Performance and Emission Analysis of Compression Ignition Engine with Methyl Ester of Jatropha and Diesel

Background/Objectives: The alternate fuel is required worldwide to rectify the future demand and to deduce the
emission in the IC engine. The main objective of this work is to analyze the characteristics of Methyl Ester of Jatropha as alternative fuel. Methods/Statistical Analysis: The various fuel blend ratio of MEOJ (Methyl Ester of Jatropha) was used in compression ignition engine with diesel fuel at constant speed. The different blends B20MEOJ, B40MEOJ,B60MEOJ, B80MEOJ and B100MEOJ were used for engine testing purpose. Findings: Performance, combustion and
emission characteristic of the diesel engine was compared with the blends of jatropha for better efficiency and to reduce
the emission. In maximum load, for B20MEOJ blend the efficiency is 27.93% and for diesel is 28.18%. Smoke density for B20 blend of MEOJ at maximum load is 61.9 HSU while that for diesel is 81.2 HSU. The heat release rate is about 57.75 J/ degree with diesel, 53.57 J/degree for B20 blend MEOJ. Application/Improvements: Biodiesel blend has performance
closer to diesel, but emission is reduced in all blends of MEOJ compared to diesel. Thus the work marks for the suitability of biodiesel blends in diesel engine as an alternate fuel.
