When engine working, the inhalation of air inlet, in the case of without any filtering, the impurities in the air will follow the engine inlet into the engine cylinders, we are invisible to the naked eye of impurity and dust will increase the wear of engine cylinder, if there is a larger area of particle objects into the cylinder, and may cause "cylinder".
As a defense line against dust and impurities in the engine, air filter element is generally installed in the rear of the engine intake pipe. Its purpose is to prevent dust, impurities and particles in the air from entering the engine.
The engine serves as the small heart of the car, the structure is very precise, so appear especially "delicate". The smallest impurities, whether gasoline, oil or air, get into it and have to be filtered through layers.
The following two misunderstandings about air filter elements must be noted:
1. Don't ask for quality when buying
As a result of a few maintenance personnel did not realize the importance of air filters, only cheap, do not ask for quality, buy at will, so that soon after the installation of abnormal engine. Especially in the current market there are many fake and inferior products, we should shop around more carefully and always adhere to the principle of quality assurance.
2. Maintenance and replacement are not based on reality
In the air filter manual, although mileage or working hours are specified as maintenance or replacement data. But in fact the air filter maintenance and replacement cycle and environmental factors. For cars that often drive in dusty environments, the maintenance or replacement cycle of air filters should be shorter; And in the environment with little dust, air filter maintenance or replacement cycle can be appropriately extended.
