Abstract
An engine is made by providing a layer of material between the outer surface of a cylinder liner and the inner surface of the cylinder opening within an engine block. The material can be a polymer or a ceramic. Polyether ether ketone or polyethylene terephthalate can be a polymer used for these purposes. Zirconia or yttria can be ceramic used for these purposes. An electro-deposited paint can serve as the layer of thermally insulative material.
