-14- ABSTRACT A method is disclosed of modifying a con- ventional internal combustion engine to accept ceramic material. A cast iron extension member is metal- lurgically joined to the cast iron engine block, the extension member having a wall defining a bore opening aligned with and larger than the bore opening of the engine block. The extension member has a height sub- stantially equal to or greater than the axial stroke of the piston. The diameter of the upper portion of the wall, defining the bore opening in the engine block, is enlarged to define an annular shoulder; the shoulder has an outer surface substantially axially aligned with the wall defining the bore opening in the extension member. A cylindrical ceramic liner, such as zircon or alumina, is attached within the wall of the bore opening of the extension member by use of a high strength metallic sleeve which is fitted along the outer surface of the shoulder. The ceramic liner has an internal surface aligned with the wall of the bore opening in the engine block. A metallic cap (comprised of stainless steel or cast iron) is attached to the top of the piston, the cap carrying a ceramic facing. The cap has an effective height commensurate with the effective height of the extension member. The cap defines a trapped air space between the ceramic facing and piston, and the cap has its side wall aligned with the side wall of the piston.
