ABSTRACT:
A valve seat arrangement is provided in which a ceramic valve seat is secured to a valve seat holder. The valve seat holder is directly connected to the cylinder head of the block of the internal combustion engine between the exhaust passage and the combustion chamber of the engine. The cylinder head is made of cast aluminum. Due to the differences in the coefficient of heat of the various metals, the ceramic valve seat will be securely retained in the cylinder head.
