Some commonly used car knowledge Car trivia

The rearview mirror in the car has manual anti-glare function. When the vehicle behind you turns on the high beam on the road, you can manually pull under the rearview mirror of the car.A small flip plate, at this time, without adjusting the angle of the rearview mirror, can achieve the anti-glare effect.

Car structure: A car usually consists of four parts: engine, gearbox, driving axle and body. Among them, the engine is the heart of the car and is mainly used to drive the vehicle. The gearbox is used to control the wheel speed and the torque of the drive shaft. The running bridge is used to transmit power to the wheels and provide suspension and braking systems.

Practical knowledge of automobiles The wear of the clutch disc and clutch pressure plate, the spark plug has been used for too long, and the phenomenon of increased fuel consumption will also occur, so it should also be replaced regularly. Misconceptions of driving knowledge: empty gear can save fuel. In the early days, empty gear can save fuel, but the electric injection car we use now is not.

Do you know the following car trivia?The airbag needs to be overhauled in about 8-10 years.

Check the car battery. The battery water must be replenished immediately to adjust the relative density of the battery electrolyte. And check the power storage. If the battery is insufficient, remove the battery and charge it. Check the tire pressure.

When driving an ordinary sedan with a speed of 20km/h, it will produce about 23,000J of energy. The total kinetic energy of the muzzle fired at the same time as 15 M4 carbines is almost the same. In fact, the impact force is quite high for pedestrians, which shows that safe driving The importance of.

The car trivia that must be understood is all dry goods

1. Why can it take one night to pick up the car after replacing the windshield?The front and rear windshields are fixed to the car body by professional glass glue, and the glass glue generally has a completely dry cycle of one to three days depending on different qualities and seasonal factors. If the glue is not dry enough, it will easily make the windshield fly out of the car.

2. What are the reasons for the white smoke, black smoke and blue smoke in the car? White smoke: mainly water vapor. In winter, the cold car is particularly obvious, and it is normal to disappear after a short period of time. However, if white smoke is sprayed for a long time, and more water is dripping out of the exhaust pipe, it is necessary to consider whether the car has entered water or the engine punching machine. Blue smoke: It is likely to burn engine oil.

3. The car trivia that you must know are all dry goods. Let's see what you know? Look at the direction of the fuel tank 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. We should keep in mind thatThe position of the fuel tank cap of your vehicle, park the car in the corresponding position when refueling, otherwise the refueling tube may not be long enough.

4. These 6 pieces of knowledge must be understood! For many car knowledge, how to protect their cars has become a big problem in front of them. Because they don't know about cars, they have to rely on 4S stores no matter what problems occur, which will cost a lot of money.

5. This small metal block is called a balance block, also known as a tire balance block. It is a counterweight part installed on the wheel of the vehicle. The function of the balance block is to keep the wheel balanced under high-speed rotation. 1 What are non-load-bearing body and load-bearing body? Non-load-bearing: Cars with non-load-bearing bodies have rigid frames, also known as chassis beams.

6. The car knowledge that novice car owners must master is all "dry goods" from the experience of veteran drivers!It is very important for novice drivers to learn to look at the dashboard when driving, and they should often see the pointer on the dashboard. If they see a red light on the dashboard, turn off the engine and stop for inspection as soon as possible. Be sure to pull the handbrake when parking.

1. Anti-glare rearview mirrors are not only equipped in middle and high-end models, but for most models, in-car The rearview mirror has manual anti-glare function.

2. Car structure: A car usually consists of four parts: engine, gearbox, axle and body. Among them, the engine is the heart of the car and is mainly used to drive the vehicle. The gearbox is used to control the wheel speed and the torque of the drive shaft. The running bridge is used to transmit power to the wheels and provide suspension and braking systems.

3. Light refueling, light braking, early braking. Braking suddenly, starting suddenly, and stepping on the accelerator while driving are all fuel-saving taboos. The fuel-saving test shows that stepping on the accelerator costs 2 to 3 times more fuel than driving at medium speed. Therefore, under the premise of ensuring the normal operation of the car, the throttle amplitude should be appropriately reduced.

4. This article integrates various materials and introduces the following car cooling knowledge. You can see how many you know. Identify the side of the fuel tank cover from the instrumentThe direction of the fuel tank cap of different cars is also different. Sometimes when refueling, you will forget whether the fuel tank cap of the car is on the left or on the right.

5. The car trivia that you must know are all dry goods. Let's see what you know? Look at the direction of the fuel tank cap from the fuel gauge light. The fuel tank cap of the vehicle is some on the left and some is on the right. 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 refueling pipe may not be long enough.

6, 80km/h cruising, the fuel consumption used to overcome wind resistance should reach 60%; if the speed can be driven to 200km/h when driving, the air resistance accounts for 85% of all resistance of the car. This is an approximate value, and different models are also very different, so when buying a car, don't look down on the exterior design.

The common sense of cars is very practical

Misconceptions of driving knowledge: empty gear can save fuel. In the early days, empty gear can save fuel, but the electric injection car we use now is not.

3. After the lubricating oil is applied, the self-locking coefficient between the two becomes smaller, resulting in a decrease in the self-locking performance.When the car is driving at high speed, the bolts and nuts are easy to loosen or even fall off, causing driving accidents with unimaginable consequences. When washing the car, you need to pay attention not to rinse the interior of the car body with water.

4. Check the car battery. The battery water must be replenished immediately to adjust the relative density of the battery electrolyte. And check the power storage. If the battery is insufficient, remove the battery and charge it. Check the tire pressure.

5. Generally, our cars have manual anti-glare rearview mirrors and automatic anti-glare rearview mirrors. Let's see if your car is manual or automatic.

6. You drive skillfully to and from work every day. And the car configuration is very skillful, and some people can even blurt out a car brand and the model and displacement of each car. But cars are still relatively complex machinery, and the most difficult thing is electronic equipment.First, distinguish the direction of the fuel tank cap from the dashboard.
