ABSTRACT:
A cylinder liner assembly for an internal combustion engine is disclosed. The assembly includes a cylinder head, a cylinder block defining a top deck surface and a cylinder bore extending from the top deck surface, and a cylinder liner mounted in the cylinder bore. The cylinder liner includes a flanged end extending over the top deck surface of the cylinder block. A hardened annular deck plate is provided about the cylinder bore between the flanged end of the cylinder liner and the cylinder block to prevent cracking of the cylinder block when the flanged end is clamped between the cylinder head and the cylinder block. The hardened annular deck plate has a hardness in the range of about 25 to about 60 on a Rockwell "C" scale, and preferably about 50 on a Rockwell "C" scale.
