[0016] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0017] like Figure 1-2 As shown, the utility model is a methanol engine fuel adding device, including a cylinder 11 installed on the side of a base 1, a piston 15 is arranged in the cylinder 11, the top of the piston 15 is connected to a lifting plate 17 through a pull rod 16, an induction sensor 18 is installed in the groove at the bottom of the piston 15, and a pressure relief valve that can be opened and closed automatically is correspondingly arranged on the piston 15 to maintain the pressure balance inside and outside the cylinder 11, the lifting plate 17 is connected to the lifting mechanism, and the bottom outlet of the cylinder 11 is connected to an electric nozzle 24 through a short pipe 23. The electric nozzle 24 is an existing device, which can automatically spray the fuel in the cylinder 11 after receiving a command, and a controller 25 is arranged on the base 1.

[0018] By arranging structures such as the pull rod 16, the lifting plate 17, the screw rod 19, the guide rod 2 and the motor 22 that cooperate with each other, the height of the piston 15 can be adjusted as needed, so that the effective volume inside the cylinder 11 can be adjusted to meet the different degrees of fuel addition needs, thereby achieving the purpose of quickly configuring the accurate capacity of fuel, effectively expanding the scope of use of the device, and solving the problem that ordinary fuel adding devices are inconvenient to quickly configure the appropriate capacity of fuel.

[0019] In the above scheme, the liquid inlet on the side of the cylinder 11 is provided with a liquid inlet valve 12, and the liquid inlet valve 12 is connected to the transfer valve 14 through the liquid inlet pipe 13. The liquid inlet valve 12 and the transfer valve 14 are both solenoid valves. The cylinder 11 is connected to the fuel adding mechanism by setting the liquid inlet valve 12, the liquid inlet pipe 13 and the transfer valve 14 in coordination, and then the fuel is sprayed out through the electric nozzle 24, so that the effect of automatically adding fuel to the inside of the engine can be achieved, thereby improving the fuel adding efficiency.

[0020] In the above solution, the outer ring of the piston 15 is provided with a sealing ring. Specifically, the sealing ring can be made of silicone rubber with good sealing effect. The design of the sealing ring improves the sealing effect between the piston 15 and the inner wall of the cylinder 11.

[0021] In the above scheme, the lifting mechanism includes a screw rod 19 and a guide rod 2 arranged in parallel, the screw rod 19 is screwed to the lifting plate 17, and the guide rod 2 is movably connected to the lifting plate 17. Specifically, the bottom ends of the screw rod 19 and the guide rod 2 are installed on the L-shaped support plate, and the end of the screw rod 19 is movably connected to the L-shaped support plate and the fixed plate 21 through a bearing.

[0022] In the above scheme, the top of the screw rod 19 is connected to the output end of the motor 22, and the motor 22 is installed on the fixed plate 21. The motor 22 is a forward and reverse motor, and it is connected to the power supply and the switch through a wire. When working, the motor 22 receives a start signal to drive the screw rod 19 to rotate. During the rotation of the screw rod 19, the lifting plate 17 is driven to move up and down, so that the height of the piston 15 in the cylinder 11 is automatically adjusted through the pull rod 16, and the automatic control of the volume of the cylinder 11 is realized.

[0025] Working principle:

[0026] When the methanol engine fuel adding device is used, the transfer valve 14 is first connected to the fuel adding mechanism through a pipeline, and the liquid inlet valve 12 and the transfer valve 14 are opened to allow the fuel to be added to the cylinder 11 through the liquid inlet pipe 13 until the induction sensor 18 detects the liquid. The controller 25 receives feedback and closes the corresponding valve to stop adding and opens the electric nozzle 24 to spray the fuel inside the cylinder 11. When it is necessary to adjust the internal capacity of the cylinder 11, the user starts the motor 22 to drive the screw rod 19 to rotate, and the lifting plate 17 moves up and down along the guidance of the guide rod 2. At this time, the lifting plate 17 drives the piston 15 to move up and down to the corresponding height through the pull rod 16, thereby achieving the purpose of adjusting the effective volume inside the cylinder 11, which can meet different quantitative addition requirements and expand the effective application range of the device.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
