In different conditions, the maximum pressure rise rate reduced basically according to the retarding of main injection timing, which was consistent with the injection timing in single injection.
与单次喷射相比，采用预喷射会使最大压力升高率有明显的降低。 在不同工况下最大压力升高率基本上是随着主喷提前角的推迟而减小，这与单次喷射中喷油提前角的影响效果一致。

Die casting, the influence factors of filling liquid alloy shape many, including injection pressure, the main injection speed, the fill time and mould temperature, etc.
压铸时，影响合金液充填成型的因素很多，其中主要有压射压力、压射速度、充填时间和模具温度等。
Small amounts of fuel are introduced into the combustion chamber prior to the main injection event, reducing lag time and promoting more continuous and complete combustion.
少量的燃油被引入燃烧室的主要注射液事件之前，减少滞后时间，促进更多的连续和完整的燃烧。
In order to organize the best regionalized combustion, the interval between main injection and post injection should be as small as possible on the premise that oxygen is enough.
要组织最佳的分区燃烧就是要在保证补充氧气足够多的前提下，找到一个尽可能小的主后喷间隔。
