The working principle of the oil filter is to filter impurities and sludge in the oil through the filter element. The oil pump extracts the oil from the oil pan and enters the oil inlet of the filter at a certain pressure. After filtering by the filter element, the clean oil flows into the main oil passage of the engine from the oil outlet to supply the lubricating parts. When the filter block causes the pressure to rise, the bypass valve will automatically open, allowing the oil directly through the bypass pipe into the main oil passage, to ensure the normal lubrication of the engine
The main function of the oil filter is to filter impurities and sludge in the oil to prevent oil deterioration, so as to protect the engine from damage due to wear and tear. Specifically, the oil filter can filter out the impurities such as metal debris, carbon particles and gum gradually produced by the oil generated by the engine during the combustion process, to ensure that the oil supplied to the engine is kept clean, thereby extending the service life of the engine
