Cars must be maintained regularly. During maintenance, the oil, oil filter, air filter and fuel filter need to be replaced, which is referred to as "automobile three filters".
As we all know, any oil has a shelf life, and the quality of the expired oil will decrease, and the protection effect on the engine will be reduced.
But we didn't find that the car filter has a shelf life, so why should it be replaced synchronously? What if it is not replaced for a long time? Let's analyze this problem below.
The auto oil filter is called the "kidney of the engine", its main function is to filter the oil impurities and provide clean oil to the engine.
Since the engine will produce a large amount of carbon deposits, colloids, sludge, metal wear debris, etc. during operation, various impurities are mixed in the oil.
If it is not filtered out, it will increase the wear of the engine. Using a car oil filter will leave these impurities on the filter paper of the oil filter, and the engine can get clean oil.
The bypass valve in the oil filter will open when the oil filter is clogged, preventing the engine from being lubricated by the oil. If the oil filter is not changed for a long time, there are too many impurities adsorbed on the filter paper, and the oil cannot pass through. The bypass valve will be opened, and the oil will be directly supplied to the engine without filtering.
Therefore, the oil filter is generally replaced at the same time when the oil is changed. When choosing an auto oil filter, we must choose original parts or brand parts with guaranteed quality.
Many auxiliary parts and counterfeit oil filters generally have insufficient dirt holding capacity, and the filter paper is blocked in a very short time, and then the bypass valve is opened, and the oil has not been filtered since then. If the opening pressure of the bypass valve is high, it will cause poor engine lubrication.
Also, if you use a long-cycle oil, to avoid the oil filter failing earlier than the oil, be sure to use a long-life oil filter. Choose Filton Filter oil filter manufacturer with wide custom selections.
The air filter is called "the mask of the engine", and its function is to filter out the sand, impurities, etc. in the air, and provide clean air to the engine.
If the unfiltered air enters the engine directly, the hard particles such as sand and impurities in the air will enter between the piston and the cylinder wall, aggravating the wear of the cylinder and shortening the service life of the engine.
The filtration of the air filter in car is done by means of microporous filter paper. These micropores can pass air, but impurities cannot pass through.
After a long time of use, these micropores will absorb a lot of impurities, resulting in a significant decrease in the ability of the micropores to pass through, and the amount of air entering the engine will decrease.
If it is not replaced for a long time, the impurities will enter the engine through the pores of the filter paper under the strong vacuum suction of the engine, and at the same time, the pores of the filter paper of the air filter in the car will become larger, and the filtering effect will become worse, which will lead to increased engine wear.
The replacement cycle of the air filter should be determined on a case-by-case basis. If the air in the area is good and the dust content is low, you can replace it every 10,000 or 20,000 kilometers.
When replacing, you should choose a high-quality filter element with guaranteed quality. Inferior filter paper generally has a larger pore diameter and poor filtration effect, so it is not recommended to use it.
