Abstract
A cylinder head includes an inner structural member having a plate forming a deck face of the cylinder head and forming at least one dished cylinder roof, and a plurality of cylinder head bolt columns extending from the plate. An outer member is supported by the inner structural member and forms a cooling jacket, intake ports, and exhaust ports. Passages of the cooling jacket are lined with metal walls in contact with the composite structure of the outer member. A method of forming a cylinder head includes positioning a structural insert and a lost core insert in a tool, and injecting material into the tool to form a body surrounding the structural insert and the lost core insert thereby forming a head preform. The lost core insert is shaped to form a cooling jacket and has a lost core material generally encapsulated in a metal shell.
