Why are some car fuel tanks on the left and some on the right?

First of all, you should know that China's vehicles drive on the right side of the road, so usually the fuel tank port of domestic cars is on the right side of the car. You can observe it when you walk on the road.If you park at the fuel tank of a roadside car, you will find that most of them are on the right side of the car.

The reasons why some car fuel tank caps are on the left and some on the right are as follows: Body counterweight: Some vehicle manufacturers pay more attention to the balance of the body counterweight, such as German. If a steering system is added to the front engine, the front of the car will become heavier as a whole.

The driving direction is different: in fact, the position of the fuel tank mouth is also closely related to the driving direction of different countries.

Many people must have made such a mistake. Sometimes when driving someone else's car to refuel, they find that the position of the fuel tank is not in the same position as that of your own. Then he moved the car back and forth awkwardly.

Because it is driven on the right in China and the overtaking area is on the left, the fuel tank is on the right.Of course, some imported cars made in Japan have not been improved locally, so the fuel tank is still kept in the left rear. Adjusting the fuel tank is relatively complicated, so the manufacturer will only adjust the placement of the driver's seat.

What is the fuel tank sign?

1. Generally speaking, the fuel tank symbol E of the car dashboard represents an empty fuel tank, and F represents a full fuel tank. The sign of the fuel tank represents the warning prompt of the car's fuel tank. The fuel tank ef represents the meaning of the excess fuel in the fuel tank respectively.

2. The fuel tank sign is the appearance of a refueling machine. The color is yellow. There is an arrow on the sign. The arrow is on the left, which proves that the vehicle's refueling port is on the left. The arrow is on the right, which proves that the vehicle's refueling port is on the right. After the fuel tank sign appears on the vehicle dashboard, it must be refueled as soon as possible.

3. Represents the position of refueling. According to China Automobile Network, the logo of the fuel tank, the logo of the fuel tank is like an oil tank truck, the color is yellow, and there is an arrow on the logo. The arrow is on the left, indicating that the refueling port of the vehicle is on the left, and the arrow is on the right, indicating that the refueling port of the vehicle is on the right, so the logo pattern of the fuel tank represents the position of refueling.

4. The fuel tank sign is the appearance of the refueling machine. The color is yellow. There is an arrow on the logo. The arrow is on the left, proving that the refueling port of the vehicle is on the left, and the arrow is on the right, proving that the refueling port of the vehicle is on the right. After the fuel tank sign appears on the vehicle instrument, it must be refueled for the first time.

5. The logo of the fuel tank looks like an oil tanker, and the color is yellow. There is an arrow on the sign. The arrow is on the left, indicating that the vehicle's refueling port is on the left, and the arrow is on the right, indicating that the vehicle's refueling port is on the right.After the fuel tank sign appears on the dashboard of the vehicle, you need to refuel as soon as possible.

There is a triangular arrow on the fuel tank on the dashboard. Whichever it points to indicates which side the fuel tank cover outside the car is?

1. Some fuel tanks are on the right and some cars are on the left.The fuel port of the fuel tank can be distinguished through the fuel gauge light of the vehicle. There is an arrow icon on the fuel gauge of the dashboard of the car. Wherever this arrow icon is biased, the fuel tank is on which side.

2. Most models have a fuel tank mark on the dashboard. There will be an arrow mark near the fuel tank mark. Whichever the arrow points to, the refueling port is on which side of the car.

3. In the position of the fuel volume in the car dashboard, find the small mark of the fuel tank. There is usually an arrow next to that mark. The direction of the arrow is the direction of the fuel tank cap. If there is no arrow, you can observe whether the fuel gauge is on the left or right side of the dashboard, which represents the position of the fuel tank cap.

4. The small triangle arrow of the fuel tank indicator light tells the owner where the refueling port is, such as carThere is a right yellow arrow on the fuel tank logo on the car's instrument, indicating that the fuel tank refueling port of the car is on the right.

What's the difference between the car's fuel tank? After reading the knowledge

The car fuel tank is mainly used to store oil to provide fuel for the vehicle. Its position is on the left or right. In essence, there is no difference and it will not affect its function. The reason why there is a left and right division is mainly based on the following reasons: First, for the body weighting.

First of all, we should know that whether the car's fuel tank is on the left or on the right, it is set at the rear of the car. This is because there is an engine and gearbox in the front of the car, and the weight is relatively large, so a certain quality of things need to be added to the rear of the car to stabilize the center of gravity, so the fuel tank becomes the first choice.

In fact, whether the car fuel tank is on the left or on the right has a lot to do with international driving rules. Generally, the fuel tanks of Japanese and Korean cars are on the left, because the driving rules of Japan and South Korea are to drive on the left. This design can prevent two cars from crashing into the fuel tank when they collide. Explode.

If the driver's seat is on the left, the fuel tank will generally be set on the right side of the rear of the car, and this method is also commonly used in China and Germany.

What is the structural composition of the fuel tank in the car?

The main structure of the automobile fuel tank is composed of oil pipe, tank, gasoline tank cover, gasoline meter, gasoline pump, etc. The function of the car fuel tank: in liquidIn the pressure system, the fuel tank not only stores the oil, but also plays the role of dissipating heat, separating bubbles and precipitated impurities in the oil.

Automotive fuel tank structure Gasoline tank cover The gasoline tank cover is usually designed to be a claw type and clamps the perimeter of the gas tank mouth with the rubber gasket pressed by the wavy spring to ensure sealing. Some covers are also designed with a deadlock device to prevent falling off or loss.

The fuel tank 5 consists of two welded parts and is stamped with lead steel. There is a diaphragm inside the fuel tank to prevent fuel from splashing and increase structural rigidity. The fuel tank refueling port, which is enclosed by the refueling port cover, is welded to the upper part of the fuel tank. Some cars are equipped with retractable fuel tank refueling ports to improve the refueling of the fuel tank.

There is a partition inside the fuel tank to prevent fuel from splashing and increase structural rigidity. Oil sealed by the refueling port coverThe tank refueling port is welded to the upper part of the fuel tank, and some cars have retractable fuel tank refueling ports to improve the refueling of the fuel tank.

The fuel tank is equipped with a metal grid to prevent gasoline from shaking and impacting in the fuel tank. In addition, there is a float sensor that displays the amount of fuel, and a tank sewage hole. There are reinforcements at the bottom and around the fuel tank to prevent deformation of the fuel tank. Then there is the oil suction pipe for vehicles.

When the car goes up and down, accelerates and decelerates, the oil in the fuel tank will shake. So how to design the inside the fuel tank to ensure that the oil pump will not fail to absorb oil due to oil shaking during driving, and the oil level is low? The structure of the old gasoline pump is simple and rough, with a bracket, a pump core, and a coarse filter on the oil intake.
