Abstract
A cylinder bore liner insert configured to be cast in an internal combustion engine block includes an additive manufactured liner wall formed during an additive manufacturing process and having an inner surface, an outer surface, and an upper surface configured to be operably associated with a cylinder head, wherein the inner surface at least partially defines a cylinder bore configured to receive a piston therein. A liner water jacket is defined internally within the additive manufactured liner wall during the additive manufacturing process. The liner water jacket at least partially surrounds the cylinder bore to provide cooling thereto via a flow of coolant within the liner water jacket. A plurality of coolant ports are formed in the upper surface and configured to enable flow of coolant between the liner water jacket and the cylinder head.
