In the present study biodiesel is collected from Bindle group and it blended in various proportions with diesel were studied. The torque, brake power and fuel consumption values associated with these fuels were determined under certain operating condition. Maximum brake power for all the blend as well as diesel is obtained in the speed range of 1520 rpm. Maximum Brake power for JB 80% is 1.83 Kw at 1500 rpm & for diesel is 1.82 Kw at 1444 rpm. Increase in power may be due to complete combustion of oxygenated fuel. With increase in speed, specific fuel consumption first decreases and than increases. Specific fuel consumption (sfc) also increases with increase in blend percentage. All the blend gave minimum sfc at 1444 rpm for diesel is 0.49 kg/kwh, JB 20% at 1490 rpm is 0.45 kg/kwh, JB 40% at 1480 rpm is 0.51 kg/kwh,JB60% at 1492 rpm is 0.52 kg/kwh, JB 80% at 1500 rpm is 0.49kg/kwh.. The products of Tran’s esterification were evaluated by comparing physical characteristics of biodiesel oil. The biodesel were then tested in diesel engine to observe their actual performance emission. This paper introduces an elegant method for the above required analysis by establishing a definite relationship between fuel properties and engine performance.
