency, BSFC, Volumetric efficiency and Emissions are observed to be lower in case of biodiesel blends than diesel. The tests for B00, B10, B50, B90 and B100 are carried by varying load. Analysis showed that B50 blend give better results than other blends. From this study, it is concluded that optimized blend is B50 and could be used as a viable alternative fuel in single cylinder direct injection diesel engine without any modification.
