CYLINDER HEAD SEALING SYSTEM AND METHOD |
摘要 |
A thermally conductive sealing system for the cylinder head joint (11) of an internal combustion engine (10) is disclosed comprising a spacer plate (24) clamped in direct contact between the cylinder head (12) and the cylinder block (14) and a plurality of discrete fluid gaskets (67, 70) disposed across the spacer plate (24) and clamped between the cylinder head (12) and cylinder block (14). The flange (22) of a cylinder liner (18) is received in a bore (26) of the spacer plate (24) and a combustion gas seal or "fire ring" (32) is clamped in the bore (26) between the cylinder head (12) and the cylinder liner flange (22). The combustion gas seal (32) includes a malleable sealing ring (42) for sealing between the cylinder head (12) and the cylinder liner (18) and a hardened backing ring (44) for supporting the sealing ring (42). The plurality of discrete fluid gaskets (67, 70) includes a removable lifter compartment gasket (70) including sealing elements (78, 80) attached across a substrate (71) and a plurality of coolant ferrules (67) for sealing across coolant ports (60, 62) and around cylinder head bolts (16).
