Performance and Emission Analysis of Bio Fuel in Diesel Engine

Biodiesel, a promising substitute as an alternative fuel has gained significant attention due to the predicted shortness of conventional fuels and environmental concern. The utilization of liquid fuels such as biodiesel produced from Jatropha oil by transesterification process represents one of the most promising options for the use of conventional fossil fuels. The physical properties such as density, flash point, Kinematic viscosity, Cloud point and Pour point were found out for Jatropha oil and Jatropha methyl ester. The same characteristics study was also carried out for the diesel fuel for obtaining the base line data for analysis. The values obtained from the Jatropha methyl ester is closely matched with the values of conventional diesel and can be used in the existing diesel engine without any modification. There are concerns ranging from environmental degradation as a result of tremendous noxious tail pipe emissions CO2, HC to global warming due to emission of green house gases from petrol & diesel driven vehicles. Various blends of Jatropha oil methyl ester was to test in diesel. Engine and engine performance results obtained were compared with data obtained from pure diesel. With biodiesel blends, significant reduction in emissions of CO2 emissions measurement using exhaust gas analyzer. Finally, we are conclude that JB 10 gives better performance and less emission rate than the other blending ratio with compared to diesel for all load conditions.
