How does the car start in an area of tens of degrees below zero?

If the car is in good condition, start the same as usual, do not refuel when starting, warm up for two or three minutes after starting, and start after the idle speed drops to a normal value. I was in the alpine region, and the temperature at night was close to minus 30 degrees.

Use antifreeze, and the oil should be used for low temperature, and it is best to take certain measures to keep warm.

Install iron chains on tires to prevent tires from slipping.

Douse the gearbox, engine, with hot water, it is easier to start.

As usual, it is advisable to use pure synthetic motor oil in cold regions.

When the temperature is generally in the range of -10 to -15, it is difficult to start the car cold. When the temperature drops below -40, it will not start at all without warm-up.

In winter, as the temperature drops, the viscosity of the oil increases, making it difficult for the oil to flow, which increases the resistance of the engine. If starting is difficult, check whether the oil label is used.

Wrong. The oil label consists of two parts: grading and viscosity specification.

When the weather is minus 20 degrees, the car can be started, the car should pay attention to before the ignition, spend 10-15 minutes to let the engine generate heat, turn on the ignition switch to let the electronic control system in the car automatically complete the self-test, so as to ensure that the car's fuel supply is sufficient, and then press the clutch pedal, use the starting gear to start the vehicle. Wait for the parts of the whole car to reach a certain temperature before starting to drive. Generally, the temperature is in the range of minus 10 degrees to minus 20 degrees, which is a threshold for car ignition, but when the temperature is below minus 25 degrees, there is a certain difficulty in starting the car.

Low temperature and cold weather will cause certain wear and tear on the engine of the car, and at the same time, starting the car in this environment will also have an impact on the main components of the car, such as the decline in braking performance, and the windshield of the car is easy to freeze. In the weather of minus 20 degrees, if you want to start the car normally, first of all, the coolant of the car cannot be replaced with water, secondly, the oil viscosity of the engine oil should not be too high, and at the same time, the cold start current of the battery should be large, which will reduce the wear and tear of the car in cold weather.

1.The correct way to start is to start again after the interval of 20 seconds after the first start does not ignite, and slowly warm up within a few minutes after starting, and do not rush to speed up the gear. If the car has not been ignited many times, you can also take the method of finding someone to help push the cart to start, this method is that in the case of the battery has electricity, you can test whether the car has electricity by pressing the horn, and you can use this method to start the car when the horn sounds.

2.The temperature in winter is low, basically below zero, whether it is a mobile phone or a tablet and other electronic products will consume more power, car batteries are no exception, in this case of increased power consumption, if the start is not done properly, the battery will be fed, resulting in the car can not start. Many people often make such mistakes when starting the car, when the car does not catch fire, it will start continuously because of the hurry, which is very easy to damage the battery.

3.In winter, as long as you pay attention not to start the car continuously, there is no problem, and you should also pay attention to electrical appliances such as air conditioners and radios, which will also cause power loss due to improper use.

There is no need to do anything, the battery is large enough, on the line, more than 30 degrees of gasoline internal combustion engine only involves a starting failure, it is possible that it is just possible to need some auxiliary methods,

It can be started under normal circumstances, pay attention to the minimum temperature at which the oil and antifreeze are used.

Difficult to start the engine When the temperature is generally in the range of -10 to -15, it is difficult to start the car cold. When the temperature drops below -40, it will not start at all without warm-up.

The influence of low temperature on the wear of automobile engine assembly When the vehicle is used in a low temperature environment, the wear of each major assembly will increase accordingly. decreased braking performance; The windshield is prone to frosting, etc.; The engine is prone to freezing and cracking; The battery is prone to freezing and damage.

Normally, it can be started.

Many northern car owners park their cars outdoors, and theoretically they can put their cars outside, but if their cars are filled with antifreeze and glass water, then as long as the outdoor temperature does not exceed the temperature value of antifreeze, you can put your car outdoors. In general, antifreeze can withstand temperatures as low as -45 degrees, depending on the value of the antifreeze.

In general, when the temperature is between -10 and -15, it will be difficult for the car to start cold. But the car can be started at -50 degrees. When the temperature drops below -50 degrees, the car must be warmed up to start, and it cannot be started without it.

So, when it's minus 50 degrees, be sure to warm up before driving. In addition, pay more attention to the maintenance of the car in the low temperature environment.

The tips for starting a vehicle at low temperatures in winter are as follows:

1. In early winter, we can wax the body to avoid damage to the body paint in rainy and snowy weather. Add high-quality winter special oil, antifreeze, antifreeze glass water, etc. to the car to ensure the normal operation of the car.

2. The temperature is too low in winter, and the battery capacity of the car decreases rapidly, so when using the car in winter, we should pay more attention to the battery capacity and replenish it in time. Avoid situations where the car won't start.

3. We can change the car to winter anti-skid tires to ensure driving safety. Also, when parking your car, try to stay away from trees and billboards, and don't go near low-lying waters to prevent your car from freezing.

If the vehicle is only parked during the day, it is best to choose a sunny place; If the vehicle is outside overnight, it is almost inevitable that the doors will freeze at low temperatures. Therefore, before driving the next day, it is best to prepare a de-icing shovel and a bottle of warm water, once the door is frozen, you can pour warm water on the frozen car door, and immediately dry the door to avoid freezing again.

In addition, the wipers also need attention. Hold the wipers up after parking to prevent the wipers and windshield from freezing. Use a de-icing shovel to remove ice from your windshield before driving to avoid burdening the wipers.

For more information on how to stand up with the wipers, please click on the link to the article "How to stand up with the wipers". Finally, I would like to remind all car owners. In order to make your car survive the winter, it is best to carry out comprehensive maintenance of the vehicle in advance, including antifreeze, glass water, batteries, oil, tires, etc.

Other parts, if there is enough time, it is better to replace them.

Cars can be placed outdoors above minus 50 degrees. The car can be started at minus 50 degrees, but it needs to be warmed up for a certain period of time before it can be started.

The car is about minus 20 degrees, so it can be placed outdoors, and it should not be able to start at about minus 50 degrees.

It can be placed outdoors between -15 and 20 degrees Celsius. At minus 50 degrees, the car won't start at all.

Now the car technology has improved, minus 30 degrees as normal use, as long as your own car can be lit, preheat for about 5 minutes and you can go, generally the vehicle water temperature is at least 40 degrees Celsius or more before starting to drive. Now the minus 30 degree car is basically starting directly, no problem. The big car caught fire after a while of preheating, and the diesel car also had an automatic heating system.

Generally, there is a garage with heating at home, so there is no big problem, even if you don't put the garage, there is no problem to put it outside for a day. It's just that many people don't drive in winter, because of how to drive a meter deep snow, as long as the car is in good condition, the battery is good, and the 5w engine oil is used, the clutch must be stepped on when starting, and there is no problem at minus 30 degrees.

The key is also to look at the battery, and the transmission oil is also very important.

Engine oil temperature binning: 0w -35 degrees; 5w -30 degrees; 10W -25 degrees, choose the right one, and the number of diesel is the minimum use temperature, the general diesel car has a heating device, the key is turned on when used in winter, and the dashboard has an indicator light that will light up after heating, and then immediately rotate the key to start.

To put it bluntly, people in the cold areas of the Northeast do not drive new cars, and they do not use any special methods to ignite the fire, and the cars will not fail to ignite if they are more than ten degrees below zero or more than twenty degrees below zero, but the sound when starting is more ugly.

People in the Northeast, normal change of antifreeze oil on the line, the temperature below zero oil is not frozen, so it can start normally, the water tank is added all year round is antifreeze, as long as there is no shortage, do not care about it, generally one or two can be fired, in this case, it is best to wait for a while before starting the car, which is good for the engine.

At present, the limit requirement for the car is: under the low temperature of minus 40 degrees, it can be successfully ignited at one time. In Heihe, China, there is a modern vehicle cryogenic test site. Many new models of vehicles will make a special trip there to do low-temperature tests before they are officially put on the market.

To put it bluntly, it is a good battery, sufficient electricity, winter engine oil, and high-quality antifreeze. are normal starts, conditional can warm the stock car, diesel cars are sometimes not good to start, add 1-2 more batteries on it, see some of the batteries written on the Northeast special.

In addition, an electric heater can be connected to the antifreeze line with a circulating pump. If it really doesn't work, there is a kind of 'electric blanket', plug in 220 electricity half an hour in advance, preheat it up, and it's OK to light it.

Need a hot car.

When driving in severe cold weather, the engine is most affected, because the oil in the engine will lose its activity and become viscous when the temperature is low, and it is difficult for the oil in this state to play a lubricating role.

If you start directly and leave, the engine will not be lubricated by oil, which will affect the normal use of the engine. In severe cold weather, if the car is not hot, it will cause the engine to pull the cylinder, so it is very necessary to drive a hot car in winter.

Starting the car at more than minus 20 degrees, this must need to be hot! And you need to heat up the car in situ! If the minimum ambient temperature is only about 0 degrees, it is actually completely unnecessary to heat the car in situ, and many car user manuals also have requirements:

As soon as the car starts, it should drive at a low speed. Generally speaking, when it is more than minus 20 degrees, it is recommended to start the car and idle it for 1-2 minutes, and use this time to clear the snow and smoke a cigarette. Raise the engine temperature slightly and the oil to the operating temperature.

Then drive at a low speed, and wait until the water temperature light goes out or the water temperature gauge needle moves slightly, indicating that the water temperature has reached 40, and then you can drive normally. ‍‍

Hot car is still very necessary, of course, I don't mean that in any case you need to heat the car, and you don't need to warm up the car for a long time, according to the problem, minus 20 degrees is definitely the need to heat the car and then go, if it is normal temperature weather, then you can idle in situ for about 30s, and then drive normally for a distance, and then hit the throttle on the throttle, then it's not a thing. ‍‍

In the past, older vehicles need to heat up the car, this is a thing that everyone knows, some old drivers need to heat up the car for several minutes, and then later, as the vehicle manufacturing technology is more and more advanced, there is a new saying, the current vehicle no longer needs to heat the car, directly start the vehicle and step on the accelerator to go. But in fact, today's vehicles still need to be hot, especially in extremely low temperature environments, and hot cars are very necessary. Because although as long as you choose the engine oil with a high antifreeze index, you can start the vehicle normally in a low temperature environment, but the low temperature will make the oil thicker, we still need to wait for the oil to reach the surface of each part of the engine and return to a relatively smooth flow state before driving normally. ‍‍

Yes, the main reason is that the oil in the engine can be fully lubricated, and the oil in the engine flows back into the oil pan at the bottom of the engine after the car is parked for a long time.

The car was put overnight, the oil existed in the oil pan, the concentration of cold engine oil increased, the fluency in the pipeline was poor when the cold car was working, and the gas connecting rod and cylinder wall on the high position of the engine could not be lubricated immediately. In order to make the engine have a good working temperature, it is necessary to warm up the car every morning when we drive (whether you are in the north or in the south). There is no need for textbook-style details, it is simple and easy to understand, as long as it is helpful to riders.

Finally, this rider mentioned the question of whether it is necessary to warm up at minus 20 degrees, and it is even more necessary to preheat the car in the north, the car is its own, don't fool the pseudo-experts. ‍‍

You definitely need to warm up the car, if it is really minus 20 degrees, then you must warm up the car to go. Many people should have heard that some car owners need to warm up the car for a few minutes before driving, whether it is in the hot weather of more than minus 10 degrees or more than 20 degrees, you can often see the owner start the car, sit quietly in the car and wait for a few minutes. In the past, when carburetors were used, the carburetor used the kinetic energy of the inhaled air stream to atomize the gasoline, and then injected the mixed compressed gasoline and air into the combustion chamber.

Therefore, when the temperature is very low in winter, the oxygen content is relatively low, and the carburetor cannot be injected normally. But don't think that now that car technology has developed rapidly, cars don't need to be hot, when the temperature is low, you can try to start the accelerator directly and go, you will find that the engine sounds like a tractor roaring. And if you don't start the car hot, then the shift is not very difficult, especially in the case of low temperatures, the jerky shift of the cold car is because the gear oil flows to the lower half of the gearbox in the cold car state, and the transmission gear is not fully lubricated. ‍‍
