The function of air filter is to provide clean air for the automobile engine to do work, and to prevent the inhalation of air with impurity particles in the work and increase the probability of abrasion and damage and greatly reduce the engine power.

 

The first question - how often to replace the air filter -

On the question of when to replace the air filter element, different brands and different types may get different answers. Some people suggest that 10,000 kilometers should be replaced once, and some people suggest that 20,000 kilometers should be replaced once.

In fact, the replacement of air filter element needs to depend on the actual situation, such as in some areas of sand, dust, it is recommended that the owner should check the air filter every time maintenance, and shorten the replacement cycle, if necessary, a guarantee a change. In some cities with relatively clean air, the replacement cycle can be appropriately extended.

In addition to dry air filter, there is a wet air filter is divided into oil immersion type and oil bath type. It is generally used in construction machinery and heavy trucks. It can be used repeatedly, as long as it can be cleaned and maintained, but the filtering effect is not as good as dry type.

 

The second question - air filter dirty blowing on the spectrum -

Many owners in the inspection of the air filter, found that the air filter dirty will be blown with an air gun or "play a bullet" outside, that this approach is reliable?

General air filter element will have a lot of wrinkles, to increase the contact area of air, increase the filtering effect at the same time will not affect the engine intake.

So a lot of fine dust firmly attached to the surface of the filter element, is not blown down, at most can only remove the dust on the surface, in fact, not significant. And the fine dust still sticks to the surface.

Note:

Do not use the air gun to blow hard, it is easy to blow the dust into the air filter element, so that the aperture of the air filter element becomes larger and the filtering effect decreases sharply, at this time, many fine particles of dust can not be filtered clean, easily through the air filter into the engine.

 

Third question - what are the problems of air filter damage -

Accelerated engine wear and carbon accumulation

First of all, the engine will accelerate wear and carbon accumulation, if there is no air filter directly open, dust directly into the cylinder, and oil and gas mixed together to burn, the wear degree of the cylinder is eight times that of the air filter car, piston wear three times, piston ring nine times.

Engine inlet dirty

The inlet of the engine will also be dirty, dust is not only run into the engine, long-term use of damaged air filter, even without, the inlet will be dirty.

How to do the air filter element water?

General air filter water, also indicates that the engine has the possibility of water, this kind of situation is more common in summer wading, when this situation occurs, it is recommended that the owner of the first turn off, so as not to cause the engine water top cylinder!
Normal practice, roll out the vehicle, open the air filter shell, clean up the water (check whether there is water in the cylinder), it is best to find a regular repair shop to do simple cleaning, then it is recommended to replace the air filter of water.

 

conclusion

About the replacement cycle of the air filter element, the owners just remember that "according to the environment replacement, replacement needs to be replaced", if the owner has requirements for the performance of the vehicle, it is also recommended to shorten the replacement cycle.
