What is the Reason for the Blue Smoke of Yuchai Diesel Generator Set

With the development of social life, Yuchai diesel power generation is more and more widely used in various fields. There are always some problems in the use of mechanical equipment. Today, Dingbo Power focuses on the reasons for the blue smoke of Yuchai diesel generator set.

1、 When Yuchai diesel generator unit is suffering from blue smoke fault, the user should check the lubricating oil scale first. If the lubricating oil scale is lower than the standard, it will cause blue smoke of the unit. In addition, if the lubricating oil is too much or too thin, it will also cause smoke of the equipment. Therefore, we must pay attention to replacing or adding lubricating oil in time.

2、 The blockage of the air filter will also lead to blue smoke from Yuchai diesel generator set, because if the air inlet of the air filter is not smooth or the oil level of the oil basin is too high, the air entering the cylinder will be reduced, and the proportion of fuel mixture will change, resulting in incomplete fuel combustion, thus causing blue smoke from the generator.

3、 If Yuchai diesel generator sets continue to emit blue smoke, and with the increase of power, it may be because the oil level of the oil pan is too high, which leads to too much oil of the lubricant, too much oil of the piston pump, too high oil level of the oil basin, and the splashed oil mist particles are sucked into the cylinder together with the air during the suction process, so the exhaust emits blue smoke.

4、 Due to the long-term low load operation of the generator, the gap between the piston and the sleeve cylinder is too large, which makes the lubricating oil in the oil pan easy to escape into the combustion chamber and mix with the fuel mixture in the cylinder.

5、 The gap between piston ring and cylinder of Yuchai diesel generator set increases, which will also lead to blue smoke of generator. In general, we need to ensure that the gap between the piston ring and the cylinder of the generator is controlled within a precise range. However, if the sealing between the piston ring and the cylinder cannot be guaranteed, the oil of the large motor will enter the cylinder through the gap, and blue smoke will be generated after combustion. Sometimes, due to the "counterpart" of the piston ring, the oil of the large motor will leak and burn, And blue smoke.

Through the above analysis, I believe you can see that the most common cause of blue smoke from Yuchai diesel generator set is oil leakage. No matter where the oil leakage is, it will lead to blue smoke from the generator. Therefore, Dingbo Power reminds you that if there is blue smoke in the process of using Yuchai diesel generator set, you must check it in time, In order to avoid serious accidents, oh, affect the service life of the unit.
