The Function of Air Filter in Car and Its Maintenance

The air filter in car is installed in front of the carburetor or intake pipe and is used to filter the air entering the engine. The engine needs to inhale a lot of air during the working process, and the air contains a lot of dust particles. If it is not filtered by the air filter in the car, it will cause accelerated wear of the piston group and cylinder. If larger particles enter between the piston and the cylinder, it will cause the cylinder to pull. To sum up, the function of the air filter in car is to filter out the dust particles in the air, so as to ensure that a sufficient amount of clean and dry air enters the cylinder. The filtered air participates in the work of the engine, which can reduce engine wear and prolong its service life.

It divided into dry and wet air filters, the two are basically the same in material, usually non-woven fabric or filter paper, and the replacement cycle mainly depends on the vehicle environment. In addition, there is generally no accurate replacement mileage and time for the air filter in car such as the hyundai i20 air filter. Everything is based on the contamination state of the air filter. When the air filter in car is seriously contaminated, it needs to be replaced in time to prevent air intake. Failure to do so can lead to problems such as increased fuel consumption and reduced power.

If the conical air filter for car is dirty, it will cause insufficient intake air and insufficient fuel combustion, resulting in unstable engine operation. When the accelerator pedal is continuously stepped on, the sound of the engine is dull, the acceleration response is slow, the operation is weak, and the exhaust gas is thick and black.

Under normal driving conditions, the air filter in car needs to be replaced every 15,000 kilometers.
