Abstract: A cylinder head is formed by positioning a clad preform including a first and second layer in a casting die cavity with the second layer in communication with the die cavity and the first layer facing outwardly to define a combustion surface. Molten material provided to the die cavity is solidified to form a cast portion metallurgically bonded to the second layer. An aperture of the preform forms a port in fluid communication with a passage of the cast portion. A plurality of dome-shaped preforms may define the combustion chambers of a cylinder head formed by the method. The preform may define a cylinder head face. The first layer may be a steel-based layer, and the second layer and cast portion may be aluminum-based, such that the first layer and combustion surface has higher thermal fatigue strength relative to the cast portion.

Abstract: A valve seat insert including an annular body disposed about a central axis. The annular body includes a radially inward face that defines an orifice and a radially outward face that is opposite the radially inward face. Additionally, the annular body includes a top face, and a bottom face that is opposite the top face. The valve seat insert further includes a plurality of heat transfer protrusions that extend from the radially outward face of the annular body.
