The dirty air chamber is adapted to receive outside air which, after entering the dirty air chamber, passes through the filter cartridge and into the clean air chamber 10, the air within the clean air chamber 10 being air which has been freed of impurities and is admitted to the engine.

As shown in fig. 3, the air cleaner further includes a carbon adsorption device 2, and the carbon adsorption device 2 is mounted to the filter housing 1 in the filter chamber. The carbon adsorption device 2 comprises a loading shell 21, granular carbon and a gas permeable material film, wherein the loading shell 21 forms a loading cavity and an adsorption window 210, the loading cavity is exposed at the adsorption window 210, the granular carbon is contained in the loading cavity, and the adsorption window 210 is closed by the gas permeable material film. The particulate carbon is enclosed in a space enclosed by a membrane of gas permeable material through which the gas in the filter chamber passes to enter the loading chamber and come into contact with the particulate carbon, and the loading housing 21.

The carbon adsorption device 2 can adsorb hydrocarbon gas reversely volatilized through an air intake system (such as an air filter), so that the environmental protection performance of the vehicle is improved, and national six regulations of automobile emission are met. Moreover, in the process that the outside air enters the engine through the air filter, the desorption of the particulate carbon can be realized, so that the carbon adsorption device 2 has a long service life and can be recycled.
