使用柴油发电机时，柴油发电机产生蓝烟是最常见的故障之一。柴油发电机排气中产生蓝烟的根本原因是柴油发电机的机油与燃烧有关。那就是油异常进入燃烧室。柴油机燃烧机油的原因主要有以下几点。
When ge
nerators working, blue smoke produced is one of the most common faults.The root cause of blue smoke in the exhaust of generators is that the engine oil is related to combustion.That is,oil enters the combustion chamber abnormally. The main reasons that engines burn engine oil are as follows.
(1）含油量过高。如果机油加油过多，机油表面过高，也会导致曲轴箱内废气压力增加。结果和呼吸器故障一样，会导致大量机油进入燃烧室，严重冒出蓝烟。曾经有一个外接油箱的柴油发电机，冒烟严重，耗油严重。起初，它被认为是活塞环和气缸套磨损严重，但拆下气缸盖后，活塞环和气缸套是正常的。经过逐步拆卸和分析，最终发现柴油发电机油箱内的油回油泵进油口被堵塞，大量机油无法返回外部油箱，而且都存在柴油发电机内部，导致柴油发电机严重冒烟。 The oil content is too high. If the engine oil is refueled too much, the surface of the engine oil is too high, which will also cause the exhaust gas pressure in the crankcase to increase. The result is the same as the failure of a respirator, which will cause a large amount of oil to enter the combustion chamber and severely emit blue smoke. There used to be a generator with an external fuel tank, which caused serious smoke and fuel consumption. At first, it was considered that the piston ring and cylinder liner were severely worn, but after removing the cylinder head, the piston ring and cylinder liner were normal.After gradual disassembly and analysis, it was finally found that the oil return pump inlet in the generator tank was blocked, and a large amount of oil could not be returned to the external tank, and it was all inside the generator, causing serious smoke from the diesel generator.
2、气缸套和活塞环磨损严重。由于某些原因(包括磨合不良、空气滤芯质量差、长期低速低温运行、机油质量不合格等)。)，导致柴油发电机活塞环和气缸套早期磨损或异常磨损，使活塞环和气缸套的密封状况恶化。这样一方面，机油直接进入燃烧室燃烧；另一方面，由于气缸套和活塞环密封不严，燃烧气体进入曲轴箱，增加排气压力，迫使机油通过呼吸器进入通气管。如果柴油发电机安装了封闭式呼吸器，大量的机油会进入进气管，通过吸入气缸燃烧，使用柴油发电机时会严重冒出蓝烟；如果在柴油发电机上安装了开式曲轴箱呼吸器，排气口会冒出机油。
Cylinder liners and piston rings are severely worn. Due to some reasons including poor running-in, poor air filter quality, long-term low-speed and low-temperature operation, unqualified oil quality, etc. leading to early or abnormal wear of the piston ring and cylinder liner of the generator, and worsening the sealing condition of the piston ring and cylinder liner.In this way, on the one hand, the oil directly enters the combustion chamber for combustion, on the other hand, because the cylinder liner and piston ring are not tightly sealed, the combustion gas enters the crankcase, increasing the exhaust pressure, and forcing the oil into the breather pipe through the respirator. If the generator is equipped with a closed respirator, a large amount of oil will enter the intake pipe and burn through the cylinder. When the diesel generator is working, blue smoke will be severely emitted.If an open crankcase respirator is installed on the generator, engine oil will come out of the exhaust port.
