Abstract:
A piston sleeve for a high compression internal combustion engine comprising:a tubular member having a top surface, a tubular member axis, and a bottom surface; a radial positioning surface adjacent to the top surface; an axial positioning surface that faces axially toward the bottom surface and is between the top surface and the bottom surface; a radially outward facing coolant contact surface between the radial positioning surface and the axial positioning surface; a skirt extending from the axial positioning surface to the bottom surface; and a profiled radially inward facing surface extending substantially from the top surface to the bottom surface that becomes substantially cylindrical when the piston sleeve is mounted in the high compression internal combustion engine and a predetermined axial compression force is applied to the top surface and to the axial positioning surface.
