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.
首先對二甲醚添加低比例的柴油進行優化竝對柴油機供油量、供油提前角和針閥開啓壓力進行優化匹配，然後對ZS195柴油機燃用二元燃料進行試騐研究。
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;
其結論是：上止點前150℃A以後的預噴提前角，其預噴與主噴柴油都以擴散燃燒爲主；
