在文献〔1〕中,对于高压段剩余压力对喷油过程的影响(对以后的循环来说是最初的循环)作了理论分析。为了证实理论分析结论以及对剩余压力对中速柴油机喷油过程影响作定量鉴定,对内燃机车用370(1625/27)型强化发动机的燃油装置进行了计算研究。曲轴转速为1000r/min,标定功率为2940kW。根据教授研究的喷油过程流体动力计算方法,并考虑了文献〔3〕中所提出的修正,进行了计算研究。计算中,燃油设备的主
In [1], the theoretical analysis of the effect of the residual pressure in the HP section on the fuel injection process (the first cycle for the later cycle) is made. In order to confirm the conclusion of theoretical analysis and quantify the effect of residual pressure on the injection process of medium speed diesel engine, the fuel unit of 370 (1625/27) type reinforced engine for diesel locomotive was calculated and studied. Crankshaft speed of 1000r / min, calibration power of 2940kW. Based on the calculation method of fluid dynamics of fuel injection process researched by Professor, and taking into account the corrections proposed in [3], the calculation and study are carried out. Calculation, the main fuel equipment
