Description

Technical Field

[0001] The utility model relates to the technical field of fuel additives, and particularly relates to a fuel additive filling device. Background Art

[0002] A fuel additive (also known as gasoline detergent, fuel additive) is a vehicle chemical. Under normal circumstances, proper use of fuel additives can not only remove carbon deposits on automotive parts, but also optimize engine performance, bringing a better user experience to vehicle owners.

[0003] For example, a new type of fuel additive filling device with the application number CN208248874U includes a device main body, a breathable elbow pipe, a spring and an inner bottle pipe. The upper end of the device main body is provided with a rotary cap, the upper end of the rotary cap is provided with a penetrating pipe, the rotary cap is connected with the breathable elbow pipe, the upper end of the breathable elbow pipe is provided with a column, and the upper end of the column is provided with a spring cap.

[0004] Common fuel additives on the market are bottled. Each time they are used, a fixed dose is added, and it is rarely possible to quantitatively proportion the usage amount of the fuel additive according to the amount of fuel filled in the vehicle each time. During the use of the fuel additive, if the fuel additive is added in excess, it will instead cause the carbon deposits in the combustion chamber to increase. By quantitatively proportioning the use of the fuel additive, the carbon removal efficiency of the engine can be improved, and the carbon removal cycle of the engine can be shortened. Therefore, it is urgent to design a fuel additive filling device to solve the above problems. Summary of the Utility Model
