Abstract: The role of air filter is very simple, in fact, it is a device to filter out particulate impurities in the air.

The role of air filter is very simple, in fact, it is a device to filter out particulate impurities in the air. Because the engine needs to inhale a large amount of outside air when it is working, the "inhalable particles" in the air are filtered out through the filtering effect of the air filter, and then it enters the cylinder to be mixed and burned with the gasoline; if the air filter does not have the proper filtering effect, then Larger particles in the air will enter the engine and burn, which will cause various malfunctions over time. Today, the editor will take stock of a series of issues that car owners are more concerned about.

Question 1: When does the air filter need to be replaced?

In fact, the replacement of the air filter depends on the actual situation. For example, in some areas, where there is a lot of sand and dust, the editor recommends that the car owner check the air filter every time for maintenance and shorten the replacement cycle; while in some areas, the air filter is relatively dusty. In a clean city, the replacement cycle of the air filter can be appropriately extended.

Question 2: Is it reliable to blow the air filter if it is dirty?

If the air filter is not particularly dirty, with only slight sand and dust, it can be blown with an air gun; but if the air filter is already very dirty and affects subsequent use, then this situation must be replaced. In addition, when blowing with an air gun, you must blow lightly. If it is too strong, it will not be good for the air filter.

Question 3: What should I do if the air filter gets water?

Generally, water in the air filter indicates the possibility of water ingress into the engine. This type of situation is more common when wading in summer. At this time, the editor recommends that the car owner first turn off the engine to prevent the engine from entering the top cylinder. The normal method is: push out the vehicle, open the air filter housing, and clean the water. It is best to find a regular repair shop to do simple cleaning, and then it is recommended to replace the air filter with water.

Question 4: If the air filter is dirty, what will happen if it is not replaced?

Dirty air filter will not only affect the air intake of the engine, but also affect the fuel consumption of the engine and the power of the engine. Over time, the correction of the engine fuel system will have a great impact. The most important thing is that the filtering effect of the air filter will decrease, and some dust may enter the cylinder for combustion.


Editor's reminder: Regarding the replacement cycle of the air filter, the owner only needs to remember "replace according to the environment, and change needs to be replaced".
