【摘要】 本文根据实测的柴油中音速和借助某些近似结构计算流量系数的方法,对喷油过程进行变音速、变密度和变流量系数的计算。计算结果与试验结果的对比,确认了作者的FISC程序的正确性,该程序同时具有预报二次喷射和空泡现象的功能。更多还原

【Abstract】 According to the measured mid-sonic speed of the diesel oil and by using some methods for calculating discharge coefficient with approximate construction, this Paper calculates the fuel injection process in which sonic speed, density and flow coefficient vary respectively. The comparison between the calculation result and experiment result confirms the correctness of FISC (fuel injection system calculation)program made by the authors, which also serve the function of predicting second injection and cavitation.更多还原
