Today, a snow has added a chill to Beijing. The slippery road surface and the failure of the car have set up a series of examination questions for the owners, and many car owners have paid the "white paper" on the examination paper of the car skill in winter.
In such weather, some owners can't stop braking on the slippery ice and snow road; some owners can't spray glass water; and some owners can't even open the door after this snow, because the door handle can't be popped out.
This heavy snow has made us see a lot of bad things, and we have realized the lack of experience in winter cars.
Today, we will take stock of the problems encountered in the winter car, as well as the solutions.
Snow and ice driving skills
Driving on snowy roads in winter is the most frightening thing for novice drivers, because the car is often out of control. In North America, driving a Ford Mustang out in winter is despised, not because the car is bad, but because the high-powered rear-drive drives out in the winter, which means not caring about the safety of others.
If you're wondering what the Ford Mustang will do on snow and ice, take a look at a nov. 7 news clip:
It can be seen that the skills of driving in winter should be put aside first, and the most important thing to understand is what kind of car to drive out.
In ice and snow roads, tire adhesion is greatly reduced due to slippery road surfaces, and the driving form of the vehicle greatly affects its driving performance.
Leaving aside the influencing factors of tires, the most suitable for ice and snow roads is definitely a four-wheel drive vehicle. Among them, full-time four-wheel drive is better than timely four-wheel drive. If it is a front-drive and a rear-drive comparison, it is definitely an advantage for the rear-drive car to be inferior to the front-drive car.
On ice and snow roads, four-wheel drive models may be relatively unscrupulous, because all four wheels have power output, and the probability of effective power output by wheel friction with the ground is the greatest. When driving a four-wheel drive vehicle, as long as the speed is controlled, the direction is not rushed and the brakes are sharp;
For front-drive vehicles, the "pulling" on the ice and snow road is mainly a large loss of power, and most front-drive vehicles have a center of gravity in the front half of the body. At this time, as long as the understeer problem caused by the speed is too fast, it will basically not cause oversteering or inability to drive;
But for rear-drive cars, there are many problems. Rear-drive models can be understood as "carts", the rear wheels output power and the front wheels are responsible for steering, if the road surface is slippery, the front wheels steer too large, then the rear wheels are very easy to slip and lose control. Driving rear-drive vehicles need to reduce the throttle opening and steering angle to avoid wheel slippage and oversteering. Especially in the uphill section of the ice and snow road, it is necessary to measure the force, otherwise it is very dangerous to climb halfway down.
Then, after distinguishing the driving characteristics of their own vehicles, all car owners should understand the driving skills of ice and snow roads. In the case of only four seasons of tires, you should start slowly, refuel at a uniform speed, and avoid sharp acceleration and sharp direction.
Nowadays, the vast majority of vehicles are equipped with ABS systems as standard, so in case of emergency, old drivers in the past may be accustomed to fast point brakes, but models with ABS can brake at full strength, allowing ABS to achieve fast point brakes that cannot be reached by human feet.
If you pass through some rutted and deep snow sections, the snow is similar to the sand crossing, that is, "faster than snow". With a safe route and distance, pass through snowy sections as quickly as possible with slightly larger throttle. If it is as slow as crossing the water, then the front and rear drives are likely to fall into the snow and cannot get out of the trap.
Winter car trivia
Suddenly, winter comes overnight, which catches many car owners off guard, and vehicles are prone to encounter many small problems. For the sudden winter of the vehicle problem, can you solve them one by one?
Can glass water be mixed
Glass water is divided into two categories: summer and winter, and its main difference is in its function and freezing point. In summer, glass water is mainly dewormed and decontaminated, while winter glass water is mainly antifreeze and destatic.
The sudden cooling has made many car owners have not had time to change the winter glass water, so that the low temperature to the glass water is frozen. If the glass water is relatively full, it is easy to break the kettle and pipeline because it increases in size after becoming ice.
If you encounter a situation where the glass water is frozen, do not press the water spray switch all the time to avoid burning the motor. You should find a warmer underground parking lot or indoors, and wait for the glass water to melt naturally, and then spray it all out. It should be noted that if it is an SUV or hatchback model, most of the rear windshield also has a glass water outlet, and do not forget to put away the glass water in the rear when emptying the summer glass water.
Some car owners will ask if after winter, the original addition is 0 ° C glass water. If you add -20 °C or -40 °C glass water will not neutralize the freezing point, and different colors of glass water can not be filled together.
In fact, glass water is mainly clean and lubricating, and the general composition is similar, so the occasional mixing is no problem. However, because different manufacturers of different glass water still have differences in composition, it is not guaranteed that it will not react at all, so mixed addition is only an emergency. If possible, it is still necessary to remove all of them and replace them with the same winter glass water.
For the freezing point problem, the glass water mixed with different freezing points can only solve the problem of not freezing ice to a certain extent, but it cannot solve the freezing point problem 100%. The moisture in the glass water in summer can also be frozen, even if the glass water is mixed with -40 ° C, it is not guaranteed that all pipelines will not be frozen, because the glass water is not a heating rod.
How to maintain winter tires
Most of our car tires are filled with air, so the tire pressure will change slightly with the change in temperature. It is necessary to check the tire pressure in winter, but it should not be too high and too low, and the standard value can be.
If the owner of the condition can find a professional auto repair shop to fill the tire with nitrogen, because nitrogen is an inert gas, almost will not change easily according to the change of outdoor temperature, can ensure the stability of the tire pressure. However, nitrogen costs are high and general tire stores may not have one.
In addition to the problem of tire pressure in winter, there are also riders who will care about whether to change snow tires. From the perspective of most cities, if there are sanitation workers sweeping snow, and the snow is not ordinary in winter, there is no need to change snow tires. Even many cities in the northeast do not need snow tires to survive the winter.
If it is an extremely cold area such as Heihe and Hailar, and there is a thick snow accumulation for a long time in winter, it is necessary to have snow tires or nail tires. If a northern city like Beijing has less snow and snow, it is completely unnecessary to change to snow tires to increase driving noise and fuel consumption.
It is worth noting that the winter tire itself is affected by low temperatures and slippery road surfaces, resulting in poor rubber adhesion, so the pattern and pattern depth of the tire are extremely important. In winter, try to choose four season tires with better grip and better drainage, if the surface of the tire is found to be seriously worn, it is recommended to replace it as soon as possible before winter to ensure the safety of winter driving.
What to do about frost and foggy glass
After the weather is suddenly cold, the windshield of many vehicles will freeze outside. There are two ways to deal with frost, one is to use a rubber shovel that does not harm the surface of the glass for eradication, and the other is to melt it through the warm wind blown glass inside the car.
However, if there is more frost, it is recommended to take the first method, because the vehicle takes a long time to go from cold to completely hot in winter close to idle. After removing most of the snow outside the glass, check whether the wiper is frozen, if the spray glass water removes ice and snow, you should tap the switch to observe whether the water spray is normal and working, so as not to damage the motor.
If you want to try to avoid frost on the windshield from being parked outdoors at a low temperature for a long time, after stopping the previous night, open all the doors, let the temperature inside the car as close as possible to the outdoor temperature, and then lock the car. At the same time, the wiper is erected. After being parked outdoors, there is hardly too much frost on the windows the next day, and the wiper will not freeze to death on the glass.
For the winter driving, it is easy to fog up, because the outdoor temperature is low, and the hot air exhaled by the passengers in the car and the hot air of the warm air will cause fog to form inside. In this regard, the riders can adjust the warm air to a large air volume and continue to blow the windshield. If the fog increases in the early stage, it does not matter, wait for the warm wind to continue to blow the windshield, after a period of time you can restore the cleaning field of vision, and the fog will disappear.
Write at the end
With the sudden drop in temperature, car owners have begun to use cars in winter. For ice and snow roads, although wet and slippery increase the difficulty of driving, do not underestimate the tire developers and vehicle development engineers, as long as you maintain safe speed and correct driving skills, safety will definitely be greater than danger.
Because of the decrease in temperature, it is recommended that car owners increase their inspection and attention to the vehicle. Antifreeze, glass water, motor oil, tires, and batteries are all places to be checked frequently. These may determine whether your car can operate properly, and for the safety of driving on the road, it is more dependent on driving experience.
If you're experienced enough, the Scandinavian cornering that the Nordic people make good use of can also be tried.
