测量分析柴油机加速工况瞬时转速、油管嘴端压力、针阀升程等参数每循环变化，根据实测油管压力及瞬时转速，进行喷油过程的模拟计算，分析了供油提前角、喷油提前角、喷油持续角、喷油规律、循环喷油量等参数在加速工况每循环的变化，并与试验结果对比表明有较好的吻合性。 Measurement and analysis of the instantaneous speed of diesel engine acceleration conditions, the nozzle end pressure, needle valve lift and other parameters change every cycle, according to the measured tubing pressure and instantaneous speed, the injection process simulation, analysis of the fuel supply advance angle, injection advance Angle, the continuous angle of injection, injection law, the amount of circulating fuel injection and other parameters in the acceleration of each cycle changes, and compared with the test results show a good agreement.
