What are the correct ways to drive in winter to remove fog?

1. Intermittent fenestration.

Open the windows for convection, and if you have a sunroof, you can also open the sunroof to balance the temperature inside and outside the car, and the fog will disappear automatically. But you have to endure the cold, after all, it takes a bit of courage to drive a window in winter.

2. Air conditioner cold air.

The effect of cold air defogging is very fast and direct, turn on the refrigeration switch of the air conditioner in the car, turn on the external circulation, and blow the air outlet against the air conditioner to the glass to prevent water vapor condensation and play a defogging effect. But the cold wind in the winter is really uncomfortable, so it can only be used urgently.

3. Air conditioning and heating.

In addition to the cold air, turning on the air conditioner and hot air can also achieve the defogging effect, which can not only dry the fog on the windshield, but also allow the fresh air from outside to enter the car, and you won't feel too stuffy when sitting inside. However, the effect of warm air defogging is relatively slow, and it is necessary to use hot air to blow the glass until it is dry when parking, because the fog will suddenly become larger at the beginning of the hot air, and it is best not to use it during driving.

4. Auto glass defogging agent.

You can use the car glass defogger purchased online or at the car supply store, spray it before departure, the general effect can last for 10 days, and it is also the most intuitive way to remove fog.

In addition to buying car glass defogging, you can also make it yourself, as long as the dish soap and water are diluted at a ratio of 1:10 and put in a small watering can. Spray directly on the windshield before driving, wait for a minute to dry with a rag, the fog will disappear, and it will not fog up when driving, it can generally last for more than 20 hours, and then it is guaranteed to spray, which is very practical.

5. Automatic defogging of automobiles.

Nowadays, some car air conditioners have a defogging mode, turn it on, and the air outlet under the front windshield can directly and effectively blow away the fog.

1. Reduce the temperature difference between the inside and outside of the car, and remove the cold air from the fog. Press the front windshield defogging button, adjust the air conditioning temperature to low temperature, and appropriately increase the air volume, the temperature in the car will decrease rapidly, the temperature difference between the inside and outside of the car will decrease, and the defogging effect will be immediate. But in winter, the cold wind turns on, it is too cold and swishing, and it is uncomfortable.

2. Reduce humidity, warm air drying and defogging Press the front windshield defogging button to adjust the air conditioning temperature and air volume to the maximum. At first, due to the large temperature difference, the fog on the glass may be thicker, but after a few minutes, the water vapor in the car will be dried, and the hot air defogging effect is slower, but the temperature in the car is comfortable, so most of them choose this mode in winter.

3. Open the window for convection, open the window to reduce the temperature difference between the inside and outside of the car, but one of the drawbacks of this method is that opening the window will make the people in the car feel very cold.

4. Use a professional defogging agent, wipe the inside of the front windshield clean before using the anti-fogging agent, and then spray an appropriate amount of anti-fogging agent, and wipe it clean with a clean towel after the anti-fogging agent solidifies. The anti-fogging agent can form a water repellent layer between the water molecules and the inner surface of the glass, thus keeping the glass surface clean and preventing fogging.

Here's how:1. Windows can be opened to allow air circulation inside and outside the car.

2. Turning on the air conditioner can also remove the fog, and the removal speed can also be faster, but the temperature in the car will be lowered.

3. The owner can spray a special glass anti-fogging agent, which has a more obvious anti-fogging effect and a longer service life.

Causes of fogging while driving:

The outside temperature is high, the saturated air pressure of water vapor is large, the temperature of the glass is low, the saturation pressure of water vapor near the glass decreases, when the temperature difference is large enough, the saturation pressure is low enough, and the water is liquefied. The closer you are to the glass, the lower the saturation pressure of the water, and the easier it is for the water to liquefy.

The water molecules in the air are constantly moving irregularly. When there is no temperature difference, water molecules keep hitting the glass and flying out of the glass. Because the lower the temperature, the slower the rate of movement, so after the water molecules hit the cold glass from the hot air, the movement slows down and cannot fly out in time, while the water molecules outside are still hitting the glass, so the water on the glass is more and more, and finally gathers into small water droplets.

1. First turn on the windshield wipers to remove the fog from the outside of the car.

2. Find these two buttons on the car, one fan-shaped represents the front windshield defogging, and the square below represents the rear glass defogging.

3. Press the fan-shaped button on the potato stool, and the yellow light will turn on.

4. Put a piece of toilet paper under the front windshield, obviously see that the wind is very strong, and blow warm air to defog the glass.

5. The fog from the front windshield is removed.

6. Continue to press the defogging button of the back glass to defog the back glass.

7. The rear glass divisor travel fog is the reason for these horizontal heating wire defogging, and the front and rear glass defogging process is over.

First of all, we must understand the cause of fogging in the car, this is because as soon as we enter the car, we exhale a lot of hot air, and the outside temperature is low, and there is a difference in the temperature between the inside and outside of the car, and some fog will be generated on the glass at this time. If it rains, the air is humid, the fog will be bigger, if the temperature difference between the inside and outside of the car is not large, only a little fog, we only need to prepare a towel with better moisture absorption, wipe it gently. <>

If there is still fog after wiping it, then we turn the window down a little bit, open a gap, reduce the temperature difference between the inside and outside of the car, and the fog in the car will slowly disappear. However, this method does not work in rain or snow or on highways, and the temperature inside the car can be very low during the cold winter months. After turning on the air conditioner, using the internal circulation, and at the same time adjusting the air outlet to blow the glass slightly, the fog in the car is immediately cleared, and the effect is very good.

But the downside is that if it's winter, the temperature inside the car will also be lower, which will be poor for the ride experience. You can also use the method of warm air, you can also clear the fog in the window, adjust the switch to the warm air position, and at the same time adjust the air volume as much as possible, and also need to adjust the air outlet to blow the glass slightly, so that you can blow the fog in the car bigger for a while, so that you can dry the fog in the car, and then adjust the switch to the warm air position. But there is also a problem with this situation, that is, when it is first started, it needs to wait for the water temperature to come up before it can work, and it takes a while.

Sometimes we find that the side windows also fog up, which can affect the sides of the car that we are looking at. At this time, we only need to adjust the air outlet by the side window, so as not to let it blow directly on the side window glass, which can generally be solved. If the rear gear of the car is fogged, the speed will be slower by the above methods, then we can press the fog switch, through those red lines on the rear window glass to increase the temperature of the glass, and the fog will be cleared after a while.

This switch also has the important function of defrosting and defrosting the rear window. Sometimes the outside of the front windshield will also fog up, at this time we can spray some glass water on the car to fog again, if the fog rises again, you can consider adjusting the front gear outlet and adjust it. <>

1. Open the window for convection, you can say that the windows on both sides are open to leave a gap. 2. Use air conditioning to defog and use cold in case of emergency, but in most cases, the most used is warm air. 3. Apply the defogger to the glass, wipe it several times, and then clean it to form a protective film to prevent water vapor from condensing on the glass.

Turn on the air conditioner. Fog generally occurs when the temperature difference between the inside and outside of the car is too large, so it can only be quickly defogged by reducing the temperature difference through air conditioning.

You can turn on the switch of the air volume, adjust the temperature to the hottest, and then adjust the reversing gear to the glass setting.

The defogging function of the car should be turned on, and it can be defogged instantly, which is very easy to use.

1.Open the windows to keep the temperature inside and outside the car consistent.

2.Turn on the cold air conditioner, adjust to the maximum air volume, blow only on the front windshield glass, and turn on the external circulation.

The reason for the fogging of the car window is caused by the large temperature difference between the internal heat and the external cold, which is the liquefaction of water vapor in the macroscopic sense, and the saturation air pressure in the micro sense. The outside temperature is high, the water vapor saturation pressure is large, the glass temperature is low, and the saturation pressure of water vapor near the glass is the most direct, but the effect is not very beautiful, because the requirements for wiping tools are very high, and the ordinary towel can not fully absorb the water droplets at the moment of wiping the past, so it will always leave water marks after wiping, which is very uncomfortable. And it's too dangerous to wipe the glass while driving.

When the temperature in the car is constant, the internal circulation is turned on, and no fog is generated. But there will be a lot of fog in the rear gear, which cannot be cleared. If you are driving at high speed for a long time, it is recommended to use a defogging product so that you will not be bothered by fog.

Its temperature is relatively close, and it does not form condensation. Although it is cold outside, the glass is hot, and the hot glass will not condense into this fog, the effect is better, and it is warmer, which can avoid fogging again when driving.

In winter, especially when the outdoor humidity is relatively large or people's shoes bring snow into the car, due to the temperature rise and melting, the car is moderately increased, or in winter, a few people have just finished steaming the sauna and soaked in the hot spring, as soon as they enter the car, everyone is like a small steam stove If you want to get on the car and go, no fogging, I personally recommend to buy car defogging agent online, wipe it on the front windshield and side glass in the car, after wiping, it will not fog up for half a month, and the cost is not high.

In winter, the outside of the car is cold, if the window glass is completely closed, the breathing of the people in the car and the temperature of the human body will cause the air temperature in the car to rise, and the air humidity will become larger and larger, at this time, the humid and hot air in the car will condense a small water when it encounters the cold glass, because the air conditioning in the car is turned on, the temperature in the car is low, and the external air is moist and hot, so it is easy to cause the outside of the glass to fog up.

If you want to quickly remove the fog when driving in winter, you need to turn on the air conditioner, turn on the air conditioner for a few minutes, and the fog will disappear soon, and it will be good when the temperature in the car rises.

I think if you want to do a quick defogging when driving in winter, you can turn on the heating in the car first, and then turn on the internal and external ventilation, so that you can slowly defog it.

If the vehicle has just started and the water temperature has not risen, turning on the heater will not help, we can first use a soft towel or a special anti-fog towel to wipe off the fog on the glass. This is the quickest way to do it. Be careful to try to stop the car before wiping.

If you want to defog as soon as possible when driving in winter, then if there is fog on the window, you can turn on the defogging button in the center of the car, so that it can be removed.
