Head gasket for an engine

An engine comprising:

• a cylinder head;
• a cylinder liner having a side wall defining a combustion chamber and a liner flange projecting from the side wall in an outward direction away from the combustion chamber, wherein the cylinder liner defines a liner face extending from the side wall to an outer surface of the liner flange, the liner face including a raised land disposed between the side wall and the outer surface of the liner flange;
• and
• a head gasket disposed between the cylinder head and the cylinder liner, the head gasket including:
• a main body layer;
• a flange layer coupled to the main body layer by a flange wrap portion, the flange wrap portion being sized for axial alignment with the side wall of the cylinder liner, the flange layer being spaced from the main body layer to define a gap between the main body layer and the flange layer adjacent the flange wrap portion;
• a core layer coupled to the main body layer and including a sealing bead spaced outwardly from the flange wrap portion and sized for axial alignment with the liner flange;
• and
• a base layer coupled to the main body layer and spaced from the flange layer by a slot sized to receive the raised land.

A head gasket for use in an engine having a cylinder head and a cylinder liner, the cylinder liner including a side wall having a width and defining a combustion chamber having a bore diameter, and a liner flange projecting from the side wall in an outward direction away from the combustion chamber, the head gasket comprising:

• a main body layer;
• a flange layer coupled to the main body layer by a flange wrap portion, the flange wrap portion having a wrap exterior surface defining a flange wrap diameter equal to the bore diameter of the combustion chamber, so that the flange wrap portion is axially aligned with the side wall of the cylinder liner, the flange layer being spaced from the main body layer to define a gap between the main body layer and the flange layer adjacent the flange wrap portion, the gap having a length greater than the width of the side wall of the cylinder liner wherein the cylinder liner defines a liner face extending from the side wall to an outer surface of the liner flange, the liner face including a raised land disposed between the side wall and the outer surface of the liner flanged;
• a base layer coupled to the main body layer and spaced from the flange layer by a slot sized to receive the raised land;
• and
• a core layer coupled to the main body layer and including a sealing bead spaced outwardly from the flange wrap portion and sized for axial alignment with the liner flange.
