What are the environmental hazards caused by incomplete combustion of fuel entering the engine cylin

The main harmful substances emitted by engine exhaust are carbon monoxide, hydrocarbons, nitrogen oxides, and insufficient fuel combustion will cause these substances to be emitted into the atmosphere without being purified.

If it is a simple hydrocarbon compound, it will produce CO and carbon dust, which is harmful to the human body. If the fuel also contains impurities such as nitrogen and sulfur, harmful gases such as SO2 and NO will be generated. In addition, incomplete combustion may also produce some more complex substances, which may be harmful to the human body.

Refers to a combustible substance. According to the state of the substance, it can be divided into solid fuels, such as: coal, oil shale and coke, the product of coal processing, etc.; Liquid fuels, such as petroleum and its processed products, gasoline, diesel, etc.; Gaseous fuels such as coal gas, natural gas, etc.

In addition, there is nuclear fuel, which emits enormous heat from nuclear reactions. Fuel plays an important and indispensable role in industrial and agricultural production, transportation and people's lives.

Fuels are widely used in industrial and agricultural production and people's lives, and can release energy through chemical reactions. There are many types of fuels, the most common being coal, coke, natural gas, and biogas.

With the development of science and technology, human beings are developing and using fuels more rationally, and trying to pursue the concept of environmental protection. Fuel is also a part of physics that needs to be studied, and its formula for heat absorption and release is q=q m.

Incomplete combustion of the mixture can be caused.

1. The mixer with serious carbon deposition inside the engine, low engine efficiency and incomplete combustion is easy to deflagrate and damage the cylinder inner wall, affecting the life of the engine and the whole vehicle.

2. Poor fuel economy and rising fuel consumption.

3. The discharge exceeds the standard, resulting in three-way catalytic blockage. Pollute the environment and affect human health.

Carbon deposits damage the catalytic converter causing the vehicle to decrease power, increase fuel consumption, reduce life, etc.

The gas distribution phase and ignition timing are wrong, and there is a lot of carbon deposit, which is obviously not enough power, high fuel consumption, large vibration, and fire. This situation has not been in place for 2 years, and the pit station has to deal with it.

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. The following is about other hazardous substances and how to prevent them:

Other harmful substances: In addition, carbon dioxide (CO2), sulfur-containing compounds SOX (SO and SO2), nitrogen oxides NOx (NO2), and hydrochlorofluorocarbons emitted by automobiles have exacerbated atmospheric environmental problems such as the greenhouse effect, ozone layer depletion, and acid rain. The air polluted bodies such as CO, NOX, SOX, unburned hydrocarbon HC, particulate matter PM, and odorous gases emitted by automobiles are very harmful to people, animals, and plants.

Preventive measures: Strengthen the supervision and law enforcement of environmental protection. Strengthen the daily supervision and law enforcement inspection of environmental protection production of motor vehicle enterprises, standardize inspection behavior, increase the proportion of spot checks, and control the source of new vehicle emissions.

Continue to carry out special actions to inspect the consistency of environmental protection production of motor vehicles, and adopt a combination of on-site inspections of enterprises and random inspections of market supervision to severely crack down on production behaviors that violate environmental protection laws and regulations.

Summary. We are pleased to serve you, the emission pollutant mainly affected by the combustion temperature in the cylinder is CO, and the generation of CO in the exhaust of the car is caused by the insufficient combustion of fuel in the cylinder, which is an intermediate product generated by the lack of oxygen. The formation mechanism and influencing factors of the main pollutants CO, HC, NOx and particulates in automobile exhaust.

Dear, I hope mine can help you!

Waste gas contains harmful ingredients to people, animals and plants, such as sulfur dioxide, nitrogen dioxide, etc., different waste gas contains different harmful substances, but will pollute the air and cause harm to the environment. Therefore, it cannot be directly discharged into the air. Now advocating a low-carbon life and using less private cars is to reduce carbon dioxide emissions, thereby slowing down the greenhouse effect such as global warming.

The exhaust gas mainly includes sulfur dioxide and other components. SO2 is an air pollutant, mainly from the combustion of coal, oil and natural gas, it remains in the atmosphere for about a week and then becomes SO3, SO3 is easy to form sulfuric acid mist with moist air, and acid rain is formed when humidity and air pressure change. Acid rain is extremely harmful to nature and human beings, and more than 20 provinces, municipalities and autonomous regions in China have experienced acid rain of varying degrees, and the annual loss of agriculture, forests and construction due to acid rain can reach 40 billion yuan.

In fact, generally speaking, the early engines were directly discharged into the atmosphere, but now human beings pay more attention to air pollution, so there are emission standards, so they need to be treated before they can be discharged.

Generally, it is in-line, such as trucks, tractors and other machinery, although there is pollution, but the cost of these machines do not have a filter device.

Fossil fuel combustion can produce carbon monoxide, carbon dioxide, sulfur dioxide, inhalable particulate matter and other substances Carbon dioxide is a major gas of the greenhouse effect, and excessive content in the atmosphere can easily lead to the greenhouse effect Acid rain is easy to form after the interaction of sulfur dioxide and water, which can corrode buildings, destroy plants, and acidify soil

Carbon monoxide is toxic and can easily poison people, and inhalable particulate matter can also cause harm to the human body

When the combustion is not sufficient, carbon monoxide, sulfur dioxide, a large amount of dust, nitrogen oxides, hydrogen fluoride and so on are produced.

Car exhaust gases are:

1. Hydrocarbons.

2. Carbon monoxide.

3. Lead 4. Nitrogen oxides.

5. Particulate matter.

6. Sulfur dioxide.

Among them, it is most closely related to insufficient combustion.

1) Gasoline and diesel are both products of petroleum processing, and when separated, they are prepared according to their different boiling points in the pie, so petroleum belongs to the mixture

2) Incomplete combustion of automobiles and diesel fuel oil contains a small amount of carbon monoxide in the exhaust gas.

Carbon monoxide and hemoglobin.

Combined to poison people

Answer: (1) Oil; 2. Carbon monoxide.
