The function of automobile air filter, what happens when it is dirty?

The main function of automobile air filter is to filter the air entering the automobile engine and ensure that the air entering is relatively pure. If the air filter element is too dirty, it needs to be replaced. If the air filter is too dirty and a lot of dust is attached, it will hinder the air from passing through and reduce the air intake of the engine, thus further reducing the engine power and increasing fuel consumption.

1. The air filtered by the air filter element is mixed with fuel to form a combustible mixture, which is burned in the cylinder. If there is no air filter element in the air intake system, the air entering the cylinder may carry fine sand, particles or other non-combustible foreign bodies, which may wear or damage the cylinder wall, piston, movable cold ring and valve. In order to ensure the reliable operation of the engine and prolong its service life, air filters are essential in automobiles.

2. The material of air filter element is generally paper or fiber cloth, cotton yarn, non-woven fabric, felt, etc. , especially paper materials. Its design allows air to pass through, but foreign objects and particles will be prevented from passing through. After each period of use, there will be a lot of dust and foreign objects on the air filter. When doing routine maintenance for the car, the maintenance master will usually use a high-pressure air gun to clean it for you. The air filter element has a certain service life, which is generally one year or tens of thousands of kilometers. After reaching the service life, it is recommended to replace it to ensure the purity of the intake air.
