The fake oil filter is damaged, the material of the filter paper is poor, soaked in oil for a long time, and the filter paper itself has poor filtering effect under high temperature and high pressure environment. At the same time, a large amount of paper dust will be generated, causing the oil passage of the engine lubrication system to be blocked or the parts to be worn abnormally. In severe cases, it can lead to oil failure, severe engine damage or scrapping.
Due to the poor toughness of the rubber, the gasket of the sealing part of the counterfeit and inferior oil filter is easy to age and crack at high temperature, and the oil is easy to pop out at the joint surface between the machine filter and the cylinder block. , causing oil leakage, poor engine heat dissipation and other failures. There might even be a blowout.
Normally, all parts in an engine are lubricated by oil to ensure proper operation. However, metal shavings, incoming dust, carbon deposits from high-temperature oxidation, and some water vapor generated during the operation of parts will continue to be mixed into the engine oil. Over time, the service life of the engine oil will be shortened, which may affect the normal operation of the engine in severe cases.
The main function of the oil filter is to filter out most of the impurities in the oil, keep the oil clean and prolong its normal service life. In addition, the oil filter should also have the characteristics of strong filtering capacity, small flow resistance and long service life.
