The air filter can bring a cleaner interior environment to the car. It belongs to automotive supplies and consists of a filter element and a shell. Its main requirements are high filtration efficiency, small flow resistance, and long-term continuous use without maintenance.

The role of the air filter: When the engine is running, a large amount of air is drawn in. If the air is not filtered, the suspended impurities in the air will be brought into the cylinder, affecting the friction between the piston and the cylinder, which may cause damage to the air. There is a serious phenomenon of pulling the cylinder. The air filter is mainly responsible for removing particulate impurities from the air.

The air filter acts as a protector for the engine. By purifying and filtering the dust and sand in the air, the engine can be prevented from being disturbed by external impurities and affecting its normal operation. A well-maintained engine has a long lifespan, and a big part of that is in the protection of the filters.

The dangers of not replacing the air filter in time

If a dirty air filter is used during the driving of the car, it will lead to insufficient intake air of the engine and incomplete combustion of fuel, resulting in unstable engine operation, decreased power and increased fuel consumption. Therefore, the car must keep the air filter clean. Therefore, when you find that the car is weak, the engine sound is dull, and the fuel consumption is high, you should replace the air filter in time.

Air filter replacement cycle: Under normal circumstances, the air filter replacement cycle is every 15,000 kilometers. Vehicles whose air filters often work in harsh environments should be replaced within 10,000 kilometers.

There is no absolute standard for changing the air filter. If you are referring to cars, there is no conclusion to this. You only need to pay more attention to the air filter in the usual inspection and maintenance process to see if the interior is clean and there is no dust accumulation. If the inside is dirty, it must be cleaned or replaced.

How to Identify an Air Filter Replacement

How well is the air filter working, and when it does, does it mean it needs maintenance or replacement?

In actual use, the working state of the engine will be abnormal: for example, the roaring sound is dull, the acceleration is slow; the work is weak; the water temperature is relatively high; and the exhaust gas becomes thick when accelerating, indicating that the air filter is blocked and should be removed in time. Lower the filter element for repair or replacement.

When maintaining the air filter, pay attention to the color change of the inner and outer surfaces of the filter. After removing the dust, if the outer surface of the filter paper is clear and the inner surface is bright, the filter element can continue to be used; if the outer surface of the filter paper has lost its natural color or the inner surface is black, it must be replaced.
