How often does the car air filter change
10,000 to 15,000 kilometers or replace once a year, harsh environments need to shorten the cycle
The replacement cycle of automobile air filter (air filter) needs to be determined by comprehensive driving distance, use environment and vehicle condition. The following are specific suggestions:
Regular replacement cycle
mileage standard : In most cases, it is recommended to change every 10,000 to 15,000 kilometers, and some models can be extended to 20,000 kilometers.
time standard : If the mileage is not up to standard, it is recommended to replace it at least once a year, especially for urban family cars with low frequency of use.
Environmental factors affect
harsh environment : in haze, sand, catkin or humid areas, it should be shortened to every 5000-6000 kilometers or every 2-3 months to check and replace.
expressway : if long-term high-speed driving and clean environment, can be extended to 30,000 km replacement.
The performance and symptoms suggest
If there is air intake decreased , engine performance weakened or car odor , should immediately check and replace the air filter.
Older vehicles or extreme driving conditions (e.g., off-road, high temperatures) require more frequent replacement.
Other precautions
Manufacturer recommendations may vary from model to model, and reference to the vehicle owner's manual is preferred.
air filters function differently from cabin air filters, which are usually replaced more frequently (e.g., every 10,000 km or half a year).
summary : Regular inspection of the air filter status and flexible adjustment of the cycle according to the actual use environment are key measures to protect the engine and maintain the performance of the vehicle.
Automotive air filter (referred to as air filter) is an important part of the engine intake system, its main role is to filter the air into the engine, protect the engine from dust, impurities and other harmful substances, while improving the performance of the engine and fuel economy. The following is the specific role of air filtration:
Filter impurities from the air
The air filter can effectively filter the dust, sand, pollen and other small particles in the air, prevent these impurities from entering the cylinder, avoid the wear of the piston group, cylinder wall and other components, especially to prevent the occurrence of "cylinder pulling" phenomenon.
Protect engine health
By filtering harmful substances in the air, air filtration can reduce carbon accumulation and wear of the engine and extend the service life of the engine. Unfiltered air will accelerate the wear and tear of the internal parts of the engine, and even cause engine damage in severe cases.
Improved fuel efficiency
Clean air helps fuel burn properly, which improves engine power output and fuel economy. If the air filter is dirty, it will lead to insufficient intake, so that the fuel is not fully burned, which will lead to a decrease in power and an increase in fuel consumption.
Improve the driving environment
The air filter can also filter harmful particles in the air, such as bacteria, viruses, mold, etc., to provide a cleaner and healthier air environment in the car and protect the health of passengers.
Maintain air conditioning system performance
The air filter can prevent dust and impurities from entering the automobile air conditioning system, keep the air conditioning system clean, so as to improve the cooling and heating effect of the air conditioning, and improve the driving comfort.
Sum up
Automotive air filtration plays a vital role in the engine system, not only protecting the engine from damage, but also improving fuel efficiency and driving comfort. Therefore, the owner should regularly check and replace the air filter to ensure that it is always in good working condition.
