Measures taken by people to prevent air pollution from automobile exhaust

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.

The measures taken to control automobile exhaust include: mandatory scrapping of old vehicles, mandatory promotion of electric injection vehicles, mandatory use of unleaded gasoline, mandatory installation of three-way catalytic converters and other powerful measures, so that automobile exhaust emissions can be controlled to a certain extent.

Automobile exhaust contains hundreds of different compounds, including suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. A car emits harmful exhaust gases three times more than its own weight in a year.

When the car is overloaded, driven at a slow speed or running in neutral gear, the fuel cannot be fully burned, and the carbon monoxide content in the exhaust gas will increase significantly. Carbon monoxide is a colorless, odorless, asphyxiating toxic gas with low chemical reactivity capacity, and its relative density to air is very small.

After carbon monoxide enters the human blood from the respiratory tract, it will combine with the red blood protein Hb in the blood to form carboxyhemoglobin, resulting in a decrease in oxygen-carrying capacity and causing the human body to react, such as hearing will be damaged due to the lack of oxygen to the cochlear nerve cells in the ear.

Inhaling too much carbon monoxide can cause shortness of breath, purple lips, difficulty breathing, and even death. Studies have shown that a person's tolerance for carbon monoxide is quite high, and a healthy person can withstand the attack of carbon monoxide in the blood at 20% to 40% in a short period of time. Although the threshold for carbon monoxide has not been determined, long-term absorption of carbon monoxide is a potential threat to the health of urban residents.

Generally, exhaust gas emission facilities will take a lot of measures, such as desulfurization, and an exhaust gas treatment device that is sold out.

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.

The air pollution caused by car exhaust is a public nuisance. Public nuisance refers to the harm to the public and society caused by undesirable factors of human activities, such as air pollution.

Water pollution, soil pollution, noise, vibration, foul odor, land subsidence and other harmful consequences.

Air pollution from car exhaust belongs:

Carbon monoxide is the main polluting product emitted by automobiles.

Hydrocarbon compounds, nitrogen oxides, sulfur dioxide.

Lead-containing compounds, benzopyrene.

and solid particulate matter, as well as photochemical smog.

The prevention and control of automobile exhaust pollution can start from three aspects: one is to strengthen the improvement of automobile technology and reduce exhaust pollution, the second is to use administrative management means to improve automobile exhaust emission standards, and the third is to improve the use of vehicles.

Air pollution refers to the phenomenon that certain substances enter the atmosphere due to human activities or natural processes, present sufficient concentrations, reach sufficient time, and can endanger human comfort, health or the environment.

3. Afforestation.

Fourth, promote clean energy and electric vehicles.

Industrial air pollution.

There are many kinds of substances, including soot, sulfur oxides, nitrogen oxides, organic compounds, halides, carbon compounds, etc. Some of them are soot, and some are gases.

2) Stoves and heating boilers: A large number of civil stoves and heating boilers in the city need to consume a large amount of coal, and the coal will release a large amount of dust, sulfur dioxide, carbon monoxide, and other harmful substances to pollute the atmosphere during the combustion process. Especially in winter, when heating, it often fills the polluted area with smoke and chokes people's cough, which is also a source of pollution that cannot be ignored.

3) Transportation: Automobiles, trains, airplanes, and ships are the main means of transportation in contemporary times, and the exhaust gases produced by burning coal or oil are also important pollutants. In particular, the number of cars in the city is large and concentrated, and the pollutants emitted by the exhaust can directly invade people's respiratory organs, which is very serious to the air pollution in the city, and has become one of the main sources of air pollution in large cities.

The exhaust gases emitted by automobiles mainly include carbon monoxide, sulfur dioxide, nitrogen oxides and hydrocarbons, and the first three substances are very harmful.

4) Smoke from forest fires.

(1) Both are composed of two elements and both contain oxygen (2) Carbon dioxide is a molecule composed of different elements, while nitrogen is a molecule composed of the same element (3) 2CO 2NON2 2CO2 15 22 (4) The type, number and mass of atoms in chemical changes have not changed (other reasonable answers are also acceptable) (1) According to the diagram, it can be seen that a, b, C and D are NO, CO, CO2 and N2 respectively, and NO, CO and CO2 are all oxides and contain oxygen. (2) Carbon dioxide is a molecule composed of different elements and belongs to chemical compounds, while nitrogen is a molecule composed of the same element and belongs to elemental substances. (3) Write the chemical equation directly according to the diagram.

4) According to the law of conservation of mass, the type, number, and mass of atoms do not change during chemical change, and the type and mass of elements do not change, only the type of matter and the type of molecule change.

Smog comes from a variety of sources, such as vehicle exhaust, industrial emissions, construction dust, garbage incineration, and even volcanic eruptions. However, the degree of action of different pollution sources varies in the haze weather in different regions.

Smog has been around since ancient times, and human activities or natural phenomena such as slash-and-burn farming and volcanic eruptions can lead to haze weather. However, after mankind entered the fossil fuel era, smog weather really threatened the living environment and health of human beings. Rapid industrialization and urbanization have led to rapid energy consumption, high population concentration, and ecological and environmental damage, all of which have laid the groundwork for the formation of haze weather.

The formation of haze has both "source" and "**", which is not conducive to the meteorological conditions of pollutant diffusion, once pollutants accumulate in static meteorological conditions for a long time, it is easy to form haze weather. There are three elements to smog formation:

The first is the physical base source for the generation of particulate dust. China has the largest Loess Plateau in the world, and its soil texture is the most prone to the formation of particulate dust particles.

The second is the dust caused by poor movement. For example, if mud flows onto the road after rain or splashing water on the flower beds in the middle of the road and on the corner of the street, after an hour of drying, it will be spun by the wheels and cause a lot of dust, and even if the particulate matter falls back to the ground, it will be thrown over the city again because cars continue to drive by.

Third, the dust-based source and the motion difference process are concentrated in a certain spatial range, and the particles eventually accumulate with the water molecule nodules to form haze. At present, among the more than 350 cities in the Loess Plateau region of China, the stock of the three elements of haze structure is quite abundant, and the United States imports Puwei Xintiancat.
