ABSTRACT:
A cylinder head in an internal combustion engine has a number of valve seat insert bores with a thermally conductive paste applied to an inner surface thereof. A valve seat insert is fitted into each cylinder head bore and the paste fills voids, or air gaps, along the contact surface between the inserts and the bores. The paste is made from a metal powder and a binder material which aggressively bonds to the metal powder, to the inserts and to the bores to form a thermally conductive solid material therebetween.
