The movement of the connecting rod causes the fixed column to move along chute B, and the movement of the fixed column drives the fixed arm to move, thereby causing the mixed fuel pressure stabilizing tank to displace. When the mixed fuel pressure stabilizing tank is adjusted to the specified height, the adjusting handle is released to allow the stainless steel spring to release elastic force, and the insertion column is reinserted into the inner position of the insertion hole, thus completing the height adjustment of the mixed fuel pressure stabilizing tank. Through this adjustment method, it is more convenient to adjust the height.

[0017] 2. The fixed column at the left end position of the fixed arm is inserted into chute B in the support frame, and the connecting rod is inserted into the inner position of the fixed column. In this way, when the connecting rod moves, it can drive the fixed column to move, and the movement of the fixed column further changes the height of the mixed fuel pressure stabilizing tank.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0025] The utility model provides an ammonia-ether mixed fuel supply device for an engine test room as shown in Figures 1-5 which includes a mixed fuel pressure stabilizing tank 1. A fixed arm 2 is fixed at the left end position of the mixed fuel pressure stabilizing tank 1. A fixed column 22 is fixed at the left end position of the fixed arm 2. The fixed arm 2 is inserted and installed with a support frame 4 at the left end position through the fixed column 22. The slide groove B 18 at the right end position of the support frame 4 is used to connect with the fixed column 22. A plurality of insertion holes 16 are distributed at the front end position of the support frame 4. A slide groove A 15 is arranged at the front end position of the support frame 4. Among them, the slide groove A 15 and the insertion holes 16 communicate with each other. The support frame 4 is installed with an adjusting handle 3 at the front end position through the slide groove A 15 and the insertion holes 16. An insertion column 20 for inserting into the internal position of the insertion hole 16 is fixed at the inner side position of the adjusting handle 3. A connecting rod 17 is fixed at the inner side position of the insertion column 20. At the same time, the connecting rod 17 is inserted into the internal position of the fixed column 22. A fixed plate 21 is fixed at the outer wall position of the connecting rod 17. A stainless steel spring 19 is fixed at the lower end position of the fixed plate 21. The mixed fuel pressure stabilizing tank 1 is connected with the pneumatic pump main body 14 through a connecting pipe at the lower end position. The pneumatic pump main body 14 is connected with the mixed fuel pressure stabilizing tank 1 through a pneumatic pump outlet valve 5 at the upper right side position. A four-way pipe fitting 7 is arranged at the upper left side position of the pneumatic pump main body 14. The four-way pipe fitting 7 is connected with the main body 10 of the return oil cooling device through a connecting pipe. The return oil cooling outlet 8 at the right end position of the main body 10 of the return oil cooling device is used to connect with the pneumatic pump main body 14. The rear end position of the four-way pipe fitting 7 is communicated with the ammonia-ether flowmeter 12 through a connecting pipe.

[0026] During the working process, the ammonia-ether mixed fuel is first sucked out from the mixed fuel pressure stabilizing tank 1 by a pneumatic pump, the flow rate is measured by the ammonia-ether flowmeter 12, and then it enters the engine through the pneumatic pump outlet valve 5 for combustion. The exhaust gas after combustion is discharged through the exhaust valve, and part of it flows to the oil return cooling device for cooling and then recirculates. At the same time, the oil return cooling inlet 9 and the return water valve control the water inlet and return water of the cooling device to ensure the stable operation of the system circulation, so as to achieve the purpose of supplying the ammonia-ether mixed fuel to the engine. The normal operation of the fuel supply equipment and the smooth progress of the laboratory test are ensured through the cooperation of these structures.

[0027] As Figure 1 and Figure 4 shown, the valve at the left end position of the ammonia-ether flowmeter 12 is used to connect with the liquid sampling port manual valve. The oil return cooling device return water valve 11 is arranged at the upper left end position of the oil return cooling device main body 10, the oil return cooling inlet 9 is arranged at the upper right end position of the oil return cooling device main body 10, the oil return cooling inlet 9 is connected with the engine oil return, the oil return cooling device water inlet valve 13 is arranged at the lower right end position of the oil return cooling device main body 10, and the ammonia-ether mixed fuel exhaust valve 6 is arranged at the front end position of the four-way pipe fitting 7.

[0028] As Figure 1 and Figure 2 shown, when the adjusting handle 3 is pulled outward, the fixing plate 21 squeezes the stainless steel spring 19. When the adjusting handle 3 is pulled outward, the insertion column 20 disengages from the insertion hole 16. When the insertion column 20 disengages from the insertion hole 16, the connecting rod 17 can move up and down along the chute A15. The movement of the connecting rod 17 drives the fixing column 22 to move along the chute B18. The movement of the fixing column 22 can adjust the height of the mixed fuel pressure stabilizing tank 1. When the adjusting handle 3 is released, the stainless steel spring 19 releases the elastic force, and the stainless steel spring 19 releasing the elastic force causes the insertion column 20 to insert into the inner position of the insertion hole 16.

[0029] The fixing column 22 at the left end position of the fixed arm 2 is inserted into the chute B18 in the support frame 4, and the connecting rod 17 is inserted into the inner position of the fixing column 22. In this way, when the connecting rod 17 moves, it can drive the fixing column 22 to move, and the movement of the fixing column 22 changes the height of the mixed fuel pressure stabilizing tank 1.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
