Description
Technical field
The present invention relates to auto parts field, specially a kind of environment-friendly type double-decker automobile exhaust pipe.
Background technique
Recently as going deep into for China's reform and opening-up, national economy is continued to develop, and sale of automobile amount is increasing sharply,
Automobile becomes our indispensable vehicles, and by the end of the year 2014, China's automobile quantity is up to 1.4 hundred million, it is predicted that the year two thousand twenty,
China's automobile quantity is up to 2.5 hundred million, and incident vehicle exhaust also has become the primary pollution source of atmosphere, China city
In city's atmosphere pollution, motor vehicle exhaust emission proportion more than 70%, so, reinforce motor vehicle emission administer it is very urgent.China
Automobile consumption of petroleum amount accounts for about 1/3 or more of national oil consumption, and with the rising of car ownership, China's auto-pollution
Object total emission volumn also increases increasingly, and the joint investigation from the United Nations's science, education, culture and health tissue and environmental organization is shown: modern city
In pollution, auto-pollution accounts for 34%.Its tail gas pollution at least cannot exclude in 20 years, and this will bring not for 20 years to urbanite
Appreciable disaster will cause huge damage to the breathing of people, vision, the sense of hearing, spirit.Therefore, in automobile industry development and ring
Between the protection of border, need to seek new balance, China's oil consumes 5.43 hundred million tons within 2015, and wherein the part of automobile consumption accounts for three
/ mono-, and be continuously increased also with China's car ownership, consumption of petroleum amount is also being continuously increased.Therefore, thereupon
Be more acute environmental pollution, this largely affects people's lives and physical and mental health.It is a large amount of due to discharging
Vehicle exhaust, easily cause photochemical pollution, domestic some big cities are particularly evident, such as Beijing, Nanjing, Shanghai
Deng NOx is also the main source of urban air pollution, and the pollution of small and medium cities NOx also becomes increasingly conspicuous.
Traffic system consumes the energy in the whole world about 1/3 at present, is most important existing using oil product as the automobile of fuel
The problem of can not avoiding also is brought while it brings convenient and quick for transport facility.According to last generation
Record the seventies and eighties U.S., investigation of the Japan to urban air pollution source, 90% or more carbon monoxide in urban air, 60% with
On the nitrogen oxides of hydrocarbon and 30% or more both be from the discharge of vehicle exhaust, these dirty gases make the mankind's
Living environment is by great threat.Auto-pollution has become worldwide public hazards, increased for greenhouse gas concentration " contribution "
It can not be ignored.With the increase of countries in the world car ownership, automobile has become the primary pollution source of urban air quality deterioration,
The pollutants such as its CO, NOx, HC, SO2, Pb for discharging not only are detrimental to health, and still cause the master of acid rain and photochemical fog
Ingredient is wanted, automobile exhaust pollution is widely watched attentively by the whole world.Ended for the end of the year 2006, China's motor vehicles for civilian use ownership has been approached
37000000, and still remain the trend of rapid growth.Though compared with developed countries, total amount is few, due to mainly concentrating
In big city, and vehicle condition is poor, and fuel oil quality is low, and the blowdown flow rate of bicycle is often higher by several times of external similar vehicle, vehicle exhaust
Huge threat is caused to China's urban air-quality.Therefore, the new technology of the emission control of vehicle exhaust is studied, is reduced harmful
The discharge amount of gas ensures environment for human survival, is of great significance to the quality for improving urban air.
