To Save the Diesel Fuel and Environment Pollution by using Jatropha Oil

The aim of present study is to analyze the performance and emission characteristics of C.I. engine using a suitable bio diesel as a fuel. The bio diesel selected to conduct this experimental investigation is Jatropha biodiesel. The performance of single cylinder water-cooled diesel engine and methyl-ester of Jatropha oil as the fuel is evaluated for its performance and exhaust emissions. The fuel properties of biodiesel such as kinematic viscosity, calorific value, flash point, carbon residue and specific gravity are discussed. Results indicated that B25 have closer performance to diesel and B100 had lower brake thermal efficiency mainly due to its high viscosity compared to diesel. The brake thermal efficiency for Bio diesel and its blends was found to be slightly higher than that of diesel fuel at tested load conditions and there are no difference between the biodiesel and its blended fuels efficiencies. For Jatropha biodiesel and its blended fuels, the exhaust gas temperature increased with increase in power and amount of biodiesel. However, its diesel blends showed reasonable efficiencies, lower smoke, CO2 and CO. Methyl ester of Jatropha offers fuel conservation as well as reduce pollution. The emission constituents are carbon monoxide (CO), unburnt hydrocarbons (HC), oxides of nitrogen (NOX), carbon dioxide (CO2).
