What will happen if the air filter is not changed for a long time?

The function of air filter element is to filter the dust and particles in the air entering the engine and provide fresh air for the engine. If the air filter element does not play its due filtering role, larger particles in the air will enter the engine for combustion. Over time, it will cause engine failure. Simply put, the air filter element protects the engine.

What are the consequences of not replacing the air filter for a long time? 1, the throttle has serious carbon deposition, and the dirty air filtration will first lead to the dirty throttle position. It is easy to cause engine idling instability. 2. Serious carbon deposition inside the engine. Because the air entering the engine is dusty, it will quickly pollute the oil. However, a large amount of dust contained in the engine oil will adhere to the inner wall of the engine under the action of high temperature, resulting in a large amount of carbon mud inside the engine. 3. Fuel with poor power needs air to do work when the engine is burning. If the air filter is blocked and the ventilation is poor, it will inevitably affect the power of the engine. 4. Accelerate the wear of the engine. The air cleaner element filters the air entering the engine. Engines always need a lot of air. Air and gasoline are mixed and burned in the cylinder, so clean air is needed. If the air enters the engine directly without being filtered by the air filter, the dust, sand and other particles in the air will enter the cylinder, which will accelerate the wear of the cylinder.

Air filter is the first line of defense to protect automobile engine, which has great influence on the service life of automobile in actual use. Owners are advised to check regularly.

It should be noted that you should try not to blow with a high-pressure air gun, because the fiber filter layer in the air filter element will be destroyed by the high-speed airflow of the high-pressure air gun, and the originally small filter screen inside will become as big as a sieve after being blown with the high-pressure air gun. Dust invisible to the naked eye will be sucked in at this time. Although the blown air filter is installed in the car, it does not play any filtering role. Some large dust particles entering the engine will accelerate the engine wear and even cause damage.

Air filter replacement cycle: in general, it is replaced once every 65,438+00,000 kilometers, but there is no absolute standard. For example, driving in expressway or areas with good air environment for a long time, it is no problem to replace it once every 30,000 kilometers; If you use the car in a harsh environment and poor air index for a long time, you must shorten the replacement time.
