在进行柴油发动机技术状况检测时,发现一些使用时间不长的柴油发动机在中油门以上有时排气会冒黑烟,机器动力明显不足,直接影响生产的正常进行。其直接原因有气缸内气体压缩力不足以及供油系统有故障等,但引发故障的具体因素却有多种,可以对柴油发动机运转时的诸多现象进行具体分析判断。1.观察燃烧室是否漏气判断燃烧室是否漏气的常用方法是:将柴油发动机先运转至热机状态下及时停车,再用手柄在不减压情况下摇动曲轴,根据各个气缸的工作顺序,感
Diesel engine technology in the detection of the situation and found that some do not use the long-term diesel engine at the gas mileage at the gas exhaust sometimes black smoke, the machine power is obviously insufficient, a direct impact on the normal production. The direct reason for this is the insufficient gas compression force in the cylinder and the failure of the oil supply system. However, there are many specific factors causing the failure, which can be used to analyze and judge many phenomena during the operation of the diesel engine. 1. Observe whether the leakage of the combustion chamber to determine whether the common sense of the leakage of the combustion chamber is: the diesel engine first run to the engine state and timely parking, and then use the handle to shake the crankshaft without decompression, according to the work order of each cylinder, sense
