| 摘 要： | 柴油物理特性是模拟计算高压燃油喷射系统的基础。针对柴油的密度、体弹性模量和运动粘度等进行了试验研究，在其基础上得出了柴油密度、弹性模量和运动粘度随压力和温度变化的经验公式，能较好地把柴油的密度、弹性模量和声速统一起来，与试验的误差小于3%，相关系数大于0.998，能满足高精度燃油喷射系统仿真的精度要求。

| Abstract: | The physical properties of diesel oil are the base of simulating high pressure fuel injection system,where the pressure and temperature fluctuation are significant.The density,bulk modulus,kinematic viscosity and vapor pressure of diesel oil are studied by experiments in this paper,from which the density,bulk modulus and kinematic viscosity variations with the pressure and temperature are abstracted.The errors between the calculation data and tested data are less than 3%,and its correlation coefficients are higher than 0.998.The obtained experimental functions have satisfied the high precision requirement for simulation of the fuel injection system. |

| Keywords: | diesel oil physical characteristic density bulk modulus kinematic viscosity |
