1, lubricating oil in splash and cycle lubrication, continue with a variety of metal parts and exposed to the air, the metal catalyst, prompting oil gradually aging deterioration.
2, the lubricating oil in the bearing in contact with the entire high-temperature parts, such as the temperature of the cylinder wall portion 190 to 290 ° C, the crankcase oil temperature is an average of 100 ° C, the oil in such a high temperature under the condition due to severe oxidation and deterioration .
3, Combustion exhaust gas, and not completely burning mixture will be through various gap into the crankcase, they will make oil and sludge, acidic substances, and finally cause the lubricant deterioration failure.
4, dust, metal wear debris, the combustion of coke, and so on, will cause the decline in the quality of lubricating oil.
Therefore, the working conditions of the bearing lubricant is extremely demanding, while the oil is indispensable in maintaining the bearing normal work, which put forward higher requirements on the bearing lubricant performance.
