How to control air pollution caused by car exhaust?

1. Switching to automobile fuel (1), using unleaded gasoline to replace leaded gasoline, which can reduce the emission of toxic substances in gasoline exhaust (2), mixing additives, and changing fuel composition. (3) Select appropriate lubrication additives and mechanical friction modifiers. (4) The use of green fuel can also reduce the toxicity of automobile exhaust.

Engine debugging (1) to reduce the injection advance angle. Reducing the injection advance angle reduces the maximum operating temperature of the engine (1500 degrees Celsius) and reduces the amount of NOx generated. (2)..

Purification measures (i.e., vehicle exhaust from the original toxic gas, into non-toxic gas, and then discharged into the atmosphere. Thus it can be reduced.

Vehicle exhaust emissions refer to the emission of harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot) from vehicle exhaust.

Main components: Carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOX) and some other solid particles that have adverse effects on the human body, especially leaded gasoline, are more harmful to the human body. Lead is particulated in the exhaust gases and diffuses with the wind.

Gasoline is mainly composed of carbon and hydrogen, and when gasoline is burned normally, it produces substances such as carbon dioxide, water vapor, and excess oxygen. However, due to the fact that the fuel contains other impurities and additives, and the fuel often cannot be burned completely, some harmful substances are often discharged. There are more than 100 types of vehicle exhaust composition, and the main pollutants include carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx).

The global warming effect, the temperature rises, the icebergs melt, the ozone layer thins, and ultraviolet rays will harm people's health!

The car makes it convenient for us to travel, but everything is made of two sides, which brings us convenience and produces car exhaust at the same time, which causes serious pollution to the air.

First, let's take a look at the main components of car exhaust:

1.The main components in car exhaust are carbon monoxide, hydrocarbons, nitrogen oxides, carbon dioxide, sulfur dioxide, lead, and some particulate matter.

2.The substances that can pollute the environment in automobile exhaust are carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, lead-containing compounds, and some particulate matter.

Secondly, let's take a look at the hazards caused by automobile exhaust to our living environment

1.Particulate matter: If the vehicle exhaust emissions exceed the standard, harmful particulate matter will be discharged, and these particles have a strong adsorption capacity and can adsorb various metal dusts and various carcinogens.

If the air is filled with a large amount of particulate matter, it can cause inflammation and conjunctivitis, and can cause cancer at worst.

2.Carbon monoxide: The emission exceeds the standard because the exhaust gas contains carbon monoxide, which will weaken the oxygen delivery function of the blood after being inhaled by the human body, thus causing hypoxic damage to people.

3。Greenhouse effect: The greenhouse effect is a global public hazard, in which the emission of automobile exhaust is one of the important causes of the greenhouse effect. The greenhouse effect causes global warming, which in turn causes a series of problems, such as melting glaciers and changing species.

After understanding these, let's talk about how to effectively prevent and control automobile exhaust pollution

Green travel: Low-carbon and environmentally friendly travel is the best way to effectively reduce the increase of automobile exhaust and reduce the greenhouse effect.

Three-way catalytic converter: The use of three-way catalytic converter can decompose the harmful substances in automobile exhaust to a large extent, and greatly reduce the air pollution caused by automobile exhaust.

Planting more trees: Trees can effectively purify the air, but they only purify the air to a certain extent, and their ability is limited.

Development of new energy: The development of new energy and green energy can help us reduce pollution to the environment. Such as: tidal energy, wind energy.

the use of clean energy to replace fuels such as petroleum in a targeted manner;

vigorously promote new energy vehicles;

Planting more trees and planting trees on roads where cars pass to purify the air.

If you want to prevent and control automobile exhaust pollution, then you can design the car as a new energy vehicle, and vigorously promote new energy vehicles.

We reduce the number of gasoline cars so that we can control the exhaust of the car, and now our cars have new energy vehicles.

The following measures should be taken:

1. Reduce pollutant emissions. Reform the energy structure, use more non-polluting energy sources (such as solar energy, wind energy, hydropower) and low-pollution energy (such as natural gas), pretreatment of fuels (such as desulfurization before coal burning), and improve combustion technology can reduce emissions. In addition, before the pollutants enter the atmosphere, the use of dust and smoke removal technology, condensation technology, liquid absorption technology, treatment technology, etc. to eliminate some pollutants in the exhaust gas can reduce the number of pollutants entering the atmosphere.

2. Control emissions and make full use of atmospheric self-purification capacity. Different meteorological conditions will have different capacities for pollutants in the atmosphere, and the same amount of pollutants will be discharged, resulting in different concentrations of pollutants. For areas and time periods with strong winds, good ventilation, turbulence and strong convection, the atmospheric diffusion and dilution capacity is strong, and more factory and mining enterprise activities can be accepted.

In areas and time periods of temperature inversion, the diffusion and dilution ability of the atmosphere is weak, and more pollutants cannot be accepted, otherwise it will cause serious air pollution. Therefore, emissions should be effectively controlled in different regions and at different times.

3. The site selection, chimney design, urban and industrial zone planning should be reasonable, and the large emitters should not be overly concentrated, and the repeated superimposed pollution should not be caused to form serious local pollution incidents.

1. Take public transportation as a daily means of transportation, such as cycling or walking, to reduce the use of vehicles and reduce exhaust emissions.

2. If it is unavoidable to use a private car, please make sure that your driving speed is within the range of valid regulations. When not traveling, reduce red light as much as possible and turn off the engine when not in use to ensure that the car is less polluted.

3. Some automakers use advanced technologies to reduce vehicle emissions, such as purchasing clean fuel.

4. Adopt the practice of "carpooling" and take turns using your car with your neighbors or work partners. This measure can be relatively effective in reducing vehicle pollution.

5. The use of alternative energy sources, such as solar energy and wind leakage hidden energy, they are more effective in protecting the environment.

6. Save energy, use energy-saving appliances properly, and do not waste electricity, which helps to control air pollution. Smaller energy demand will reduce the amount of air pollution caused by power plants.

7. Do not incinerate the garbage generated at home, but resort to other garbage disposal devices. For example, the disposal of garden waste. The best thing to do is to opt for traditional methods such as composting.

8. You can also use technologically advanced air pollution control equipment systems, such as filters to remove dust, or wet scrubbers to remove acid gases from the air. But in any case, the use of a thermostat in the home lounge is not necessary.

This gas emission not only smells weird, but also makes people dizzy, nauseous, and affects people's health. In the case of not many vehicles, the self-cleaning ability of the atmosphere can still dissolve the toxins discharged by the car. But with the rapid increase in the number of cars, traffic congestion has become commonplace, and the advantages of convenience, comfort and efficiency that cars should have are gradually offset by too many vehicles.

The "automobile disaster" has been formed, and the resulting automobile exhaust is even more harmful. Scientific analysis has shown that automobile exhaust contains hundreds of different compounds, including solid suspended particulates, 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.

The British Association for Clean Air and Environmental Protection has published a study [2] that 10 times more people die from air pollution each year in the UK than traffic accident victims. If you still have to wear a mask when you go out, Puweixin has Tmall imported from the United States, which can be effectively filtered.

Regarding the landlord's concern about "what to do with car exhaust pollution?" "The following manuscript search is my personal opinion:

A good solution to automobile exhaust pollution:

1. Clean up the carbon deposition of the car, the serious carbon deposition of the car will affect the circuit blockage of the car, so that the car will have the phenomenon of exhaust gas not up to standard, so people should regularly clean up the rest of the car;

2. Air filterAir filter, as the name suggests, is to prevent polluting particles in the air from entering the cold air system of the car, and the number of lines in the car does not affect the normal operation of the parts of the car. After the car has been used for a long time, the air filter also needs to be cleaned regularly, and after the air filter is cleaned, the pollutants in the air can be effectively avoided, so that it will not affect the performance of the car key, so that the pollutants and impurities emitted in the car exhaust will be less, and the phenomenon of the car exhaust gas not meeting the standard can be avoided;

3. Mixing additives, changing the fuel composition of gasoline with less than 15% methanol fuel, or using water gasoline fuel containing 10% water, can reduce or eliminate the pollution effect of CO, NOX, HC and lead dust to a certain extent.
