The engine oil has a service life and will not work when certain conditions are met. In order to ensure the normal working conditions of the engine oil, such as low temperature viscosity, anti-corrosion and anti-corrosion properties, proper oil dispersion, etc. This article will summarize the causes of engine oil deterioration.
1. Abrasive contamination
During operation, dust, sand or other impurities on the construction site may enter the engine oil and cause rapid wear with the circulation of engine oil.
2. Pollution of combustion by-products
Combustion will produce a large amount of water vapor. When the temperature is low and the engine is started or preheated, the water vapor will condense on the cylinder wall and then enter the crankcase to form oil sludge with the incompletely burned fuel. In addition, acid substances will also be produced during combustion, which may corrode parts or rust parts, and the generated sediment will block the filter.
3. Caused by improper cleaning method
When cleaning the crankcase, if the engine oil filter or radiator is not cleaned thoroughly or the sealing gasket of the oil filter is missing, the newly added oil may turn black and dirty quickly. In addition, if the filter element of the filter is blocked or damaged and not cleaned or replaced in time, the engine oil will deteriorate due to the weakening of the filtering capacity of the filter.
4. Improper selection of engine oil
When changing the engine oil, attention should be paid to the selection of engine oil. Products that meet the quality requirements and have the same grade must be added according to the requirements of the operation manual.
