A heat-resistant steel ring, ceramic ring, etc. is inserted into the inner circumferential surface of the cylinder liner 1 above the position reached by the top ring 4, and a gap is formed between the heat-resistant steel ring or ceramic ring and the cylinder liner to prevent air convection, thereby insulating the cylinder liner. Insulated cylinder liner structure.
