The car air filter is installed in front of the carburetor or intake pipe to filter the air that enters the engine. The engine needs to suck in a large amount of air during the working process. The air contains a lot of dust particles. If it is not filtered by the air filter, 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. Summary The role of the car air filter is to filter out the dust and debris particles in the air, ensuring that sufficient clean and dry air enters the cylinder.
In daily maintenance, we need to regularly check and maintain the car air filter. After a period of use, the car air filter will become dirty and needs to be cleaned or replaced in time. How to judge that the air filter is dirty is also a problem. The method for determining whether the air filter element is dirty is as follows:
1. You can look at the operating status of the engine. If the air filter element is dirty, the air intake will be insufficient and the fuel will not burn sufficiently, which will cause the engine to work unstable. The exhaust gas is thick and black;
2. You can check the surface color of the air filter, ifAfter the dust on the surface of the air filter element is cleaned, the filter paper is still gray-black, indicating that the filter paper can no longer be used and should be replaced immediately.
The replacement cycle of the air filter element depends on the use of the car and the surrounding environment. Under normal driving conditions, the air filter element needs to be replaced every 15,000 kilometers of the car. If you often drive in a poor environment, the replacement cycle should be appropriately shortened, and no more than 10,000 kilometers should be replaced once. The habit of regular inspection and timely maintenance should be developed.
