Do you want a hot car in winter? Does it matter if the car is not hot?

The weather is getting colder and colder, and the topic of whether to warm the car is asked again. Some friends have heard that not heating the car is bad for the car, and some friends have heard that there is no need to heat the car. This article introduces, do you need a hot car in winter? Does it affect the car?

Therefore, Xiao Mu specially consulted some materials and came to the conclusion that he needed a "hot" car. I put the word "hot" in double quotation marks, which is not a place for rumors. Wait a few minutes before driving. But driving at a low speed for a few minutes after starting, and this driving process is a hot car.

How did the topic of>& gt hot cars come out?

The early carburetor was used to atomize gasoline, so that the car could run normally. If the external environment temperature is low, the vehicle can't pass through the overheated vehicle, and the carburetor can't atomize the gasoline well, resulting in the vehicle being unusable. But now, the carburetor has long been eliminated.

The advice of many "experts" in the automobile circle is that the weather is cold or the car has been useless for a long time. When starting the car, it's best to warm up for a few minutes before going on the road. The topic of car fever has never stopped, with the spread of word of mouth and the advocacy of some car enthusiasts.

& gt& gt An incorrect hot car is not good.

Now the automobile technology has developed very well, and the original floor heating car is a mistake. It not only consumes gasoline, but also produces carbon deposit. If gasoline does not burn completely at idle speed for a long time, it will also emit a lot of carbon monoxide, nitrogen oxides and PM particles to pollute the environment.

Mercedes-Benz's vehicle manual says: "Don't idle the car in the same place, you should start it immediately. But before the normal working temperature, avoid high-speed or high-speed driving. " BMW's vehicle manual says, "Don't warm up the engine when the vehicle is stationary. It is best to start it immediately and drive at medium engine speed. This will enable the cold engine to reach the working temperature as soon as possible. "

& gt& gt How to warm the car?

For friends in most areas, it takes 5~ 10 seconds after the vehicle starts, and it can be started after the idle speed is stable, and it can be recovered after driving at a low speed for 2~3 minutes.

For friends in the extremely cold northern region, you can take a few minutes off as appropriate. Because the ambient temperature is too low, it not only affects the work of the engine, but also has a great impact on the gearbox. For example, the oil in the gearbox becomes viscous at extremely low temperature, which makes it difficult to shift gears. For cars with gearbox cold protection function, they will also be limited to low gear when the ambient temperature is too low.

Does it matter if the>& gt car is not hot?

Yes, but the impact is not as great as we thought. Reasonable hot car is to improve the oil temperature of the engine to reach the normal working temperature and reduce the wear and tear of the engine, which is indeed beneficial.

But it is no problem to drive away without heating the car. Don't worry about insufficient oil lubrication. About 10 seconds after the vehicle starts, the oil is pressed to the surfaces of various parts of the engine. In fact, there is no need to wait at this time. After you start the vehicle, fasten your seat belt, look in the mirror or return to WeChat. The oil has been filled.

Even if it is not stable at constant speed after starting, you can go directly. The time from the initial high speed to the stable low speed is actually the heating of the catalyst.

What is the purpose of heating the catalytic converter? In fact, this is to reduce emissions. What do you mean? To put it bluntly, going directly without waiting for the speed only increases emissions and has no effect on the car.

& gt& gt cars are not that expensive and do not need to be supplied.

On the whole, the car is not so fragile. Even if there is no reasonable hot car, there is no big problem in daily use. For example, if you wash a wok at home, you can wash it with a soft rag, but it is no problem to wash it with steel balls. The wear was slightly larger, but the pot was finally scrapped, which had little to do with whether it was washed with a rag.

Hot car is a constant topic, and it is often controversial. From the point of view of worrying about car wear, it is beneficial to drive at a low speed for two minutes after starting. But that doesn't mean you have to do it. From a psychological point of view, it is also to drive more comfortably. Of course, whatever you do, just be happy.

Friends who want to know more about car use may wish to pay attention to me. I will share a small dry car with you every day to keep you away from the trouble of using the car.
