供油定时供油终点为上止点前20°。供油始点可变,从低转速时的29°到高转速及高负荷时的47°。图1表示喷射及供油的规律,其基点是在1500转/分时有2500马力的功率,按螺旋桨特性工作。图中并表示有理论的供油始点及其延迟,喷射的始点及其终点等。高压泵的供油凸轮型线及运动规律根据高压油泵工厂(Bosch)的资料,凸轮型号ERR—SK3060A,基圆直径60毫米,滚
The timing of oil supply timing is 20 ° before top dead center. The starting point for oil supply is variable from low speed 29 ° to high speed and high load 47 °. Figure 1 shows the law of injection and fuel supply, the basic point is 1500 hp / 2500 horsepower, according to the propeller characteristics of work. The figure also shows that there is a theoretical starting point for oil supply and its delay, the starting point of injection and its end. High-pressure pump fuel supply cam profile and movement According to the high-pressure pump factory (Bosch) information, the cam model ERR-SK3060A, base diameter 60 mm, roll
