Winter driving, basically use the warm air, because the warm air compared to the summer air conditioning, the oil is still very little. Because it does not require the compressor to work, it uses the heat generated by the engine itself. However, the use of warm air must also be correct, otherwise it will not only not warm, but also increase the burden of the engine, or spend a lot of oil. Just master the following 5 points, easy use of warm air.
1. Start at the right time
Because the warm air uses the heat of the vehicle itself, it is precisely the heat of the antifreeze. When the fire has just started, the water temperature has not risen, so do not open the warm air at this time. Because even if the warm wind is opened, the cool wind is blown out, and the car will feel colder. At this time, open the warm air, because there has been wind blowing through the warm air tank, which is equivalent to cooling the antifreeze. To know that the heat dissipation intensity is very large, in the summer even if the cooling fan is broken resulting in high water temperature, opening the warm air can also make the water temperature return to normal, enough to show that the heat dissipation is large. Because it has been cooling, it will greatly increase the time to warm the car, and the water temperature can not reach the normal 90 degrees for a long time, and the engine has been in the cool car stage.
This will not only increase engine wear, but also increase fuel consumption. Because when the car is cool, the amount of fuel injection will increase, the purpose is to speed up the speed of warming the car. As a result, a large amount of gasoline will not burn completely, resulting in an increased rate of carbon deposition. Therefore, opening the warm air too early has a great impact on the vehicle. The best time to open the warm air is to open after the water temperature reaches normal, so that there is no impact on the vehicle. And most people don’t wait that long, it’s probably too cold in the car. Therefore, it is recommended to open it at the earliest after the water temperature meter starts to move, and to open it when the temperature is 50 or 60 degrees. After this is opened, there will be warm air immediately, and the impact on the engine is not too great.
2. Wind conditioning is important
Whether it is air conditioning or warm air, whether it is in the car or at home, in fact, there is an optimal wind direction. When the warm air is on, the wind should blow downward, so that the whole car can be warm. Because hot air is lighter, it floats up and eventually collects on top. When the wind blows down, the air under the vehicle is hot, and then gradually floats above the vehicle, so that the entire carriage is warm from foot to head. If you blow directly from the side up, then the hot air will gather directly above the vehicle, which will lead to the head and upper body of the passenger in the car are very warm, but the legs and feet are still very cold, especially the feet, at the bottom, the floor is also cold, will feel colder, also very uncomfortable. Therefore, the driver and co-pilot can adjust the direction of the wind to blow the foot while blowing backward and down, at least the front passenger is warm from head to toe.
3. Turn on the AC switch when appropriate
Open the warm air in winter, only when it is necessary to remove the fog, if it is not necessary to remove the fog, it needs to be closed in time, do not keep it open. If it can not be turned off, pay attention to the wind direction, press a key to remove fog, or manual air conditioning wind adjustment to the glass blowing, some car air conditioning is automatically opened by default, and can not be turned off. So before turning off AC, adjust the wind direction and don’t blow the glass all the time. When the weather is dry, although the temperature difference between the inside and outside of the car is very large, the car will not fog, if the AC is always open, it will waste fuel virtually, resulting in increased fuel consumption.
4. Warm air temperature
The warm air temperature is also exquisite, generally adjusted to about 24 degrees, this temperature is very comfortable, will not cause additional waste of energy. Manual air conditioning does not have a temperature display, you can adjust according to your own feelings, as long as you feel comfortable. Do not adjust too hot, if the temperature is high for a long time driving, easy to accelerate fatigue, the original four hours to feel sleepy, now two hours to drive sleepy, is not conducive to driving safety.
5. Maintenance of warm air system
The heating system also needs maintenance, in fact, the most important thing is to replace the air conditioning filter. If the air conditioning filter is dirty, it will affect the air volume, although the air volume is very large, the temperature is also very high, but it is not warm in the car. This is a high probability that the air conditioning filter element is blocked, and it needs to be checked and replaced. In addition, it is necessary to pay attention to the lack of antifreeze, the lack of antifreeze, the antifreeze entering the warm air tank will be reduced, which will lead to the warm air is not hot.
