If the air filter element is not replaced, the power will be affected, and the air filter element will not be replaced for a long time:
1. Air filter element: The air filter element can block out the dust and road dust entering the engine. These hard particles will cause internal wear of the engine, cause scratches on the cylinder surface, adsorb on the surface of closely fitting parts, and cause surface wear of exposed and lubricated parts;
2. Air-conditioning filter element: The main component of the air-conditioning filter element is activated carbon, which is a highly effective adsorption material. As early as the "World War I", it was used in gas masks. Now activated carbon is widely used for air purification in cars or indoors;
3. Activated carbon is a kind of porous carbonaceous material, and its developed void structure makes it have a large surface area, so it is easy to fully contact with poisonous and harmful gases in the air. The strong adsorption force field around the activated carbon pores will immediately draw toxic gas molecules into the pores, so activated carbon has a strong adsorption capacity.

If the air filter element is severely dirty, it will cause insufficient intake air and increase the acceleration hysteresis. At the same time, the lack of oxygen will cause insufficient combustion of the mixture, insufficient power, and need more fuel supply, which increases fuel consumption. In severe cases, the exhaust gas discharged is dense smoke with peculiar smell.
The role of car air-conditioning filter:
1. Make the air conditioner grid close to the shell to ensure that the unfiltered air will not enter the interior of the car;
2. The activated carbon and other substances inside can adsorb moisture, soot, ozone, peculiar smell, carbon oxides, SO2, CO2, etc., which can adsorb moisture strongly and lastingly;
3. It can separate solid impurities such as dust, pollen, and abrasive particles in the air;
4. Ensure that the air inside the car is clean and does not breed bacteria, creating a healthy and comfortable riding environment. It can effectively separate solid impurities such as dust, core powder, and abrasive particles in the air, and can effectively intercept pollen, ensuring that drivers and passengers will not have allergic reactions and affect driving safety.
