Autumn and winter seasons have arrived, and the haze has come as usual. The person who drives has started to tangled and can he still open the window for ventilation?
The correct answer is: Whether it is not hazy days, as long as the car in the city, it is best not to drive the window, and must be careful not to open the fan in the outer circulation mode.
When driving in a city, the air quality in the car is not that beautiful. The University of Surrey in the United Kingdom has done a special experiment on this, and the result is: If you run into a traffic jam when driving, or if you stop at a red light, the air quality in your car will deteriorate significantly. Especially during the period of red light, the rise of inhalable particulate matter in the vehicle (that is, all types of PM that people enjoy, such as PM1, PM2.5, and PM10) is quite frightening, and can reach 29 times of the smooth flow of traffic. many.
The countermeasures given by the experts are: if the temperature is right, close the windows and turn off the fans; if you need to use air conditioners, you have to hit the inner circulation mode.
According to tests conducted by the British University’s scientific research team, when the air quality in the car was the worst, the windows were closed and the fans were driven in the external circulation mode. Fans constantly pump the dirty air outside the vehicle into a closed compartment, turning this small space into a tiny “poison chamberâ€.
It's an exaggeration to say this, but in the city's traffic, the air quality in the car is indeed a big problem. In the case of congestion, the vehicle speed is slow, the engine operating conditions are poor, the combustion efficiency is low, and the exhaust gas exhausted is heavy and concentrated; if it hits a red light, the vehicle slows down and stops, and then starts and accelerates after turning on the green light. The engine is discharged during this process. The exhaust gas is rich in connotation and there is absolutely no cutting corners.
The streets in the city, especially the densely trafficked streets, are filled with various toxins and various specifications of PM in the car exhaust, which poses a great threat to the health of the driver. In addition to closing windows and fans, the research team at Surrey County University came up with the idea that as far as possible following the car, it should be far from the front car and get too close to the car’s buttocks in front of the car. A bit of rear-end risk.
Closing the windows, shutting down the fans, or keeping the air supply system inside the car in circulation, the air quality in the car is the best. According to the test of the University of Surrey, this can reduce air pollution in the car by about 76%. degree.
Unfortunately, we can't copy these experiences simply because our city is not only heavily congested, but there are also two special products: "gas car" and smog.
In the past few years, there have been many reports of “toxic gas vehiclesâ€. The interior of the car also releases a variety of toxic gases. No matter if it is a luxury car or a cheap car, it has been exposed. This makes us very embarrassed, do not open the window ventilation, the car interior poisoning; open the window ventilation, outside the fog and car exhaust take advantage of.
Fortunately, smog increased in autumn and winter, when the temperature is relatively low, the toxic substances in the vehicle are not so embarrassing. Therefore, we have an expedient plan: Before getting on the bus, open the door and let the wind pass through to disperse the poisonous gas in the car. After getting on the bus, close the window and adjust the air circulation mode to the inner circulation to prevent the outside of the car. Dirty air enters the car.
In this way, after our strong lungs have absorbed and absorbed the remaining haze in the car, we can have a chance to breathe. After all, the toxic gas in the car interior will take a while to reach a certain concentration. In this precious time period, we Maybe it will be the destination.
Remember, as long as you drive in the city, close the windows, open the fans less, and use the inner circulation mode. There is only so much we can do, and the rest will do nothing.
Even if it is not hazy, even if the air looks good, drive on the roads of the city, do not open the windows, do not use the outer cycle, because each car is constantly exhausted, the air quality on the motor vehicle lane It's really bad.
King's College conducted a special study and found that the ambulance driver in London was affected by air pollution, which was even greater than the courier courier riding a bicycle. The reason is that the dense exhaust on the motor vehicle lanes is better on non-motorized lanes.
The World Health Organization has issued ten major threats to human health. In addition to our familiar high blood pressure, smoking, and alcohol, air pollution is also among them. Everyone drives the car every day. The air on the road and in the car is also a crisis. You are still a good idea.
Finally, remind you that the air-conditioning filter on the car should be replaced frequently. This is an important step in maintaining the air cleanliness of the car.
