[0021] This utility model embodiment provides a wear-resistant engine cylinder liner, such as Figures 1-4 As shown, the wear-resistant engine cylinder liner includes: a cylinder liner body 1, with a fixed inner ring 2 inside the cylinder liner body 1, and a wear-resistant coating 3 on the inner wall of the fixed inner ring 2; a protective outer layer 4, which is disposed on the outer side of the cylinder liner body 1; and a threaded cylinder 5, which is rotatably mounted on the cylinder liner body 1, with a threaded rod 6 threaded inside the threaded cylinder 5, one end of which extends to the outside of the threaded cylinder 5 and is fixed to the fixed inner ring 2.

[0022] In this embodiment, the cylinder liner body 1 serves as the main structure of the cylinder liner, bearing the pressure and friction inside the engine. A fixed inner ring 2 is disposed inside the cylinder liner body 1, and a wear-resistant coating 3 is applied to the inner wall of the fixed inner ring 2, significantly improving the wear resistance of the cylinder liner and effectively reducing wear on the inner wall of the cylinder liner. This avoids the problem of increased inner diameter and extends the service life of the cylinder liner. A protective outer layer 4 is disposed on the outer side of the cylinder liner body 1, primarily serving a protective function to prevent damage to the cylinder liner body 1 due to external environmental factors (such as corrosion, high temperature, etc.), further enhancing the durability of the cylinder liner. A threaded sleeve 5 is rotatably mounted on the cylinder liner body 1, providing a convenient adjustment mechanism through a threaded connection. One end of the threaded rod 6 extends to the outside of the threaded cylinder 5 and is fixed to the inner ring 2. By rotating the threaded cylinder 5, the tightness of the threaded rod 6 to the inner ring 2 can be adjusted, thereby adjusting the cylinder liner inner diameter to a certain extent or ensuring the stable installation of the wear-resistant coating 3. This improves the flexibility and stability of the cylinder liner structure. By setting the inner ring 2 and the wear-resistant coating 3, the wear resistance of the cylinder liner is significantly improved, and the service life is extended. The protective outer layer 4 enhances the cylinder liner's resistance to the external environment and improves the overall durability. The design of the threaded cylinder 5 and the threaded rod 6 provides a flexible adjustment mechanism, which is convenient for installation and adjustment, and ensures the stability of the cylinder liner inner diameter and the stability of the wear-resistant coating 3.

[0023] In a further preferred embodiment of the present invention, a rotating block 7 is fixedly installed at one end of the threaded cylinder 5, and a rotating groove 8 is provided on the outer wall of the rotating block 7 to facilitate rotation.

[0024] In this embodiment, the rotating block 7 is fixedly installed at one end of the threaded cylinder 5. As a component that facilitates operation by the user or tool, its design allows the user to rotate the threaded cylinder 5 more easily without having to directly hold the threaded cylinder 5 itself. This improves the convenience and efficiency of operation. The rotating groove 8 is located on the outer wall of the rotating block 7 and is usually designed in the shape of a groove so that the user's fingers or a special rotating tool can more easily grasp and rotate the rotating block 7. The design of the rotating groove 8 not only increases the convenience of rotation but also improves the safety of operation because the user can control the rotation process more stably. The design of the rotating block 7 and the rotating groove 8 significantly improves the ease of operation of the threaded cylinder 5, allowing the user to rotate the threaded cylinder 5 more easily and quickly, thereby adjusting the tightness of the threaded rod 6 on the fixed inner ring 2. This design also improves the safety of operation because the user can control the rotation process more stably, reducing the risk of accidents caused by slipping or improper operation.

[0025] In a further preferred embodiment of the present invention, the inner wall of the protective outer layer 4 is provided with a slot 9, which corresponds to the rotating block 7.

[0026] In this embodiment, the slot 9 is located on the inner wall of the protective outer layer 4, corresponding to the rotating block 7. The slot 9 is designed to accommodate the rotating block 7. When the threaded cylinder 5 and the rotating block 7 rotate on the cylinder liner body 1, the slot 9 provides an additional space to prevent the rotating block 7 from interfering with or colliding with the protective outer layer 4. The design of the slot 9 ensures the smoothness of the rotating block 7 during rotation, avoiding operational difficulties or damage caused by interference or collision. This design also improves the overall structural stability of the cylinder liner, because the rotation of the rotating block 7 and the threaded cylinder 5 is not restricted by the protective outer layer 4, thereby ensuring the adjustment accuracy of the cylinder liner inner diameter and the stability of the wear-resistant coating 3. In addition, the slot 9 can also serve as an additional heat dissipation channel, which helps to reduce the temperature of the cylinder liner during operation and improve the reliability and durability of the engine.

[0027] In a further preferred embodiment of the present invention, the outer wall of the protective outer layer 4 is provided with heat dissipation fins 10 for accelerating heat dissipation.

[0028] In this embodiment, the heat dissipation fins 10 are disposed on the outer wall of the protective outer layer 4. Their main function is to increase the heat exchange area between the cylinder liner and the surrounding environment, thereby accelerating the heat dissipation speed and reducing the temperature of the cylinder liner during operation. The heat dissipation fins 10 are usually designed as thin sheets and are evenly distributed on the outer wall of the protective outer layer 4 to improve heat dissipation efficiency. The design of the heat dissipation fins 10 significantly improves the heat dissipation performance of the cylinder liner, helps to reduce the temperature of the cylinder liner during operation, and extends the service life of the cylinder liner and other engine components. By accelerating the heat dissipation speed, the heat dissipation fins 10 also help to improve the reliability and durability of the engine and reduce the risk of failure due to overheating. In addition, the design of the heat dissipation fins 10 also enhances the overall aesthetics of the cylinder liner and improves the market competitiveness of the product.

[0029] In a further preferred embodiment of the present invention, a guide rod 11 is fixedly installed on one side of the fixed inner ring 2. The guide rod 11 slides through the cylinder liner body 1, and the cylinder liner body 1 is provided with a through-hole 12 for the guide rod 11 to pass through.

[0030] In this embodiment, the guide rod 11 is fixedly installed on one side of the fixed inner ring 2. Its design purpose is to provide stable support and guidance for the fixed inner ring 2. The guide rod 11 slides through the cylinder liner body 1 to ensure the stable position of the fixed inner ring 2 within the cylinder liner body 1 and prevent it from shifting due to uneven force or vibration. The through-hole 12 is provided on the cylinder liner body 1 for the passage of the guide rod 11. The design of the through-hole 12 ensures that the guide rod 11 can slide smoothly through the cylinder liner body 1 without any obstruction. The design of the guide rod 11 and the through-hole 12 significantly improves the stability and reliability of the cylinder liner structure. The guide rod 11 provides additional support for the fixed inner ring 2, preventing it from shifting due to uneven force, thereby ensuring the stability of the cylinder liner inner diameter and the stability of the wear-resistant coating 3. It also helps to improve the vibration resistance of the cylinder liner because the guide rod 11 can absorb and disperse vibration energy to a certain extent, reducing the risk of cylinder liner damage caused by vibration.

[0031] In a further preferred embodiment of the present invention, the outer wall of the protective outer layer 4 is provided with a groove 13, and an elastic sealing ring 14 for contacting the inner wall of the cylinder is embedded in the groove 13.

[0032] In this embodiment, the slot 13 is located on the outer wall of the protective outer layer 4. Its main function is to provide a space for fixing and supporting the elastic sealing ring 14. The design of the slot 13 ensures that the elastic sealing ring 14 can be firmly installed on the protective outer layer 4, and is not easy to fall off or shift. The elastic sealing ring 14 is embedded in the slot 13. Its design purpose is to make close contact with the inner wall of the engine cylinder to form an effective seal. The elastic sealing ring 14 is usually made of a material with good elasticity and wear resistance to ensure that a stable sealing effect can be maintained during engine operation. The design of the elastic sealing ring 14 and the slot 13 significantly improves the sealing performance between the cylinder liner and the engine cylinder. This helps to prevent the leakage of lubricating oil or coolant, keep the engine interior clean and in normal working condition. By providing a tight seal, the elastic sealing ring 14 also helps to reduce friction and wear between the cylinder liner and the cylinder, and extend the service life of the cylinder liner and the engine.

[0033] In a further preferred embodiment of the present invention, the inner wall of the wear-resistant coating 3 is provided with an oil storage layer 15, and the oil storage layer 15 is provided with a plurality of microporous structures for adsorbing and storing lubricating oil.

[0034] In this embodiment, the oil reservoir 15 is disposed on the inner wall of the wear-resistant coating 3. Its main function is to store lubricating oil so as to continuously provide lubrication to the inner wall of the cylinder liner during engine operation. The oil reservoir 15 is usually made of a material with a porous structure. The microporous structure is located on the oil reservoir 15 and is the basis for the porous structure of the oil reservoir 15. These microporous structures have extremely high specific surface area, which can adsorb and store a large amount of lubricating oil, ensuring that the inner wall of the cylinder liner is always adequately lubricated during engine operation, reducing friction and wear between the cylinder liner and the piston, extending the service life of the cylinder liner and the piston, and also helping to improve the fuel economy and operating efficiency of the engine, because good lubrication can reduce the internal frictional resistance of the engine, thereby reducing fuel consumption and energy loss.

[0035] In summary, compared with related technologies, this device significantly improves the wear resistance, lubrication efficiency, heat dissipation performance, and sealing reliability of engine cylinder liners. It also simplifies the installation and maintenance process. These improvements work together to extend the service life of the cylinder liners and the engine, improve the engine's fuel economy and operating efficiency, reduce maintenance costs, and provide a solid guarantee for the efficient, stable, and reliable operation of the engine.
