What Is The Role Of Car Air Filter

What is the role of car air filter

The role of the air filter is to filter air, just as the engine filter is used to filter the oil. If there is a large amount of impurities, only the air entering the cylinder will definitely affect the engine start, so it is necessary to replace the air filter regularly.

The replacement cycle of automobile air filter elements is generally about 10000-15000 kilometers. Of course, the actual replacement cycle will be affected by the following two aspects:

Air filter quality:

First of all, the use of high-quality filter elements will definitely have a longer service life. Whether it is quality or filterability, it is definitely better to use brand filters such as Mahler and Mann than other brands.

Gas quality:

In areas with poor air quality and heavy sandstorms, the service life of the air filter will be shortened due to the high filtration pressure of the air filter. This is the same as using the three types of fully synthetic engine oil with poor attenuation resistance, and the engine filter can only be replaced at 5000 kilometers, while the use of GT Magic Red and the four types of PAO engine oil with strong attenuation resistance can replace the oil and the engine filter at 15000 kilometers. The principle is the same. .

If the air filter is dirty enough that it needs to be replaced, continuing to use it will definitely affect the air intake system. If the air intake is not smooth or the introduction of a large amount of impurities will affect the normal start, the engine power output and fuel consumption will increase. Moreover, if the machine filter is not replaced for a long time, it may cause the cylinder to be pulled in areas with poor air quality.
