The position without ion liquid sealing will cause sealing failure, and the sealing failure will cause gas leakage between the piston and the cylinder liner. In addition, part of the ion liquid will also adhere to the inner wall of the cylinder liner and leak with the reciprocating movement of the piston. There is no good solution at present.
