Paper Title
Performance of DI Diesel Engine with Datura Biodiesel

Abstract
The depleting of fossil fuels has simulated the worldwide search for the alternate fuels. As our country is an agricultural based one and large amount of land is available, production of Datura biodiesel will be more advantageous for our farmers. The Datura biodiesel is a perfect replacement to diesel because this is derived from indigenous sources and is renewable. But due to its high viscosity and lower calorific value it cannot be directly used in the diesel engine without major modifications to the engine. Hence in the present work it is planned accordingly to use the various combination of diesel and biodiesel in the ratio of 95% diesel and 5% Datura oil (B5), 90% diesel and 10% Datura oil (B10),85% diesel and 15% Datura oil (B15),80% diesel and 20% Datura oil (B20) and 75% diesel and 25% Datura oil (B25). The combustion of the engine depends on the flow capability of the fuel. With the higher viscosity, Daturaoil fluidity will be less and this can be improved with the blends of biodiesel. Further the investigation is planned to study the effect of the performance and emission characteristics of various blends of Datura biodiesel. The whole investigation is carried out in a constant speed vertical cylinder water cooled DI Diesel Engine. The performance parameters are analyzed and the results are presented.
