What causes diesel generator oil to deteriorate so quickly?

Generally speaking, the new machine needs to be replaced for the first time after working for about 60 hours, so as to promptly remove metal debris and other impurities generated during the running-in stage of the new machine. After that, the oil needs to be replaced every 200 to 300 hours of operation, but the oil sometimes becomes thinner before changing the oil., impurities increase, and cannot be used continuously. Wan Peng Power Editor shares some reasons with you.

Why does diesel generator oil get faster?

1. Effect of high temperature: The high temperature generated when the engine is working will accelerate the oxidation of the oil and form oxidation products, causing the oil to deteriorate. If the cooling system fails, the engine temperature will be too highand the oil will deteriorate;

2. Impurity pollution: Dust, particles, etc. in the air enter the engine and mix with the engine oil, accelerating the deterioration of the engine oil. Impurities such as metal debris generated by internal wear of the engine can also contaminate the engine oil and degrade its performance;
3. Water mixing: When the cooling system leaks, the coolant enters the engine oil, which will cause the engine oil to emulsify and deteriorate; when the environmental humidity is high, or the engine is working in a humid environment, water vapor enters the engine oil, which will also cause deterioration;
4. Fuel dilution: Fuel injection system failure causes fuel to not fully burn into the crankcase, diluting the oil, reducing the viscosity of the oil, and making it deteriorate;
5. Oil quality problems: Oil of poor quality and unsuitable for the engine is used. Its anti-oxidation and wear properties are poor and easy to deteriorate;
6. Long-term operation: The diesel generator operates continuously for a long time, and the oil continues to be under harsh working conditions such as high temperature and high pressure, accelerating its aging and deterioration.Therefore, we must prevent the oil from deteriorating.
How to prevent engine oil from deteriorating? There are five methods to choose from:
1. Control operating temperature
Ensure that the cooling system is operating normally and regularly check components such as coolant levels, radiators and cooling fans to avoid engine overheating and increased oil oxidation.
Avoid long-term high-load operation, reasonably arrange generator working hours and load to prevent rapid deterioration of engine oil due to high temperatures.
2. Prevent impurities from mixing in
Keep the engine and surrounding environment clean and clean up dust and debris in a timely manner. When adding engine oil, use a clean funnel and container to prevent impurities from entering.Regularly replace the air filter and oil filter to ensure that the air and oil entering the engine are clean and reduce contamination of the oil by impurities.
3. prevent moisture from entering
Although there is a specified oil change period, due to the different degrees of wear and different oil quality of diesel engines, different regions, climates and working conditions have an impact on the oil change cycle. Changing oil too early will cause waste, and replacing it too late will cause other diesel engine accidents. Check the tightness of the cooling system to prevent coolant leakage into the oil. If the coolant level is found to have dropped abnormally, promptly investigate and repair it.Avoid parking the generator for a long time in a humid environment. If it is inevitable, take moisture-proof measures, such as using desiccant, etc.
4. Correct selection and storage of oil
Select the appropriate specification and quality level of oil according to the requirements of the generator's operating instructions to ensure that it has good oxidation resistance, wear resistance and other properties.Oil should be stored in a cool, dry and well-ventilated place, avoid direct sunlight and high temperature environments, and prevent mixing with moisture and impurities.
5. regularly inspected and maintained
Regularly check the level, color, smell and viscosity of the oil, and replace it in time if any abnormalities are found.
Regularly change the oil and oil filter according to the specified time or operating hours to ensure that the oil always maintains good performance.
