To be honest, how long have these car rumors tricked you?

Recently, the WeChat team's newly launched small program, WeChat Rumor Aide, has been used as a gossip terminator in a circle of friends, and a variety of crazy “great truths” in the circle of friends, making many innocent little whites. At first he had to face the various things in life with a fierce fear, and the arrival of WeChat Rumor appeared to be just like an energetic justice messenger, shattering the big lie that deceived everyone. Today, we also decided to be a rumors rumors of a car circle. Those rumors that convinced us for many years are the time to be finished!

NO.1 high-speed hair float is too light

Until now, many elderly consumers still firmly believe that the heavier the material is, the more stable the car will be at high speeds. Is it really because of the weight of the car that the car is flying at a high speed? It is necessary to know that more and more luxury brands and even super running brands are devoting themselves to reducing the weight of their bodies, and these cars have a very high stability when they are driving at high speeds. This reality has already been given to the rumor. Remember the loud slap!

Then we have to figure out what the stability of the vehicle at high speed depends on. Almost all racing cars and supercars are designed with particular emphasis on aerodynamics. When the vehicle is moving fast, the air flow between the roof and the bottom of the car will be different, resulting in a certain amount of lift, causing the vehicle to be “lifted”. Therefore, it is very easy to cause the car to float, so the manufacturers will use some unique body exterior design to improve the air flow when the vehicle is in motion, so that the car is tightly "pressed" on the ground, such as Weilai NIO EP9, Relying on the adjustable spoiler control system, aerodynamic devices such as full-size chassis diversion slots can provide downforce of up to 24,000N. In theory, when the speed reaches 240km/h, the huge downforce is enough to make it in an inverted posture. Drive on the ceiling.

In addition, the short-stroke suspension is less sensitive to the response of the body to the long-stroke suspension, and the time for the flattering of the body during high-speed travel is shorter, which naturally helps to improve the stability of the vehicle at high speeds. The imaginary position of the steering wheel affects the feeling of correcting the trajectory when driving at high speed, and it also makes us feel that the body seems to be out of control. In the same way, the lower center of gravity is also the nemesis of the car flying at a high speed, which is why the sports car is trying to reduce the height of the chassis.

NO.2 thin car = insecure

The thin skin threat theory has spread far in the automotive world. The biggest focus of this remark is the Japanese car. Isn't the thin car really safe? Can you tell whether a car's safety is good or bad by pressing the "Yang Yang Zhi" twice on the hood? The design of a car body is a very complicated project. Not only should the hard place be strong enough, but the soft place should not be blindly forced. In order to minimize the damage to the occupants during the collision, it is sometimes necessary to sacrifice the car. Many people may not know that the front, rear and side parts of the car are designed as energy absorption zones to be used in The crumple deformation occurs when a certain speed collides, thereby absorbing the large kinetic energy generated during the collision and reducing the speed of the vehicle.

In the frame and the rigidity of A, B, C pillars and welding technology must be hard, the use of high-strength steel can never be smashed, this is the most effective and last safety cage to truly protect the passengers in the car. As for the strength of the hood, know that almost all models are committed to allowing the hood to bend and fold like a dough in the event of a collision, and no designer wants to design the hood of his car at any time. Because the hood with better crash performance during the collision process, the more effective it is to protect the safety of pedestrians, it can also prevent its intrusion into the passenger compartment causing damage to the occupants in the vehicle.

NO.3 neutral gear glide oil

Almost all experienced old drivers will be patted on their chests with the name of a person who came over: "When you are taxiing, you don't want to get ah, save fuel!" However, is it true? The author can say very responsibly: Yes! But that is the past! It must be known that the carburetor is the mainstream oil supply method more than ten or twenty years ago. For a purely mechanically controlled carburetor, no matter which gearbox is located, as long as air enters the air intake, there will be Gasoline is sucked into the combustion to do work, and the fuel injection quantity increases synchronously with the increase of the intake air amount, so that when the vehicle is running at a high speed, even if the throttle is released, the high-speed engine will still be in the intake stroke. The generation of low pressure causes the gasoline to be drawn into the carburetor chamber in large quantities, causing excess fuel consumption. The low engine speed during neutral coasting naturally reduces fuel consumption.

However, in today's society, it is almost impossible to buy a new car with a carburetor. The era of EFI engines has long been fully realized. The engine's ECU can independently control the injectors of each cylinder, with overspeed shutoff and deceleration. The function of cutting off the oil is such that the engine of an incoming call injection engine is in the state of oil cut off when the gear is coasting, and the state of fuel injection is in order to maintain the rotational speed when the neutral is coasting. It is true or false to use the model with the instantaneous fuel consumption display function. Try to know. In addition, subjects have clearly stated in the examination that the ban on coasting has long been foreseen. Naked gliding will cause the engine to lose traction and braking force on the vehicle. It will be very easy for the brakes to decay due to a long time on the brakes to control the vehicle speed. It will cause serious damage to the transmission.

NO.4 trunk water storage for a long time toxic

During the hot summer months, many owners choose to put a box of water in the trunk to prepare for the unexpected, but over time the issue of “poisonous water in the trunk” has surfaced. The reason for this claim is that everyone feels that under the high temperature in the summer, the plastic water bottles stuffy in the trunk will release toxic chemicals, and the mineral water bottles placed under the front windshield will be deformed. Must be toxic!

For this argument, someone experimented with exposing the same group of mineral water to the sun under the windshield of the hot sun, and the other group to “snorkel” in the shade of the room. After one week, the two groups of mineral water were taken out and commissioned. The comprehensive testing center of the China Academy of Inspection and Quarantine carried out comparative tests. The experimental results showed that 18 types of carcinogenic plasticizers such as dioctyl phthalate (DEHP) were not detected in the two bottled water samples.

At present, more than 90% of plastic bottles filled with drinking water on the market are made of organic PET. As long as the temperature is less than 120°C, PET materials are very safe. Although the bottled water in the trunk is not poisonous, when the temperature exceeds 80°C, the plastic water bottle will become soft and the water in the bottle will oxidize, which will inevitably affect the taste. Therefore, although such water is not poisonous, we do not It is recommended to store bottled water in the car for a long time in summer.

NO.5 eggs lick glass, can not open the wiper

A few years ago, the news of the robbery of eggs before the attack on windshields spread like wildfires. As soon as people talked about the egg attacks, the key issue was that after the eggs hit the front windshield they must not immediately spray glass water and turn on the wipers, because Eggs appear white when they encounter water, and the substance blocks the sight rate as high as 92.5%. At the same time, those who stand behind and get off to view due to block sight will be attacked by robbers. . .

(Open the wiper and spray immediately)

Experiments have been conducted on this description. The facts show that when the vehicle is driving at a speed of 20 km/h, the eggs will break apart quickly after being dispersed on the windshield. If we turn on the spray and wiper in time, large areas of eggs will After being cleaned up, there will be no obvious traces on the glass after repeated.

(Open the spray and wiper after waiting for a while)

If the egg breaks on the front windshield and continues driving for two or three minutes before opening the wiper, the egg white part will solidify. Although the cleaning effect of the water spray on the wiper is still OK, the glass will remain clear after drying. Traces affect the line of sight, and this phenomenon can become severe as the egg's residence time increases. From this point of view, the best way to dispose of the “raw egg attack” incident is to immediately open the wiper and spray water to clean it up. The longer the delay, the more serious the consequences.

Conclusion

The rumors themselves are not horrible. The horror is everyone’s gullible beliefs. In fact, the rumors about the daily use of cars are far more than these, and the Carway Channel is willing to be a rumored assistant in the traffic flow of everyone. There are any doubts about the experience in China. Welcome to rumors in the comments section below. We will find the most scientific criteria to help you verify the authenticity of these "experiences."
