Automobile exhaust refers to exhaust gas emitted by a motor vehicle or other equipment during operation. In modern civilization, automobiles have become an indispensable means of transportation for humans. However, while the automobile industry is rapidly developing and the automobile yield and keeping quantity are continuously increasing, the automobile also brings air pollution, namely automobile exhaust pollution. In large and medium-sized cities in China, automobile exhaust emission becomes a main air pollution source. There are data showing that the total amount of automobiles in Shanghai city is only 1/12 in Tokyo, Japan, but the total amounts of CO, HC, and NOx in the air, which are mainly emitted from automobiles, are substantially the same. The quantity of automobiles in China will be greatly increased along with the rapid development of economy and the increase of social needs. It follows that there is a pressing need to reduce emissions from automobile exhaust.

The components of solid suspended particles contained in the automobile exhaust are complex, and the solid suspended particles have strong adsorption capacity and can adsorb various metal dusts, strong carcinogens, benzopyrene, pathogenic microorganisms and the like. The solid suspended particles enter the lung of a human body along with respiration and are retained at different parts of a respiratory tract in collision, diffusion, deposition and other modes to cause respiratory diseases. When suspended particles accumulate to a critical concentration, the formation of malignant tumors is stimulated. In addition, the suspended particles can directly contact the skin and eyes, block hair follicles and sweat glands of the skin, cause dermatitis and conjunctivitis, and even cause corneal damage.

At present, the automobile exhaust contains carbon monoxide generated by insufficient combustion, and in the prior art, the phenomenon of incomplete carbon monoxide treatment may occur, and if the carbon monoxide is discharged freely, the atmospheric environment is damaged.
