A Review Paper on Thermal Performance and Emission Analysis of Single Cylinder CI Engine with Jatropha Oil, Blends with Pure Diesel

In different researches many different types of alternative fuels are used. Based on literature review, it is concluded that for CI engine, Bio-diesel is the most promising alternative fuel. In this project works prospects increasing Jatropha biodiesel-diesel blend ratio as a working fuel in diesel engine is going to be studied by changing engine loads. Also based on experimentation most favorable blend and engine parameters are to be recommended for obtaining better performance. Jatropha biodiesel presents a very promising scenario of working as alternative fuels to fossil diesel fuel. The properties of Jatropha biodiesel can be compared satisfactorily with the characteristics required for I C Engine fuels specially C I engine. Experiments will be performed for three engine loads, i.e. 2,4, and 6 kg using pure diesel fuel and blends o Jatropha biodiesel-diesel i.e. J20, J40, J60, with constant speed of diesel engine. The parameters which will study in performance are thermal efficiency, specific fuel consumption, brake mean effective pressure and volumetric efficiency. The results of experiments observed with biodiesel blends were compared with that of baseline pure diesel.
