Abstract
PURPOSE. The paper presents experimental studies on the determination of the compressibility coefficients of diesel fuel and its mixtures with palm oil, as well as pure palm oil in order to estimate the effect of compression pressures and mixed fuel compositions on sound velocity and compressibility coefficients of the fuels under analysis. METHODS. Having reviewed and analyzed the existing methods, the authors chose the method for measuring sound velocity in the fuel located in the discharge pipe. The sound velocity is determined by the moments of initial pressure rise in the inlet and outlet sections of the pipeline. RESULTS AND THEIR DISCUSSION. When the compression pressure and fuel density, which depends on the volume content of palm oil in the mixture with diesel fuel, grow the sound velocity in the fuel increases, while the true compressibility coefficient decreases. In this case the lower the density, the greater the limit variations of the true compressibility coefficient. Therefore, the proof is given to the data of previous studies where it was found out that the dependence of hydrocarbon fuel compressibility approaches the Hooke’s law as fuel density grows. CONCLUSIONS. The results of the study can be used for the simulation of fuel supply in diesel engines operating on the mixtures of diesel fuel and palm oil.
