The role of air filter

1. The air intake of a car is as important as human breathing, and the air filter element is a very important filter element in this link.

2. The filter elements of various cars are different, but the functions are completely the same. The ignition of the engine requires gas, and the gas first enters the intake duct from the outside of the car, then passes through the air filter element, then the air flow sensor passes through the throttle valve, and finally enters the engine for combustion.

3. However, the air filter element is particularly important. Some larger dust particles or paper scraps outside the car need to be filtered by the air filter element. The remaining two links, the air flow sensor, is responsible for sending the air into the next link. The throttle valve is to control the intake air. The amount of air flow is directly controlled by the accelerator pedal. The final mixture of air and gasoline is synthesized and burned in the engine.

4. It seems simple but not so complicated. First of all, let’s not talk about the air intake. Because it’s too complicated, let’s talk about the damaged air filter. What’s the problem? First of all, its filtration quality has declined, and some irregular objects will enter the engine seriously. Can cause cylinder pull. Worn car cylinder pistons.

5. Therefore, the filter element is very important. It is necessary to replace it in time and choose a high-quality filter element. Because the high-quality filter element has high density and high filtration performance, it is easy to use for a long time, and false is just the opposite.

6. The specific replacement standard is hard to say because different environments and different footwork will lead to the service life of the filter element, which is generally 20,000 kilometers or one year. The actual shall prevail.
