柴油机在工作过程中,由于有关配合副的磨损或相对位置的变化,往往会导致供油提前角提前或滞后。供油提前角提前或滞后都对柴油机工作不利,必须进行检查和调整,方法如下。 1.首先将拖拉机停稳,然后将变速杆扳到空档位置,用手摇把摇转曲轴,找出第一缸压缩行程。 2.用一根8#铁丝或4～5毫米粗的直钢丝自气缸体后端与拖拉机变速箱连接的凸缘平面上的小孔中(此孔从拖拉机的前端往后看,位于柴油机右侧)插入到飞轮端面上,慢慢顺转曲轴,用插入凸缘平面上小孔中的铁丝或钢丝探寻飞轮端面上的小孔,使两孔对准并将铁丝插入,停止转动,此时正是第一缸活塞处于
Diesel engine in the course of their work, due to the wear or relative position of the vice relative changes in position, often lead to lead advance or lag behind. Fuel advance ahead or lag all adversely affect the diesel engine must be checked and adjusted as follows. 1. First of all, stop the tractor, and then pull the shift lever to neutral position, crank the crankshaft with the hand crank to find the first cylinder compression stroke. 2. Use an 8 # wire or 4 to 5 mm thick straight steel wire from the hole in the plane of the flange attached to the rear of the tractor gearbox to the rear of the cylinder block (this hole is seen from the front of the tractor in the rear of the diesel engine Side) into the flywheel end face, slowly turn the crankshaft, with a small hole in the flange inserted into the hole in the wire or wire exploration flywheel end face of the hole, so that the two holes aligned and the wire inserted to stop turning, this time It is the first cylinder piston
