Abstract
An engine cylinder head comprising an internal metal structure formed from a metal material and an external polymer composite structure formed from a polymer composite material, wherein the external polymer composite structure at least partially surrounds the internal metal structure.
Claims20
An engine cylinder head comprising:
- an internal metal structure, forming an upper portion of a combustion chamber, formed from a metal material;
- and
- an external polymer composite structure formed from a polymer composite material,
- wherein the external polymer composite structure at least partially surrounds the internal metal structure.
1 more element
An engine cylinder head comprising:
- an internal metal structure formed from a metal material;
- and
- an external polymer composite structure formed from a polymer composite material,
- wherein the external polymer composite structure at least partially surrounds the internal metal structure and wherein the external polymer composite structure includes one or more intake and exhaust oil feeds for a hydraulic lash adjuster.
1 more element
An engine cylinder head comprising:
- an internal metal structure, arranged to form an upper portion of a combustion chamber, formed from a metal material and including a fire deck;
- and
- an external polymer composite structure formed from a polymer composite material including a fiber material and including one or more intake and exhaust oil feeds for a hydraulic lash adjuster, one or more spark plug pockets, and one or more direct injection pockets,
- wherein the external polymer composite structure at least partially surrounds the internal metal structure.
1 more element
A method of forming an engine cylinder head comprising:
- forming an internal metal structure of a metal material arranged to form an upper portion of a combustion chamber;
- and
- molding an external polymer composite structure of a polymer composite material over the internal metal structure so that the external polymer composite structure at least partially surrounds the internal metal structure.
