In order to investigate the phase changing phenomena of Diesel fuel, the critical locus curve of nitrogen-tridecane mixing system was estimated. The result shows that the critical pressure of the mixture indicate a strongly non-linear curve and its peak value is more than 10 times larger than the in-cylinder pressure at the end of compression stroke. Furthermore, we investigated the effect of atmospheric condition in an engine cylinder on the gas-liquid phase-changing process of a fuel-air mixture. The phase change condition from liquid to gas of the mixture was determined with comparing the adiabatic mixing temperature to the dew point temperature obtained from vapor-liquid equilibrium calculation.
