Method for controlling total injection amount in multiple injections

A method for controlling the total injection amount per duty cycle in multiple injections of a fuel injector of an internal combustion engine is described. In the method, an injection quantity difference is determined step by step from a single injection pulse to a single injection pulse and is transmitted to the next single injection pulse. The remaining injection quantity difference in the last but one single injection pulse is passed to the last single injection pulse to obtain a total injection quantity with an improved allowable error. 描述一种用于在内燃机的燃料喷射器的多次喷射中控制每个工作循环的总喷射量的方法。在该方法中，逐级地从单次喷射脉冲到单次喷射脉冲求取喷射量差，并且传递到下一单次喷射脉冲上。在倒数第二单次喷射脉冲中剩余的喷射量差被传递到最后的单次喷射脉冲上，以获得具有改善的允许误差的总喷射量。
