【Car owner's car knowledge]A few days ago, a photo of Harbin before and after the smog appeared on Weibo. After reading it, I can’t help but worry. This is even more serious than Beijing! Then, in a city with severe smog, car owners should How to prevent pollution in the car?
What's the haze:
When many people talk about smog, they blame the problem on the emission of automobile exhaust. What's more, some experts blame the smog on domestic cooking methods.
In fact, "fog" and "haze" are two concepts. Fog is caused by water vapor, and haze is a cloudy image formed by a large amount of smoke, dust and other particles suspended in the air. In other words, the word smog has little to do with fog. The smog that people are talking about is actually a mist formed by suspended dust in the air. The main causes of smog are untreated industrial waste gas and yellow-label vehicle exhaust emissions.
Several ways to deal with smog
1. Reduce travel on hazy days
In moderate haze weather conditions, unnecessary outdoor activities should be reduced. When visibility is poor, traffic safety should be paid attention to, the windows should be opened as little as possible, and the windows should not be used for ventilation during driving.
2. Open the sunroof
Experiments have proved that the exhaust gas of automobiles is mainly concentrated at a height of less than 80cm above the ground, and the density of automobile exhaust gas is much lower at a height of more than 1 meter. The height of the car sunroof is flush with the roof, and most of them are more than 1.4 meters, so even in traffic jams, the air coming in from the sunroof is much cleaner than that from the side windows.
3. Reasonable selection of internal and external circulation
Because the vehicle is equipped with air conditioning inside and outside circulation mode. When the road conditions are good and the air is fresh, citizens can use the external circulation mode, and when the road is congested and the exhaust emissions are serious, the internal circulation mode is used.
4. Buy an in-car purifier
With the use of the air purifier in the car, the principle is the same, and the air filter inside the purifier is used to filter the air. In fact, the large environment outside the car is polluted. After the small environment inside the car is purified, it has little effect. After all, you can't stay in the car all the time. Once you open the window or open the door, the previously purified air will be polluted again.
5. Regularly clean the air conditioning system
To improve the air quality in the car, the most fundamental way is to clean the air conditioning system. "Regularly clean the air conditioner's pipes, and use maintenance products for indoor sterilization, such as air conditioner cleaners.
6. Bathe in the sun
In winter, most car owners close the car windows tightly every day, fearing that a little wind will enter the car. In fact, this near-closed environment is very easy to breed bacteria, thus affecting the health of the people in the car. Therefore, when the car is parked, the car owner can put the car in the sun, and then open the windows for ventilation, which can not only achieve the sterilization effect, but also make the air in the car clear.
7. Reduce smoking in the car
An experiment has proved that the PM2.5 pollution index produced by smoking a cigarette in a closed car is above 4000 units, which is hundreds of times different from the PM2.5 before smoking. Therefore, reducing smoking in the car is an important reason to ensure a bad environment in the car.
