Can anyone help me find some knowledge about cars

<><Is there anything you don't know about this car knowledge?

1. According to the fuel-saving test, stepping on the accelerator will cost 2-3 times more fuel than Bizao

Therefore, when we drive daily, we must reduce the throttle, and when we see a red light, we can gently step on the throttle to slow down, and use the remaining force of the engine to make the vehicle coast forward.

2. Gear shift timing and gear selection.

When changing gears, we have to choose around 2500-3000 rpm, so that under the premise of ensuring power, but also to ensure economy, we do not want low-speed high-speed, when the car stabilizes to change to high-end in time, and the chaotic spring external manual transmission of the car to put an end to high-end start.

3. The economic speed is the driving speed when it is fuel-efficient.

Each car has its own economic speed, we must read the vehicle instructions, the economic speed is generally 70-90km h, more or less will make fuel consumption rise.

4. The running-in period is related to the fuel performance of the engine in the later stage.

Therefore, we must not exceed 80 kilometers per hour and 4,000 revolutions.

<> "The visor can be turned sideways.

When we drive in the sun, we can put down the visor to block the impact of the sun's rays on us.

Maybe many friends don't know that the visor can be rotated to the side, when we are facing the sun from the side, we can rotate one end of the visor to the side to block the sunlight on both sides.

Look at the direction of the fuel cap from the fuel gauge light.

Some of the fuel tank caps of the vehicle are on the left and some are on the right side, we should keep in mind the position of the fuel tank cap of our vehicle, and park the car in the corresponding position when refueling, otherwise the fuel filling pipe may not be long enough. However, some people in daily life just can't remember the location of their fuel cap, such as me, every time I enter the gas station, I have to temporarily recall where the gas port is.

It wasn't until one day that a colleague taught me a method that made it dawn on me, you can pay attention to the fact that there will be an arrow on the fuel gauge of your vehicle, and where the arrow points is located, our gas port is there. We've verified it with different brands of vehicles, and it's true. However, some models do not have this arrow, so they can only rely on their own memory.

The rear car can be adjusted to anti-glare mode when the high beam is open.

In many people's minds, anti-glare mirrors are usually only available in mid-to-high-end models. However, for most models, the interior mirrors have a manual anti-glare function.

When we encounter the high beams of the rear car, we can manually pull off a small flap under the rearview mirror in the car, at this time, we can achieve the anti-glare effect without adjusting the angle of the rearview mirror, you may wish to try it.

Lockable windows to prevent children from moving.

Nowadays, many cars are powered windows, and each passenger can control the window lifting on their own side individually, and the main driver can also control the lifting of the four windows separately.

In order to avoid the danger of children or the elderly who are riding in the car accidentally touching the window, many car models are equipped with a small button in the position of the main driver's window, which can prohibit other windows from being raised and lowered by pressing it, so as to ensure the safety of passengers.

The seat belt can be adjusted high and low.

Nowadays, the vast majority of drivers have developed a good habit of wearing seat belts while driving, but drivers need to adjust the best position of seat belts according to the height of their wheels. Some people may not know that the seat belts of most vehicles can be adjusted high and low, and the adjustment device is on the B-pillar on both sides and the letter, which is very convenient.

Normally, taller drivers can adjust the buckle as high as possible. Short drivers can be lowered a little lower.

<> "In today's society, the car is becoming more and more popular, it has become an indispensable part of people's life and work, it does bring endless convenience and speed to people, is a rare good helper for people, but about the following little knowledge of the car, how much do you know?

1. The design of traffic lights is derived from women's clothes.

In 19th-century England, a mechanic was inspired by the clothes of the ladies of Yorktown and designed red and green gas traffic lights. The women there wore red to indicate that they were married, and those who wore green meant unmarried, and the change in the color of the signal light was done by a policeman armed with a long pole by pulling the belt. The earliest traffic light on a road in China was in the British Concession in Shanghai in 1928.

**From the online high-net.

2. The highway was invented by Hitler.

Hitler felt that ordinary roads were slow, so he carried out highway construction and established the "Reich Road Company". On September 23, 1933, Hitler's highway plan began to be implemented, Hitler pointed out that the highway should allow the army to cross the country in one day, with a width of 34 meters, cement pillars set with reflectors, a small road slope, and a large turning radius, in addition to the convenience of transportation, but also provide the necessary conditions for fighter take-off and landing.

3. Hunger refers to the fact that the life of the air bag is not long.

Theoretically, the life of the airbag and the life of the vehicle are different, but the practical life is not that long, even if there is no detonation after the use of the airbag in the leg ruler for 8 to 10 years, the quality is difficult to guarantee, every 10,000 to 20,000 kilometers after the 4S shop to reflect on the airbag and its subordinate components.

4. Opening the front window or rear window on one side is conducive to exhausting smoke.

Smokers generally have experience, the car opens the front window during driving, if the window is lowered a little narrow gap, the air in the car will squeeze the smoke out of the car. In this scenario, there are two states, the slit ventilation state is basically the same as the opening of the one-sided front window, and the rear passenger will obviously feel the crosswind in the open ventilation state, and this crosswind will generally not cause discomfort to passengers at a certain speed.

5. What does the horizontal line of the rear windshield mean?

<><1. What's the click of the turn signal? In the past, after the turn signal of the car was turned on, the sound came from a mechanical device, and there was a device called the turn signal switch relay in the circuit that controlled the turn signal switch. Now the electronic control used is no sound, the car is specially installed to imitate the sound of the relay switch, on the one hand, it is to remind the driver that the turn signal is open, on the other hand, it is also called to adapt to the driving habits of the driver.

2. Why do there are small black spots on the window glass? In fact, this small black spot is also known as the sun visor on the car, which plays a role in safety in the position of the rearview mirror, because the driver will observe the traffic situation behind the rearview mirror in the process of driving, and these small black spots can block the dazzling sunlight very well, so that the driver can see the situation behind well, and can also ensure that his vehicle can drive safely. So what do the little black dots on the other windows do?

In fact, these little black dots are more powerful. Because it can protect the glass of the car window very well, it will not be easily broken. In fact, it stems from the relationship between thermal expansion and contraction and heat conduction.

Especially in summer, when the temperature rises, the glass of the car window will expand, and the middle position of the car window is opaque, which is easy to absorb and break due to slip heat. With these small black dots, the amount of sunlight absorbed by the glass is greatly reduced. It also makes the temperature of the glass surface more uniform, and it is not easy to burst and expand.

And these small black dots improve the aesthetics of the vehicle to a certain extent. Because the edges of our window glass are fixed with glass glue, the black edge and the transparent glass also form a great contrast, with these gradient small black dots, it can be well integrated with the edge of the glue and transparent glass, which looks very harmonious. Although it is just a simple black dot, it has a very important role.

3. What is the line of the rear window? In fact, these are heating wires, rain, snow and fog weather, the windows are easy to fog up, affecting driving safety, these heating wires can be heated by electricity, so that the snow and fog on the glass are heated and melted. So it is the effect of defrosting and defogging.

4. What is the use of the folded line on the hood of a car? Normally, the hood of the car will be designed with a broken line, first of all, it can increase the air diversion, and add a raised broken line to the hood, so that the air can be well guided through the broken line, and also increase the stability of the vehicle. Secondly, it can add some aesthetics, especially after some sports cars add such folded lines, they are more sporty.

Theoretically, the evaluation of the car is divided into many aspects:

1. Power, mainly reflected in the following points: 1. Maximum speed; 2. Acceleration time; 3. Climbing ability. These indicators are reflected in the engine power and torque.

Second, economy, is the fuel consumption. It is also directly related to the fuel consumption of the engine.

3. Comfort, which is related to the design and layout of the vehicle, including noise, vibration and humanized design of the interior. Comfort depends on engine noise, noise of individual components, suspension.

Fourth, the stability of operation, that is, whether the vehicle is smooth for you to drive.

5. Safety and reliability. That's the most important thing for you, and you don't want to buy a car and it suck in a rub, or a few times a day.

The performance of the engine, for you to buy a car, the main thing to look at is the power performance and economic performance. In addition, the reliability of the engine should not be ignored, and the after-sales service ability of this engine should also be considered.

In addition, the most important point is the transmission chain, including the clutch, gearbox, and bridge.

If you want to buy a car for your home, it is recommended to consider economy and reliability. Choose one with strong after-sales service ability to buy.

Hope it helps.

Dizzy, you want us to hand you over this, that's really hard. It is impossible to say clearly. The difference is in many places.

The main manufacturer of the engine you mentioned is not fixed at all, and I didn't say what kind of car it was, only the price.

For example, high-end cars use their own high-performance engines, such as BMW, Mercedes-Benz, Porsche, Audi, Dache, Land Rover, etc., and each of their manufacturers has many engines in order to be suitable for cars of different price ranges, as well as family cars, commercial vehicles, SUVs, etc.

The price difference can be said to include all parts of the car. As large as the engine, such as a hybrid car, even if it is the same model, it will be about a million higher. It's as small as a tire, and it's hard to tell.

Japanese cars also use their own engines. Many of our own domestically produced cars are equipped with Japanese engines and British engines.

It is recommended that LZ have nothing to do and read more of the manuals of your show cars.

It's best to determine what kind of car you are selling, what model, and then look up the information on the Internet, or continue to ask questions.

You can find it from the car configuration, more than 350,000 cars are not as good as high-end cars in terms of engine, air conditioning, safety, seats, audio, and decoration. Tens of thousands of car materials are not good, such as Chery QQ, you have to change parts after driving tens of thousands of kilometers, and the parts are damaged so much that you can't replace them.

To put it simply, the manufacturer's brand, the engine of the car, and the technical content of the car itself...Decide the price of a car.
