Abstract
A cylinder bore liner for an internal combustion engine is formed of a sheet of material in the shape of a non-rectangular parallelogram having oblique edges is formed into a cylindrical liner with the abutting edges vertically offset to form a cylinder of smaller diameter than the diameter of a cylinder bore. The liner is then inserted into the cylinder bore of the engine with the leading edge resting on a ledge in the bore, and the trailing edge protruding from the top of the bore. A force is applied to the protruding edge of the liner to force a sliding motion along the oblique abutting edges which necessarily increases the diameter of the liner until a tight fit is achieved.
