通过大量的选优匹配试验,找出了喷油嘴结构参数对发动机性能的影响规律,确定了最佳供油提前角,还指出了高喷射率喷油泵对发动机怠速性能的影响,并提出了评定方法。
Through a large number of optimal matching tests, the influence law of injector structural parameters on engine performance was found, and the optimal fuel supply advance angle was determined. The effect of high injection rate injection pump on engine idle speed performance was also pointed out Assessment method.
