| Outline of Final Research Achievements |
Bio diesel fuel (BDF) is pressured up above 2000 atm before fuel injection to diesel engine. It is most important to measure the viscosity of the diesel fuel at high pressure. In the present research, dynamic light scattering (DLS) method is proposed to measure the fuel viscosity. This research enables us to measure the viscosity for the high pressure up to 4000 atm. At first, the viscosities of water, methanol, ethanol and 2-propanol as a fundamental fuel are measured. At next stage, the binary oils of methyl oleate +triolein and toluene + triolein are used as the model biodiesel fuel. The normalized viscosity that is defined as the ratio of the viscosity at high pressure and the viscosity at atmospheric pressure is found to be expressed as a linear function of pressure. The critical pressure for freezing point of fuel is also investigated from measurement of sudden changes of refractive index and viscosity at the high pressure.
