What's the function of the air filter and how to maintain it?
On the one hand, if there is no air filter filtration, the engine will contain a lot of dust particles, inhalation of air, resulting in engine cylinder wear; on the other hand, if in use process, not a long time to maintain, airfilter will be covered with dust in the air, which not only makes the filtering ability but also impede the flow of air, causing the mixture too thick so that the engine is not working properly.
At present, the air filters widely used in cars are paper filters, which are divided into two types: dry and wet. The dry filter, once immersed in oil or water filtration, the resistance will be increased sharply, so clean and avoid contact with water or oil, or must be replaced with new parts.
There are two kinds of air filters: paper and oil bath. In recent years, due to the paper filter has high filtering efficiency, light weight, low cost, convenient maintenance, has been widely used. Paper filter filtration efficiency can reach above 99.5%, the oil bath type the filtering efficiency of the filter in the case of the normal filtration efficiency is 95 - 96%.
And if the air is filtered, suspended in the air dust to be sucked into the cylinder, piston and cylinder will accelerate the wear. Between the larger particles into the piston and the cylinder, the cylinder will cause serious phenomenon, which is particularly serious in dry sandy environment.
The air filter is arranged in front of the carburetor or air inlet pipe to play the role of filtering dust and sand in the air to ensure adequate and clean air in the air cylinder. In a car in the thousands on thousands of parts, the air cleaner is a very inconspicuous part, because it is not directly related to the performance of automotive technology, but in the actual use of the car, but the car air filter (especially engine) the life of great influence
