Abstract
Abstract A cylinder head and engine block assembly for internal combustion engine includes a cylinder head formed from a fiber-reinforced phenolic resin, and an engine block formed from a fiber-reinforced phenolic resin, and an arrangement for placing the head and block assembly under a loading compression pressure; preferably the fiber reinforcement is made up of fibers of fiberglass or graphite having a length of about 1/8" to 1"; the cylinder head body has embedded in or united with it a unitary metal insert defining the upper portion of at least one inlet port and at least one exhaust port and combustion chamber, the block has embedded in or united with it a unitary metal unit defining at least one cylinder liner, and the block has upper bearing supports embedded in or united with the block.
