Fault Analysis of Oil Blackening in Daewoo Generator Set

May. 16, 2023

Excellent quality and reliable performance are the characteristics of Korean Daewoo power generation equipment, among which the grade and quality of oil play an important role. But recently, Starlight received feedback from customers that the oil of the Daewoo generator set in South Korea had blackened to varying degrees before reaching the replacement period. What is the reason for this?

The fuel of Daewoo generator set in South Korea was not completely burned when it was working, and the wear between the piston, piston ring and cylinder block was too large, and the seal was not tight. If the fuel combustion is not complete, the exhaust gas entering the lubricating oil tank will quickly make the lubricating oil black and thick.


When changing the oil, the lubricating oil tank and oil duct were not cleaned thoroughly. If not cleaned thoroughly, the residue will contaminate the new oil, causing the color of the oil in the Korean Daewoo generator set to turn black, and the lubricating oil level does not meet the usage requirements. High temperature, high-speed, and high load engines should use high-grade lubricating oils with good oxidation stability and additive quality. The use of low-quality oils can quickly deepen and darken the oil color.


If the oil of the Korean Daewoo generator set turns black before the replacement period, you need to pay attention, promptly identify the cause, and take measures to solve it. This is crucial for the normal operation of the Korean Daewoo generator unit. If you encounter any unresolved issues during use, please contact the technical personnel of Jiangsu Lide in a timely manner and do not handle them arbitrarily.
