The maintenance engine filter helps to prolong the service life of the engine

The air filter dirty will hinder the fresh air into the cylinder, thus affecting the air and the gas mixing ratio. According to the test, complete combustion of 1G gasoline, need 15g about air. If the air entering the cylinder gas mixture is insufficient, cannot complete combustion, waste gas, lack of engine power, and the removal of HC and CO components in the exhaust gas pollution of the environment more.

Inevitably contain dust and other impurities in the air, its content with different local soil, climate and road conditions and different. According to the test, when the car in the dusty dirt road, air filter air filter every about 1 cubic meters of 0.4 ~ 1.8g. These dusts, its chemical composition, the majority is silica. When they enter the friction surface, it will penetrate through the oil film, increased wear of engine cylinders, shorten the service life of the engine.

Modern cars use an air filter paper, paper filter filtration efficiency is high, the rate is only 0.1% to 0.3% of dust. The use of paper air filter can reduce the wear of cylinder and piston, prolonging the service life of the engine. Use and maintenance should pay attention to the following points:

(1)Grasp the characteristics and methods of cleaning the paper filter
This filter uses microporous filter, after surface treatment. When the engine is working, air dust filter through microporous, ensure clean air into the cylinder. In use, the filter will stick around there is a layer of dust, clean, cannot use water or oil, to prevent the oil dip filter. There are two kinds of cleaning methods: ①Pat method, to filter out from the shell, gently pat face makes paper filter dust off, not on the outer surface of filter elements, to prevent damage to the filter. ②purging, which uses compressed air from the interior of the filter element out blowing, blowing the dust net. To prevent damage to the filter, compressed air pressure is not more than 0.2 ~ 0.3MPa.

(2)Regular cleaning and replacement of filters
Should be in accordance with the provisions of vehicle maintenance in use, often clean the air filter element, so as to avoid too much dust filter on adhesion and increased the intake resistance, reduce engine power, increased fuel consumption. Such as filter damaged should be replaced promptly.

(3)The correct installation, prevent the air is filtered into the cylinder
In the inspection and maintenance of air filter, gasket on the filter element must be installed. If the seal has been aging deformation or fracture, should be replaced with a new one.

(4)The replacement of the new filter, filter selection should be original factory supply, do not use inferior filter
Generally from the packaging and appearance quality and poor recognition element, can also be installed after the inspection, such as installing a new filter, auto emissions exceed the standard discharge of CO, is not installed filter of CO compliance, the filter permeability difference, is the core of the unqualified. Buying filter, remind everybody, to the formal auto parts stores to buy, otherwise easy to buy fakes.
