柴油机喷油过程模拟计算中的几个经验公式研究
Study on Several Experiential Formulas Used in Simulated Calculation of Fuel Injection Process in Diesel Engines
【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 ,推出的经验公式具有较高的精度
【Abstract】 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.
