| Abstract: | Straight vegetable oils provide cleaner burning and renewable alternatives to diesel fuel, but their inherently high viscosity compared to diesel is undesirable for diesel engines. Lowering the viscosity can be achieved by either increasing the temperature of the oil or by blending it with diesel fuel, or both. In this work the rheological properties of diesel fuel and vegetable oil mixtures at different compositions are measured as a function of temperature to determine a viscosity-temperature-composition relationship for use in design and optimisation of heating and fuel injection systems. The vegetable oils tested are canola, olive, peanut, and soybean oils which are commercially available. All samples tested between 20 C and 80 C exhibit time-independent Newtonian behaviour. A mixture viscosity model has been developed to predict the viscosity of the vegetable oil- diesel blends as functions of temperature and composition |
