大型拖拉机和工程机械,普遍装用了四、六、八、十二缸发动机。多缸发动机在调整气门、检查配气阀以及诊断故障时,需要了解在同一时间各缸都在干什么。但是,逐缸推算多缸发动机在同一时间各缸所处的工作位置,极为麻烦,且易出差错。我们创制了一种推算工具——多缸内燃机在同一时间各缸工作位置表,简称“缸位表”。“缸位表”可制成多种缸数通用的,也可制成一种缸数专用的。图示四、六、十二缸三种缸数通用的“缸位表”。它能准确地指出在同一 Large tractors and construction machinery are generally equipped with four-, six-, eight-, and twelve-cylinder engines. The multi-cylinder engine needs to know what each cylinder is doing at the same time when adjusting the valve, checking the valve, and diagnosing the fault. However, the cylinder-by-cylinder prediction of the working position of the multi-cylinder engine at the same time in each cylinder is extremely troublesome and is prone to errors. We have created a calculation tool—the working position table of each cylinder in the multi-cylinder internal combustion engine at the same time, abbreviated to “the cylinder table”. “Cylinder table ” can be made into a variety of universal cylinder number, can also be made into a cylinder number dedicated. The figure shows the “Cylinder Level Meter” common to the four, six and twelve cylinders. It can accurately point in the same
