You have been fooled by the old driver again!Do you know a few of these car common sense misunderstandings

With the rapid development of society and economy, many families have begun to own private cars. Although there are more and more car owners, how many car owners know how to choose and use cars? Most car owners are just like people. When others say it is right, they will feel that it is correct. In fact, they don't know that many of them have misled themselves and others.

The following big guys will list some misunderstandings in car selection and use. Car owners should remember, don't be misled by these misunderstandings.

Wash the car to clean the air conditioner

It’s okay to wash the car, but it must be maintainedCar Air ConditionerDry outside, ifcarIf the air conditioner gets wet, it will affect the life of the car air conditioner. So pay attention when washing the car, don't get the outside of the air conditioner wet.

Car waxing should draw a circle

This depends on the specific situation. Too much research is not helpful, and the time is short.brakeThat's fine. For a long time, you can put the handbrake in neutral and let go. It's not worth doing this action in a period of time in order to save those two drops of oil.

Glide in neutral to save fuel

In fact, the electronic fuel injection engine technology on many models has been able to prevent the vehicle from injecting fuel at all in the state of coasting with gear, and if you coast the engine in neutral gear, it will be regarded as an "idling state" and therefore spray extra fuel. It is not simple at all to save fuel, and it also seriously affects driving safety.

Save fuel without turning on the air conditioner

First of all, long-term non-use of the air conditioner will causecompressorDamage. In fact, if you open the window without turning on the air conditioner in order to save fuel on the highway, it will increase the wind resistance, and it may be more fuel-intensive.

Manual gear is more fuel-efficient than automatic gear

In the past, there were fewer automatic gears. This makes sense. The current automatic models have increased gears and improved shifting procedures. The fuel-saving effect is no worse than that of manual gears.

The more configuration the better

Some tasteless functions, such as headlight cleaning, luggage racks, etc., are estimated to be used less than once in three years. What use is it for?

Joint venture imports must be better than domestic cars

Chongyang and foreigners, now many domestically-produced cars are not lost in joint venture imports in any aspect, and it is a waste of face.

"Deposit" and "Deposit" are the same

The biggest difference between the two is that the "deposit" has a guaranty effect, while the "deposit" has no guaranty effect. If you sign a "deposit" at a 4S store, and you regret later, the deposit you paid before will also be "washed"; if you sign a "deposit" at a 4S store, if you sign a "deposit" later, the penalty will be deducted In addition, part or all of the deposit can be recovered.

Water tankAdd water to cool down when overheated

Some drivers think that adding water when the water tank is overheated will help cool down. In fact, this will cause the cylinder head to crack due to sudden cold. It should be to stop the engine to keep the temperature, wait for the cooling water temperature of the water tank to decrease, then turn off the flame, and then slowly add the cooling water.

Turbocharged engines are better than naturally aspirated engines

Turbocharged engines only reach a certainRotating speedWhen the turbocharger is not working, the turbocharger will be involved in the work, so when the turbocharger is not working, there will be a small horse-drawn cart situation. At this time, the turbocharged engine is more "flesh" than the naturally aspirated engine. When the air conditioner is turned on while driving, the fuel consumption will be higher than that of a naturally aspirated engine. Moreover, the maintenance cost of the turbocharged engine is higher than that of the naturally aspirated engine in terms of maintenance cost in the later period.

A car without an anti-collision beam is not safe

Many people think that the anti-collision beam is the most important configuration to protect the safety of the occupants in the car. In fact, this is not correct. What really determines the safety of the occupants in the car is the body structure design and the amount of high-strength steel in key parts of the body. Only play a role in assisting energy absorption.

Thicker wagons will be safer

The thickness of the car skin will affect the damage of small collisions, which in turn affects the maintenance cost, but the most important thing for protecting the safety of passengers is the strength of the steel frame, whether it can keep the car body intact after a collision.

The heavier the car, the safer it is

One of the two cars of the same level is light and the other is heavy. It may be because the latter's lightweight design level is not enough, or the strength of the steel frame is not good enough to be made stronger, which often does not mean that the latter has the best safety.

Independently suspended cars must be better than non-independently suspended cars

As far as the sense of control is concerned, it is true, but now many non-independent rear suspension models have no less than the fully independent suspension models in tuning, and there is more spacious rear space.
