一、供油提前角对柴油发动机工作的影响每种柴油发动机均有自己的最佳供油角度,即必须保证活塞在压缩行程上止点前的适当时刻柴油机的喷油泵开始供油。这个吋刻相对于曲轴转角而言,叫供油提前角。当供油提前角过大(供油过早)时,发动机会产生敲击,工作粗暴,油耗增加,怠速不稳,启动困难;当供油提前角 First, the fuel supply advance angle on the diesel engine work Each diesel engine has its own best supply angle, which must ensure that the piston compression stroke at the appropriate time before the start of the diesel engine fuel pump. This moment relative to the crank angle, called the fuel advance. When the fuel supply advance angle is too large (fuel supply is too early), the engine will produce percussion, rough work, fuel consumption increases, idle instability, difficult to start; when the fuel supply advance
