How does the oil filter work?
I believe that all owners know that cars (in addition to trams) need to use oil filters, but do you know how oil filters work?
In fact, the working principle of the oil filter is not complicated, during the operation of the engine, with the operation of the oil pump, the oil with impurities continuously enters the oil filter from the oil intake port on the bottom assembly of the oil filter, and then goes through the check valve to the outside of the filter paper for filtration.
Under the action of pressure, the oil continues to pass through the filter paper into the center tube, and the impurities in the oil remain on the filter paper.
The oil entering the center tube enters the engine lubrication system from the oil outlet in the middle of the oil filter bottom plate.
There are two key components: the bypass valve and the check valve.
Under normal circumstances, the bypass valve is closed, but in special cases the bypass valve will open to ensure the normal supply of oil:
1, when the filter exceeds the replacement cycle, the filter element is seriously blocked.
2, the oil is very viscous (cold start, low external temperature).
Although the oil flowing through this time is unfiltered, it is much less damaging than the damage caused by the engine without oil lubrication.
When the vehicle stops operating, the oil inlet check valve is closed to ensure that the oil in the oil filter and subsequent lubrication system is not emptied, to ensure that the required oil pressure is established as soon as possible when the engine starts again to avoid dry friction.
See here, I believe you have a general understanding of the working principle of the oil filter.
Finally, remind you that the life period of the oil filter must be replaced in time, and when buying the oil filter, please choose the products of the regular channel, otherwise the damage to the engine is not worth the loss.
