大多数单缸柴油机,整机的结构基本相同。即由曲柄连杆机构,配气机构、燃料供给、润滑、冷却及其他装置组成。由诸多部分组成的单缸柴油机,一旦发生故障,从何入手去分析、排除其故障,是否有规律可循?这是单缸柴油机用户极其关心的问题。解决这个问题,其实是有规律可循的,掌握这个规律,就可以大大减少分析、排除故障的盲目性,使排除故障有序地进行。 第一、要分析、检查柴油机的压缩性能,从而排除故障。其步骤如下:在未拆开柴油机之前,不减压的情况下,通过旋转飞轮(顺时针转动),观察飞轮是否有反弹(反转)的现象。如果有反弹,而且反弹很大,就可以断定柴油机的压缩性能很好;反之,则压缩性能就差。压缩性能差的话,就要检查柴油机
Most single-cylinder diesel engine, the structure of the machine is basically the same. That is composed of crank and rod mechanism, valve mechanism, fuel supply, lubrication, cooling and other devices. By many parts of the single-cylinder diesel engine, in the event of failure, where to start to analyze, rule out the failure, whether there is a law? This is a single cylinder diesel engine users are extremely concerned about the problem. To solve this problem, there is actually a rule to follow. By grasping this law, the blindness of analysis and troubleshooting can be greatly reduced, so that the troubleshooting can be conducted in an orderly manner. First, we must analyze and check the compression performance of the diesel engine so as to eliminate the fault. The steps are as follows: Without disassembling the diesel engine, without decompression, by rotating the flywheel (clockwise rotation), to observe whether the flywheel bounce (reverse) phenomenon. If there is a rebound, and rebound great, you can conclude that the compression performance of the diesel engine is good; the other hand, the compression performance is poor. Compression performance is poor, we must check the diesel engine
