Abstract: Alternative fuels for internal combustion engine are area of research for past few decades because of limited quantity of fossil fuel used today. Biodiesel fuels are one of the candidates of the alternative fuel for compression ignition engine due to many advantages. In this research performance of single cylinder, 4-stroke, water cooled, variable compression ratio diesel engine running using jatropha biodiesel blends (B10 to B50 with increment of 10) is discussed. Nonedible biodiesel blend is chosen to avoid food security related problem in case of edible oil based biodiesel. Engine was run at default set compression ratio of 17.5 and injection pressure of 180 bar. Performance was measured at three different loading condition for each blends used in investigation. It was found that at lower blends performance is similar to that of diesel fuel. Highest thermal efficiency was found for B20 v/v blend which was 26.43% while other blend B30 shown similar thermal efficiency compare to diesel but was lower than B20. Emission of engine running with biodiesel was almost similar to that of diesel and there was no significant difference observed
