校准柴油发动机供油正时,是维修中常要做的一项工作。进行这项工作,一般是利用飞轮与壳和喷油泵凸轮轴与接合器接盘上的刻度标记来进行。如果当您需要校正供油正时而遇到标记刻度看不清或没有时,可采用下述办法校准。关键要把握住三点;一是先找出某一缸活塞压缩上止点位置,二是确定供油提前角度的曲轴转角位置,三是调整相对该缸的供油时刻。我们先讨论如何寻找某一缸活塞压缩上止点位置。对于采用直接喷射式燃烧室的发动机,
Calibration of diesel engine fuel timing, maintenance is often done in a job. To carry out this work, the general use of the flywheel and the shell and fuel injection pump camshaft and adapter plate on the scale mark to carry out. If you need to calibrate the fuel supply timing and meet the mark graduation can not see or not, you can use the following method of calibration. The key to grasp the three points; First, find a cylinder piston compression top dead center position, the second is to determine the angle of the crankshaft fuel supply advance angle position, the third is to adjust the relative timing of the cylinder fuel. We first discuss how to find a cylinder piston compression top dead center position. For engines with direct injection combustors,
