[0002] Measuring the lift value of methanol injectors in new energy applications is crucial. It ensures precise methanol fuel injection, optimizes engine combustion efficiency and power output, and reduces pollutant emissions. By accurately measuring the lift value, problems such as nozzle wear and unstable injection pressure can be detected and resolved in a timely manner, extending equipment life and reducing maintenance costs. In addition, the lift value is also an important parameter for achieving precise engine control, which helps improve engine response speed and stability. Therefore, the measurement of the lift value must be given high priority in the design and maintenance of methanol fuel injection systems.

To better understand this invention, a detailed description is provided below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1: Basic Structure of the Measuring Instrument

[0025] like Figures 1 to 3 As shown, this utility model provides a methanol nozzle lift measuring instrument. A methanol nozzle lift measuring instrument includes a base 1, a fixed bracket 2 fixedly installed on one side of the top of the base 1, a clamping cylinder 3 fixedly installed on the top of the fixed bracket 2, a workpiece positioning seat 4 fixedly installed on the top of the base 1, a methanol nozzle workpiece 5 placed on the top of the workpiece positioning seat 4, a connecting plate 6 fixedly installed on the telescopic end of the clamping cylinder 3, a horizontal plate 7 fixedly installed on the side of the connecting plate 6, a probe pressurizing cylinder 8 fixedly installed on the top of the horizontal plate 7, an inductive sensor 9 set on the top of the horizontal plate 7, a probe pressurizing fixture 10 set below the horizontal plate 7 on the connecting plate 6, a probe body 16 movably installed inside the probe pressurizing fixture 10, and pressurizing fixture lifting springs 17 fixedly installed on both sides of the probe body 16. During measurement, the clamping cylinder 3 presses down, causing the probe body 16 inside the probe pressurizing fixture 10 to extend from the top of the methanol nozzle workpiece 5 for measurement, with a 2mm gap between the probe bodies 16.

[0026] The clamping cylinder 3, the probe pressurizing cylinder 8, and the inductive sensing head 9 are all existing technologies, and their specific structures have been disclosed and will not be described in detail here. The clamping cylinder 3, the probe pressurizing cylinder 8, and the inductive sensing head 9 are all equipped with power supplies.

[0027] The methanol nozzle component 5 includes a housing, a methanol nozzle valve stem 501, an iron core spring 502, a methanol nozzle iron core 503, and a ball head 504. The methanol nozzle valve stem 501 is slidably installed inside the housing. One end of the iron core spring 502 is fixedly connected to the methanol nozzle valve stem 501. The methanol nozzle iron core 503 is fixedly connected to the housing. The ball head 504 is fixedly connected to the methanol nozzle valve stem 501. The methanol nozzle orifice can effectively improve the combustion efficiency and power performance of the engine, while also reducing exhaust emissions and lowering environmental pollution.

[0028] Example 2: Design of the limiting block

[0029] An L-shaped plate 11 is fixedly installed on the side of the fixed frame 2 near the workpiece positioning seat 4. A limit block 12 is fixedly installed on the top of the L-shaped plate 11. By setting the limit block 12, the movement of the clamping cylinder 3 is limited.

[0030] Example 3: Slider Structure and Function

[0031] A slider 13 is fixedly installed on one side of the fixed frame 2. The connecting plate 6 is slidably connected to the slider 13. The slider 13 enhances the stability of the moving connecting plate 6, thereby improving the measurement accuracy.

[0032] Example 4: Design and Function of Guide Blocks

[0033] A through hole 14 is provided at the top of the horizontal plate 7. The inductive sensor 9 passes through the through hole 14. A guide block 15 is fixedly installed on the connecting plate 6 below the horizontal plate 7. The inductive sensor 9 is movably inserted into the guide block 15. The inductive sensor 9 is directionally limited by the guide block 15 to avoid the position of the inductive sensor 9 from shifting and affecting the measurement value.

[0034] Example 5: Working principle of the measuring instrument

[0035] During measurement, the methanol nozzle workpiece 5 is clamped by the workpiece positioning seat 4, and the pressing cylinder 3 is pressed down. After being positioned by the limit block 12, the workpiece is pressed. At this time, the probe body 16 inside the probe pressurizing fixture 10 extends from the top of the methanol nozzle workpiece 5 and contacts the ball head 504 inside the methanol nozzle workpiece 5. The upper end of the probe body 16 contacts the inductive sensor 9. Before the probe pressurizing cylinder 8 is pressed down, the pressing fixture lifting springs 17 on both sides inside the probe pressurizing fixture 10 offset the weight of the probe pressurizing fixture 10 itself. At this time, the ball head 504 inside the methanol nozzle workpiece 5 is mainly subjected to the probe spring force (0.3N) of the inductive sensor 9 plus the weight of the probe body 16 itself, which is much less than the force (3-5N) of the iron core spring 502 at the bottom of the methanol nozzle valve stem 501. At this time, the ball head 504 is in the reset state, and the value L1 of the inductive sensor 9 is recorded once.

[0036] Then the probe pressurizing cylinder 8 is started, which drives the probe pressurizing fixture 10 to move downward. The probe body 16 presses the ball head 504 downward until the lower end face of the methanol nozzle valve stem 501 component is in close contact with the upper end face of the methanol nozzle iron core 503 and maintains balance. At this time, the methanol nozzle workpiece 5 is in the energized working state. At this time, the value L2 of the inductor 9 is recorded.

[0037] The lift value = L1 - L2, which is the difference between the pressurized and unpressurized states of the probe fixture.

[0038] Technical effect

[0039] Through the detailed description of the above embodiments, this utility model demonstrates significant advantages in the application of lift measurement. By configuring the clamping cylinder 3, workpiece positioning seat 4, probe pressurizing cylinder 8, probe pressurizing fixture 10, inductive sensing head 9, probe body 16, and pressurizing fixture lifting spring 17, automatic measurement of methanol nozzle lift can be achieved, improving measurement accuracy, reducing the labor intensity of workers, and enhancing practicality.

[0040] In summary, this utility model provides a methanol nozzle lift measuring instrument with reasonable structure, complete functions, and strong applicability. It can realize the automatic measurement of methanol nozzle lift, improve measurement accuracy, reduce the labor intensity of workers, and has broad application prospects.
