In recent years, with the rapid development of the motor vehicle economy, the production and use of motor vehicles have increased rapidly, and the environmental pollution caused by motor vehicle exhaust has become increasingly serious. The air pollution in many large cities has shifted from coal burning to a mixture of coal burning and motor vehicle pollution. The harm of motor vehicle exhaust pollution to the environment and people's health is already quite serious. Automobile exhaust contains carbon monoxide, nitrogen oxides, and other solid particles that have adverse effects on human health, causing great harm to human health. The following specific analysis of harmful substances in automotive exhaust:

1. Carbon monoxide

Carbon monoxide binds to hemoglobin in the blood 250 times faster than oxygen. Carbon monoxide enters the blood circulation through the respiratory tract, and after affinity with hemoglobin, generates carboxyhemoglobin, thereby weakening the ability of the blood to deliver oxygen to various tissues, harming the central nervous system, causing dysfunction in people's senses, reactions, understanding, memory, and other abilities. In severe cases, it endangers the blood circulation system, leading to life hazards.

2. Nitrogen oxide

Nitrogen oxides mainly refer to nitric oxide and nitrogen dioxide, which are harmful gases to the human body, especially to the respiratory system. Exposure to air with a nitrogen dioxide concentration of 9.4 mg/m3 for 10 minutes can cause respiratory dysfunction in adults

3. Hydrocarbons

It is not yet clear about its direct harm to human health. However, when nitrogen oxides and hydrocarbons are exposed to the sun's ultraviolet rays, they produce a irritating light blue smoke that contains a variety of complex compounds such as ozone, aldehydes, and nitrates. The prominent harm to the human body is to stimulate the mucous membranes of the eyes and upper respiratory tract, causing redness and swelling of the eyes and pharyngitis.

4. Solid suspended particles

The composition of solid suspended particles is very complex and has strong adsorption capacity. Solid suspended particles enter the lungs of the human body with respiration and remain in different parts of the respiratory tract through collision, diffusion, deposition, etc., causing respiratory diseases. When suspended particles accumulate to a critical concentration, they can trigger the formation of malignant tumors. In addition, suspended particles can also directly contact the skin and eyes, blocking hair follicles and sweat glands in the skin, causing dermatitis and conjunctivitis, and even causing corneal damage.

5. Lead

Lead is a toxic heavy metal element. Most automotive oils are mixed with the explosion-proof agent tetraethyl lead or methyl lead. The lead and its compounds generated after combustion are toxic substances. More than 60% of the lead in urban air comes from the combustion of leaded gasoline in automobiles. Excessive levels of lead in the human body can lead to cardiovascular diseases, and affect the functions of important organs such as the liver and kidneys, as well as the nervous system. Due to the high lead dust ratio, it usually accumulates in the air at a height of about 1 meter, which poses a significant threat to children.

Reduce travel, live a low-carbon life, and provide a fresh atmospheric environment for the planet. Each of us should make efforts to achieve it. Especially for vehicles with excessive exhaust emissions, as drivers and passengers, you and your family are the first smokers of harmful gases! For yourself and your family, it is also important to maintain your vehicle regularly. Maintaining your car in good working condition is an effective way to reduce harmful gas emissions.

Exhaust gas purification is the starting point for vehicle maintenance. Qualified exhaust emissions from motor vehicles indicate that the engine burns well and operates well. It is not difficult to achieve this, just regularly clean the carbon deposits in the intake port, fuel injector, combustion chamber, oxygen sensor, and three-way catalytic converter.

The above is an introduction to the hazards of automobile exhaust gas. If you want to learn more about exhaust gas treatment products, M-station equipment, and automobile exhaust gas treatment, please consult our company.
