The present scheme provides a protection component 2 to limit the water sealing ring on the engine cylinder liner, thereby ensuring the sealing effect of the water sealing ring and reducing the wear and deformation of the water sealing ring in long-term use, thereby ensuring the normal use of the engine; at the same time, the connecting column 25 and the insertion rod 22 in the protection component 2 ensure that the structure is easy to install and disassemble, thereby improving the usability of the cylinder liner.

[0028] according to Figure 1 The outer surface of the cylinder liner body 1 is provided with a heat dissipation paint, and by providing the heat dissipation paint, it is ensured that the cylinder liner has a good heat dissipation effect when in use.

[0029] according to Figure 1-2 The protection component 2 includes a first annular protection ring 21 and a second annular protection ring 24. The first annular protection ring 21 is snap-connected in the installation groove 3. Connecting columns 25 are fixedly connected at both ends of the first annular protection ring 21.
