Carbon Monoxide Sensor Prevents Application of CO Intoxication in Automotive Air Conditioning

As the temperature drops, the air conditioning in the car also comes in handy, but some people are accustomed to sleeping in the car with air conditioning, and doing so is extremely dangerous. In fact, there are events in the country where sleeping in the car occurs every year throughout the country.
Now, the sealing performance of automotive windows and doors is very good. Under the condition of stopping the vehicle, the carbon monoxide emitted by the engine for a long time may gather in the car and mix with the carbon dioxide exhaled by the people in the car, resulting in the reduction of oxygen. Over time, carbon monoxide poisoning was unknowingly caused by people in the car.
Interview: Li Yanwei, Deputy Director, Department of Internal Medicine, Boxing County Traditional Chinese Medicine Hospital Carbon monoxide is a colorless, odorless gas. People simply do not feel it. After the carbon monoxide enters the body, the hemoglobin's ability to absorb oxygen declines, harming the nerve center of humans. Causes human feelings, reactions, understanding, and other dysfunctions.
In an oxygen-deficient environment, 6 minutes will cause the brain to irreversibly die. Over a period of more than 30 minutes will cause the heart to die of ischemia and hypoxia.
Interview: Li Yanwei, deputy director of the Second Internal Medicine Department of Boxing County Traditional Chinese Medicine Hospital , even after carbon monoxide poisoning, even if it can feel dizziness and nausea, it will be difficult to save itself because of weakness in the limbs. If you turn on the air conditioner while sleeping in the car, you will feel even less. Due to the airtightness of the interior space and limited oxygen, people's exhaled carbon dioxide will increase the carbon dioxide content of the vehicle to a certain extent, and it will also make people enter a coma.

How does carbon monoxide enter the car?
So how does carbon monoxide get into the car? How much do you know? Check the reporter's investigation.
Interview: When a certain auto repair shop technician Shen Wei is running, the engine speed is 1500-3000 revolutions per minute, and there will be no excess carbon monoxide in the discharged exhaust gas. However, when the engine is idling at idle, exhaust gas containing a large amount of carbon monoxide tends to be generated because the combustion of gasoline is insufficient.
In addition, the car itself is not a completely enclosed space, but if the car is still open after stopping, the carbon monoxide discharged from the engine may gradually accumulate in the car, and the people in the car will consume oxygen and emit carbon dioxide for a long time. Those who rest in the car will unknowingly lose consciousness due to poisoning, and they will lose their lives when the situation is serious.
Interview: Some auto repair shop technician Shen Wei's carbon monoxide may also enter the trunk, so whether the air conditioning is adjusted to the inner or outer cycle, carbon monoxide will enter the car through the gap.
Driving warm wind in winter is not as good as summer. Sometimes the speed is slow, but the effect is not good. Of course, the main reason is that the owner does not open the way. What is the correct way to open the warm air in winter?
Interview: Hong Bo auto repair technician Shen Wei, if he is eager to open the air conditioner warm air heating will consume the battery's power, to be opened after the vehicle can be used to power generator. The correct way is to start the engine warm-up first, wait for the engine temperature pointer to the middle position and then turn on the warm air, and set the air circulation as the outer circulation so that the cold air in the car is discharged outside the car, and wait for 2-3 minutes. The air circulation is set to internal circulation.
