供油提前角

• The construction of conical nozzle is used by pump ' s delivery - valve , making use of the dynamic characteristics of conventional . short pipe to enhance injection pressure . there are three parameters of fuel injection system : response pressure , injection - advanced angle , injection valve bulge high degree , the best match was found by adjusting them
  在油泵出油阀端，采取渐缩管结构措施，利用管路动态效应提高喷油压力；对于喷油系统参数：喷油压力、静态供油提前角和油嘴凸出高度，三个参数进行调整试验，找到它们的最佳匹配。
