Performance Analysis of Di-Diesel Engine at Different Injection Pressures using Jatropha Methyl Ester
Pages : 165-170
In the present study the fuel used was Jatropha Methyl Ester (J.M.E). The Jatropha methyl ester was prepared in our laboratory by using transesterification process and the physical and chemical properties were determined by using standard experimental setup. J.M.E viscosity is nearer to petroleum diesel at room temperature and flash and fire points are higher than the diesel and calorific value less than the diesel. This JME was utilized for experimentation. Effect of injection pressure on performance of a single cylinder direct injection, naturally aspirated four stroke AV-1 Kirloskar diesel engine fuelled with Diesel, Diesel-J.M.E Blends and 100% Jatropha methyl ester were tested at different injection pressure 160 bar, 180 bar, 230 bar, 250bar and 300 bar. The rated brake power is 3.75Kw, Engine speed is 1500 rpm. It was concluded that at various blends of diesel-JME at 250 bar gives better performanace when compared to the other injection pressures. At this 250 bar injection pressures the Diesel and Neat JME were tested and results shows Neat JME at 250 bar gives better performance compared to diesel.
