Performance & Emissions Characteristics of a Four Stroke Diesel Engine Fuelled With Different Blends of Ankola Oil with Diesel

The uses of biodiesel are increasingly popular because of their low impact on environment. However, it causes combustion problems in conventional diesel engine. The vegetable oils were not acceptable in diesel engine because it poses problems such as injector choking, cylinder deposits, piston ring sticking and higher smoke emissions. Biodiesel has become more attractive recently because of its environmental benefits. ethyl ester of ankola oil is derived through transesterification process. The biodiesel can be used in diesel engine without major hardware modifications. Experimental investigations have been carried out to examine the properties, performance and emission of different blends (B10, B20, B30, and B40) of ankola oil methyl ester in comparison to diesel. Results indicate that B20 is an optimum fuel blend in terms of better performance and reduced emission than diesel fuel. However, B20 blend shows reasonable efficiencies, lower smoke, CO and HC emission.
