injection advance angle

基本解释

The injection advance angle is too large.
供油提前角太大。
In this paper, the fraction, the cyclic fuel delivery quantities, the injection advance angle and the nozzle opening pressure were studied and optimized in a ZS195 diesel engine.
首先对二甲醚添加低比例的柴油进行优化并对柴油机供油量、供油提前角和针阀开启压力进行优化匹配，然后对ZS195柴油机燃用二元燃料进行试验研究。
It concludes that pre-injection and main injection is mainly diffusive combustion in pre-injection angle of advance between upper dead point and 150? ℃A;
其结论是：上止点前150℃A以后的预喷提前角，其预喷与主喷柴油都以扩散燃烧为主；
