EXPERIMENTAL INVESTIGATION OF CI ENGINE FUELED WITH DIESEL AND KEROSENE BLEND WITH COTTON SEED OIL

Mechanical Engineering

Bio-fuel is renewable engine fuel that can be used directly in any existing, unmodified diesel engine. Bio-fuels create new markets for agricultural products and stimulate rural development because bio-fuels are generated from crops; they hold enormous potential for farmers. In the near future two-thirds of the people in the developing world will derive their income from agricultural products. In this study, the performance of a direct injection diesel engine has been investigated experimentally using 1st generation bio fuel (cottonseed oil) blends with fossil fuel like kerosene and diesel. The first generation bio-fuel (cottonseed oil) has been produced without transesterification reaction and we have made few blends samples of Cottonseed oil & Kerosene with Diesel fuel from literature review. First Flow analysis for various fuel blend which designed we have designed is carried out in this research work by using CFD software. Fuel Flow for various blends through injector of diesel engine is simulated and it gives the Density, velocity, pressure and volume distribution of fuel in combustion chamber. First analysis is done for pure diesel sample. Pure diesel results will be used to compare the results obtained in simulation of optimum fuel Blend. Optimum blend combinations are interpreted from the results obtained from CFD analysis then these optimum blends are tested on C.I. engine test rig. After that Comparison of flow characterizes of pure diesel with Blend sample will justify the technical feasibility of fuel blend which will conclude that the fuel blend sample can be used in single cylinder diesel engine without modification.
