Many car owners, when driving a friend's car to refuel, tend to habitually refuel according to one side of their car's fuel tank, only to realize that the fuel tank is on the other side.

 

Upon closer observation of the cars coming to the gas station to refuel, it was found that many cars have different fuel ports, some on the left and some on the right. So the question is, why do car fuel ports need to be divided into left and right sides? Isn't it more convenient to unify one side?

 

In fact, there are no strict requirements for the position of the fuel tank and lid, and there is no unified standard on *. They are all determined based on the design and chassis layout of the vehicle model.

 

Moreover, the position of the fuel tank has no impact on the performance of the car, so we don't need to be overly concerned about it. If we really want to talk about it, then there are four main factors that determine the position of the fuel tank opening:

 

Direction of travel determination

 

We all know that the driving rules on * can be divided into two categories: driving on the left and driving on the right. The position of the fuel tank opening is also directly related to these two different driving rules.

 

For example, in Germany and Sweden, which drive on the right, for the convenience of refueling, the fuel tank port is usually on the right side, while in Japan and other countries that drive on the left, the fuel tank port is set on the left side, which is directly reflected in the cars produced by these vehicles.

 

Of course, not all car models comply with this rule.

 

Road * considerations

 

From the perspective of *, arranging the fuel tank opening on the diagonal of the driver's seat can avoid accidents during refueling.

 

In addition, due to the close distance between the vehicle body and the fuel dispenser, if the fuel tank port is designed on the same side as the driver, it will cause inconvenience in opening the car door or getting in and out of the vehicle.

 

Improve refueling efficiency

 

For car owners, the position of the fuel tank cap varies among different vehicle models, which can also improve refueling efficiency. This way, vehicles with left and right fuel tank caps can refuel simultaneously, saving more queuing time.

 

Balancing body weight

 

For vehicles equipped with front wheel drive, the vehicle manufacturer will consider the issue of body weight balance and adopt a rear fuel tank to balance the weight difference between the front engine and the driver.

 

And whether to place it on the left or right depends on the position of the cockpit, because the position of the fuel tank diagonally opposite the driver's seat is more conducive to balancing the overall weight of the car.

 

How to determine the position of the fuel tank port

 

The position of the fuel tank port is different for each vehicle model. When refueling, we only need to observe the dashboard to know which side the fuel tank is on. The arrow to the right indicates that the fuel tank port is on the right side of the vehicle, and vice versa.
