供油提前角是指柴油开始喷入气缸的时间(以下简称提前角)。提前角的时间是用曲轴旋转的角度来表示的,即活塞压(?)冲程(感到有很大压力时)的活塞上止点之前的某个角度。S195柴油机的提前角为16°～20°。 当提前角大于20°(喷油过早)时,发动机工作时有敲击声,易损坏机件;启动时会右倒转(反本)现象。 当提前角小于16°(喷油过迟)时,发 Fuel advance angle is the time when diesel starts to be injected into the cylinder (hereinafter referred to as advance angle). The timing of the advance angle is expressed in terms of the angle of rotation of the crankshaft, which is the angle before the top dead center of the piston when the piston pressure (?) Stroke (when feeling a great pressure). S195 diesel advance angle of 16 ° ~ 20 °. When the advance angle is greater than 20 ° (premature injection), the engine works percussion sound, easy to damage the parts; start right reversal (anti-this) phenomenon. When the advance angle is less than 16 ° (fuel injection too late), hair
