常見例句雙語例句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(yōu)化并對柴油機供油量、供油提前角和針閥開啟壓力進行優(yōu)化匹配，然后對ZS195柴油機燃用二元燃料進行試驗研究。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(jié)論是：上止點前150℃A以后的預(yù)噴提前角，其預(yù)噴與主噴柴油都以擴散燃燒為主； 返回 injection advance angle
