How often does the air filter change?

The air filter is the same mask we wear on smoky days. It is mainly used to block dust, sand and other impurities in the air. Although this part is inconspicuous and inexpensive, it plays an extremely important role. Someone has done an experiment before. If you remove the car's air filter and drive as usual, the wear of the cylinder is eight times that of a car equipped with an air filter, the wear of the piston is three times, and the piston ring is nine times.

Times. In other words, without this air filter, the engine will be scrapped for two or three years. In addition, it has other hazards. If so many impurities in the air run-in and burn together with gasoline, it will cause insufficient combustion, residual impurities, and carbon deposits. In this way, the car will have insufficient power and increased fuel consumption, and then enter such a vicious circle, and finally the car will be useless.
Generally speaking, the replacement cycle of the air filter element will be indicated in the manufacturer's maintenance manual. Under normal circumstances, the air filter element is recommended to be replaced once 10,000-15,000 kilometers, because the blockage of the air filter element will affect the air intake of the engine over time. As a result, the air-fuel ratio in the engine changes, which affects the combustion process, causing carbon deposits inside the engine, unstable idle speed, reduced power, and increased fuel consumption.
Cars will encounter various situations in actual use. Therefore, there is no absolute standard for the replacement of the air filter, because it depends on the amount of dust and impurities absorbed by the air filter. It is also an air filter. On a vehicle that has been driving on the highway for a long time, it can be replaced after 30000 kilometers or more; for an off-road vehicle that shuttles between countries, it may be replaced within two months. Of course, these two situations are more extreme. For ordinary urban vehicles, it is more appropriate to replace the air filter every year or every 2 kilometers.
Of course, the time or mileage traveled by the vehicle is only a reference value. The final factor in determining whether the air filter needs to be replaced is whether it does not allow enough air to pass through. The air filter must ensure that impurities in the air are filtered out and allow enough air to enter the engine.
It should be noted here that after working for a period of time, the air filter is actually more efficient than the new air filter. This is because the air filter has adsorbed those impurities, which can help it capture more tiny dust. Eventually, the air filter will affect the operation of the engine because of the accumulation of too much dust. At this time, the fuel economy, power and emissions of the vehicle will gradually deteriorate until you replace the new air filter. A tip: An air filter that looks dirty does not mean that it is no longer working properly, so whether it needs to be replaced depends on the condition of the vehicle.
