The normal operation of the air filter can avoid premature wear of the engine (abnormal) and maintain the best working condition. Car air filter is equivalent to a human nose is air entering the engine to go through the first hurdle, it is filtered air in sand and some suspended particles, so as to make it into the air to the engine are relatively pure, so as to make engine work normal.
The atmosphere contains 3 different kinds of basic particle pollutants, namely, dust, debris and carbon particles. On the open highway, the dust content is lower than that of the rural area and the construction area. In the area where the dust concentration is large, such as the construction site and the wind blown sand area, the frequency of the inspection and replacement of the air filter must be higher. In the highway and traffic congestion area, because the car emissions focus, so the content of carbon particles in the air was significantly higher. The filter checks should carefully check their folds in the depths. Can often blow the filter core with high pressure. Sometimes, the filter outside looks clean, but its interior has been very dirty, and this time must be replaced immediately.
The air cleaner for preventive maintenance is not exaggeration. Before the air is mixed with the fuel, the air cleaner's function is to filter out dust, carbon, water vapor and other impurities in the air, and to ensure the clean air into the cylinder. Theoretically, when the fuel per unit volume is burned, about 10 thousand unit volume of clean air is required. Typically, the manufacturer recommends that the replacement cycle for the normal maintenance of the air filter is from 1 to km, and a regular check is performed on each km, and the recommended replacement cycle for the maintenance of the air filter is km.
