基于先进的 EFS 瞬时喷油量测量仪，采用位移法分别对电控单体泵不同转速工况进行循环喷油量的精确测量。依据循环喷油量及喷油压力的试验数据，得到了电控单体泵喷油量不一致性变化规律以及不同转速下的主要影响因素。分析结果表明，在最大扭矩工况，各单体泵循环喷油量不一致性最低，而启动工况和最大功率工况的不一致性较高。

The cycle fuel injection quantity is accurately measured for electronic unit pump (EUP) operating at high ,middle and low speeds by using displacement method based on EFS instantaneous mono-injector qualifier .On the basis of the experi-mental data about fuel injection quantity and fuel pressure ,the variation of inconsistency in fuel injection quantity of EUP and the influence factors in different operating conditions are concluded .The results show that the inconsistency is lowest in maximum torque condition ,while on the start and maximum power conditions ,it is higher .
