According to the "Tianjin Meteorology" news.
Currently, our city is on a blue alert for a cold waveCoupled with the blessing of the wind, the cold is cold!
Tomorrow morning's lowest temperature in the city will be onlyThe minimum temperature in the northern region will dropFurthermore, the maximum temperature during the day tomorrow is onlyUp and down, if you can not go out tomorrow, you should not go out, and you must also be "fully armed" to take measures to protect yourself from the cold and keep warm.
The temperature plummets, and the temperature difference is large.
It is very easy to cause the windows to fog up!
It brings safety hazards to driving.
Open window convection – fuel-efficient but cold
When the fog in the car is not largeIt is possible to open a gap in the windows on both sidesLet the air inside and outside the car form a convection, reduce the temperature difference, and the fog will slowly disappear. The principle of this method is the same as turning on the air conditioner for cold air, but it does not increase fuel consumption.
Although it is convenient and quick to open windows for convection, it is not suitable for rainy and snowy days and heavy fog.
Air conditioningDefogging – Fuel-intensive but fast
For most car owners, the use of air conditioning system defogging is the most common, at present, basically all cars on the market have air conditioning outlets under the front windshield, just select the air conditioning to the corresponding gear.
Cold air defoggingIn winter, the temperature difference between the inside and outside of the car is too large, and it is cold on the outside and warm on the inside, so it causes the windows to fog up. Turn on the AC refrigeration switch in the carLet the cold air blow through the front windshield, the fog will soon disappear.
But one of the biggest drawbacks of this method is that when it's cold, the people in the car feel very cold, and after the cold air is turned off, the fog may reappear.
Warm air defoggingUse warm air to defog at the same timeOpen some gaps in the front side windows, and after a while the fog will be dried by the warm air, which is very effective. Use warm air to remove fog, it is recommended that you use it before driving on the road.
Adjust the side window air vents – drive safely
Sometimes the side windows can also fog up, affecting the driver's view of the rearview mirrors on both sides of the car. At this time, we can adjust the air outlet by the side window on the basis of air conditioning defoggingDo not allow it to blow directly onto the glass of the side windows, which can generally be solved.
Heater is the most basic and effective heating facility in a car, which uses the engine's circulating cooling system to generate heat, which is transmitted to the cab through the blower, which belongs to heat reuseTherefore, the power consumption of the heater is much lower than that of the air conditioner, and the fuel consumption is negligible
If you feel that it costs oil to turn on the heater.
It is most likely caused by improper operation.
The right thing to do, hurry up and get it!
Do not turn on the heater immediately after the car starts
Turning on the heater as soon as the car starts will cause the engine to be overloaded, which will definitely consume fuel, so everyone will generally mistake it for the heater. The right thing to do is,After the car starts, wait 3-5 minutesWhen the water temperature rises, turn on the heater.
Do not turn on the A C button
The A c button is the air conditioner, and pressing it means that the compressor used for cooling has started to work, which will increase fuel consumption. If you want to turn on the heater, you don't need to turn on this button.
The loop mode is set to Inner loop
If the air conditioner is set to internal circulation, the temperature inside the car will rise rapidly. When you feel that the car is warm, you can switch to external circulation, which will help the air circulation in the car. 
A temperature adjustment of 23 is most suitable.
Pay attention to adjusting the wind direction of the air outlet.
Do not face the face, it can easily lead to fatigue.
When the vehicle is idling, due to the incomplete combustion of gasoline, a large amount of harmful gases such as carbon monoxide will be generated, which will enter the vehicle with air circulation. In addition, people will consume a lot of oxygen in the car and exhale carbon dioxide, which is easy to be poisoned.
When the heater is turned on in the car for a long time
Leave gaps in the windows
If you feel dizzy and weak.
Get out of the car in time and get some fresh air.
When you usually drive, every once in a while.
It is necessary to switch between internal and external circulation or open windows for ventilation.
