By setting up a filling chamber and filling it with a thermal expansion medium, the sealing ring is placed in the sealing groove of the engine cylinder block and cylinder head. After the engine is started, as the temperature increases, the internal pressure also increases. The increased temperature can cause the thermal expansion medium in the filling chamber to expand. Then, through the expanded thermal expansion medium, the expansion ring expands, and the outer elastic layer is pressed against the sealing groove, increasing the sealing performance.
