测量100个循环喷油器各孔喷雾冲击力，计算得到了各孔喷油规律，分析了各孔喷油持续期、平均喷油率及循环波动随喷油泵转速和循环喷油量的变化，以及各孔喷油持续期、平均喷油率与对应循环喷油量的相关性。结果表明：对于柱塞式泵-管-嘴系统，随喷油泵转速的升高，各孔平均喷油率均值逐渐减小，其波动率逐渐减小；随喷油量的增加，平均喷油率均逐渐增加，波动率逐渐减小；随着喷孔轴线与针阀轴线夹角的增加，平均喷油率均值减小；各孔平均喷油率与循环喷油量具有较大相关性。

The injection characteristics for each hole of injector was acquired by measuring 100 cycles of spray moment .The variation of injection duration ,mean fuel injection rate and cycle-to-cycle variation with fuel pump speed and fuel injection quan-tity ,and their correlation with corresponding fuel injection quantity for each hole were analyzed .The results show that the mean fuel injection rate for each hole of plunger-type pump-pipe-nozzle system decreases and increases gradually with the in-crease of fuel pump speed and fuel injection quantity respectively ,and its cycle-to-cycle variation both decrease with the increase of fuel pump speed and fuel injection quantity .In addition ,the mean fuel injection rate decreases with the increase of angle be-tween nozzle orifice axis and needle valve axis .Accordingly ,the mean fuel injection rate for each hole has great correlation with fuel injection quantity .
