中压共轨蓄压式供油系统喷油延迟的研究
Study on Injection Delay of Middle Pressure Common Rail Injection System
【摘要】 研究了中压共轨蓄压供油系统喷油定时的确定 ;提出了一种喷油定时的计算方法 ;分析了喷油延迟的影响因素 ,并进行试验绘制出喷油延迟MAP图。试验表明喷油延迟时间主要受共轨油压和转速影响
【Abstract】 In order to control the injection timing exactly, a calculating measure is put forward. Influential factor of injection delay was analyzed and a MAP of injection delay was drawing according to the experiment. The result showed that injection delay is mainly influenced by common pressure and rotate speed.
