What measures has China taken to control automobile exhaust emissions?

1. Improve the environmental protection "label" of fuel;

2. To improve the standard of exhaust emissions, the "Euro 5" standard will be implemented;

3. Some cities restrict the purchase of cars and reduce the number of cars;

4. Some cities implement limited number travel and odd and even number travel to reduce the amount of cars on the road;

5. Advocate green travel, drive less to work, ride to work, take the bus to work and travel.

6. Strictly eliminate old polluting vehicles;

7. Vigorously carry out technological innovation to reduce pollutant emissions from exhaust gas in both engine and exhaust gas;

8. Strengthen law enforcement, strictly manage fuel motor vehicles, and reward vehicles with serious pollution and exhaust gas reported on the road;

9. Vigorously develop non-polluting vehicles, non-exhaust pollution buses, private cars, and first-class cars that strengthen battery cars.

The main pollutants of automobile exhaust are: carbon monoxide (CO), nitrogen oxides (NOx), hydrocarbons (HC), lead (PB), benzopyrene (BAP), etc. Their pollution to the environment is mainly manifested in the greenhouse effect, the destruction of the ozone layer, the production of acid rain, black rain and other phenomena.

The harm to the human body is mainly manifested in causing various diseases, seriously damaging the respiratory system, and has strong carcinogenicity. Prevention and control of automobile exhaust pollution: 1. Improve fuel quality.

2. Research and development of new power units:

3. Improve the structure and performance of existing automobile engines 4. Strengthen administrative management to reduce and eliminate the pollution of automobile exhaust to the atmospheric environment.

With our company's new vehicle exhaust electronic controller.

Vehicle exhaust pollution is environmental pollution caused by the exhaust gases emitted by automobiles. The main pollutants are carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, lead-containing compounds, benzopyrene and solid particulate matter, which can cause photochemical smog.

In addition, carbon dioxide (CO2), sulfide SOx (SO and SO2), nitrogen oxides (NOx and NO2), and hydrochlorofluorocarbons (HCFCs) emitted by automobiles have exacerbated atmospheric environmental problems such as the greenhouse effect, ozone layer depletion, and acid rain. CO, NOX, SOX, unburned hydrocarbons HC, particulate matter PM and odorous gases emitted by automobiles pollute the air, which is very harmful to humans, animals and plants.

There are many, such as: 1. The production of clean fuels, the current ethanol gasoline and the improvement of gasoline labeling, etc., are all measures to reduce fuel consumption and pollution; 2. Improve combustion efficiency. There are also many specific measures, such as engine stratified combustion technology, EFI technology, CVVT technology, etc.; 3. Install a three-way catalytic converter. Wait a minute.

1.Promote the use of ethanol gasoline.

2.Install a car exhaust gas converter.

3.Develop new energy sources to replace oil.

4.Improve combustion efficiency.

At present, the exhaust aftertreatment system of most gasoline engines adopts three-effect catalytic converter, and the technology has matured after years of development and application. However, with the application of lean combustion technology for gasoline engines, it has brought new problems about how to reduce NOx emissions under oxygen-rich conditions. One of the technologies is selective catalytic reduction, that is, the use of selective catalytic reducing agent to reduce NOx under oxygen-rich conditions, but this method has low conversion efficiency, poor water resistance and thermal stability, which is not conducive to large-scale application.

Another technique is the adsorption reduction catalytic method, which can maintain a high NOx conversion efficiency over a wide temperature range, but is sensitive to the sulfur content in the fuel. Due to the general low quality of oil products in China, the technology of the rear division of the lean-burn gasoline engine needs to be further developed and improved.

First, it will become a new spine to accommodate energy vehicles, second, limited number travel, third, it will issue subsidies for public transportation, fourth, it will encourage public transportation, and fifth, it will increase subsidies for electric branch travel vehicles.

1.There can be a variety of trees, the tail gas is mainly carbon monoxide, and the trees can be cracked by the slag of the beam hall for photosynthesis and absorb it. 2.It is possible to study the new automobile industry and solve the problem fundamentally.

Summary. Hello, dear <>

There are 5 types of measures for vehicle emission control; Three-way catalytic converter: It is the most mainstream emission processor at present, which can convert harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction; Second; Exhaust gas recirculation: Generally installed inside the engine, the main purpose is to reduce nitrogen oxides (NOx) in the exhaust gas and improve fuel economy at partial load.

Measures to control vehicle emissions are:

Third; Activated carbon tank evaporation control system: It is mainly to prevent the fuel vapor in the fuel pipe from leaking into the atmosphere to pollute the environment, collect gasoline vapor and send it to the intake pipe in a timely manner, mix with the air and enter the engine for combustion, and improve the economical control technology of fuel; Fourth; Particle trap: It is very common in China VI models, installed on the exhaust pipe of the diesel engine, and when the exhaust passes, the particles are diffused, intercepted, inertial collision and gravity settled, and captured, so as to purify the exhaust particles; Fifth; Electrostatic Particle Trap:

It is mainly installed on the high-end models of China VI, which is a relatively new technology, which is a higher technical level than the particle trap;

1. Raise the standards for the use of automobiles and prohibit some heavily polluting vehicles from being on the road.

2. Conduct exhaust gas testing on automobiles every year.

3. Afforestation.

Fourth, promote clean energy and electric vehicles.
