Abstract
A multipart ceramic cylinder head construction, comprises: a ceramic plate having (i) opposed faces, (ii) a central zone through which extends a transverse central axis, (iii) a peripheral zone about the central zone, the plate further having three or more gas or fluid transfer openings extending transversely through the central zone and spaced about the central axis to divide the central zone into radial sectors, each sector containing one of the openings; a first ceramic intake port block having sufficient ceramic mass to define a gas passage and define an integral compression receiving portion, the first block being adapted to mate with one of the radial sectors of the plate to align the first passage with the opening in such one radial sector; a second ceramic exhaust port block having sufficient ceramic mass to define a second gas passage and define an integral compression receiving portion, the second block being adapted to mate with another of the radial sectors of the plate to align such second passage with the opening in such other radial sector; and means effective to (i) secure the blocks mated to the plate in compression, and (ii) provide an air gap spacing between the blocks.
