Research on physical and chemical properties of biodiesel and F-T diesel blended fuel

Physical and chemical properties including density, sulfur content, kinematic viscosity,flash point, distillation range, solidification point, cold filter active point and power performance of different ratio of biodiesel and F-T diesel blended fuels(the volume contents of biodiesel were 0%,10%,20%,30%,40%,50%,60%,70%,80%,90%,100%,respectively) were measured and analyzed.The results showed that biodiesel and F-T diesel could be blended freely; The physical and chemical properties of blended fuel increased with the increase of the content of biodiesel;The physical and chemical properties of B50F was similar to 0# diesel; In contrast with fueling 0# diesel, the output power and torque of diesel engine decreased by using B0,B50F and B100.
