摘要
介绍了燃油密度随压力和温度的变化关系的经验公式 ,并根据各参数间的严格关系推出了压缩率和音速的经验公式 ,还介绍了粘度的经验公式。经与试验结果对比 。
In this paper, the experiential formula of fuel density variation with pressure and temperature is put forward and the experiential formulas of fuel compression ratio and sonic velocity are also derived in light of the strict relationships of fuel parameters, and besides, the viscosity experiential formula is recommended. The experiential formulas offered in this paper possess high precision according to the experimental results.
