Description

Technical Field

[0001] This utility model relates to the field of cylinder liners, and in particular to a cylinder liner oil removal device. Background Technology

[0002] The cylinder liner is a crucial component in an internal combustion engine, primarily used to protect the cylinder walls and provide a smooth surface for the piston to move freely within. It plays a vital role in reducing friction, improving sealing, and extending engine life.

[0003] Existing technologies, such as the utility model patent with publication number CN205277605U, disclose a semi-dry cylinder liner. This patent adopts a cylindrical sleeve body, the upper part of which is a wet structure and the lower part is a dry structure. The wet structure and the dry structure are integrally formed. The inner wall of the top opening of the wet structure is provided with an anti-wear annular groove, and the outer wall of the top opening is provided with a first sealing ring groove. The outer wall of the wet structure below the first sealing ring groove is provided with an equal strength arc-shaped structure along the circumferential direction. The outer wall at the junction of the wet structure and the dry structure is provided with a relief groove, and the upper part of the dry structure is provided with a second sealing ring groove. The axial length of the wet structure accounts for 20-30% of the total length of the cylinder liner, and the wall thickness is designed to be 4.5-10mm according to the size of the cylinder liner inner diameter. The wet structure has a clearance fit with the engine block. The axial length of the dry structure accounts for 80-70% of the total length of the cylinder liner, and the wall thickness is designed to be 2-5mm according to the size of the cylinder liner inner diameter. The outer circle of the dry structure is cylindrical, and the dry structure has an interference fit with the engine block.

[0004] The inventors discovered in daily use that existing cylinder liners easily accumulate carbon deposits, oil stains, metal shavings, and other impurities, especially under high-temperature and high-pressure operating environments. Once these dirt and carbon deposits accumulate, they increase the difficulty of cleaning. Removing these substances requires complex cleaning methods and special cleaning agents, which not only increases maintenance costs but also damages the surface of the cylinder liner. Since the inner wall of the cylinder liner is in close contact with the piston and other components, the cleaning process usually requires disassembling the entire engine or performing partial disassembly, making the cleaning work tedious and time-consuming. Particularly in some large engines or internal combustion engines, the cleaning process also requires the use of high-pressure cleaning equipment and chemical cleaning agents. Improper operation can lead to cleaning agent residue, further affecting engine performance.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

[0014] The effect achieved by the above components is that the protective pad can protect the outer shell and prevent excessive wear and tear on the outer shell during use.

[0015] Preferably, the connecting rod has a circular cross-section and is made of stainless steel.

[0016] The effect achieved by the above components is that the connecting rod can increase its service life and prevent it from rusting during use.

[0017] Preferably, a plurality of the brushes are evenly distributed on the auxiliary plate, and the brushes are nylon brushes.

[0018] Compared with related technologies, the cylinder liner degreasing device provided by this utility model has the following beneficial effects:

[0019] By designing a cleaning structure, it is found that existing technologies often result in the accumulation of carbon deposits, oil stains, metal shavings, and other impurities inside the cylinder liner. This is especially problematic under high-temperature and high-pressure operating environments, where the buildup of these deposits significantly increases the difficulty of cleaning. Removing these substances requires complex cleaning methods and specialized cleaning agents, which not only increases maintenance costs but also damages the cylinder liner surface. Since the cylinder liner's inner wall is in close contact with the piston and other components, the cleaning process typically requires disassembling the entire engine or performing partial disassembly, making the cleaning work tedious and time-consuming. Particularly in large engines or internal combustion engines, the cleaning process also requires high-pressure cleaning equipment and chemical cleaning agents. Improper operation can lead to cleaning agent residue, further affecting engine performance. This device achieves convenient double-layer cleaning using a brush and cleaning pad, and it can easily remove oil stains from inside the cylinder liner, greatly improving the efficiency of cylinder liner cleaning.
