  • Cylinder liner seal arrangement and method of providing the same
    Patent number: 9464591
    Abstract: A cylinder liner sealing arrangement for an internal combustion engine including a cylinder block having cylinder bores, a cylinder head, a cylinder liner within each cylinder bore and a circumferential cut-out formed in the upper and outer surfaces of the cylinder liner. A circular sealing ring is positioned in the circumferential cut-out with the sealing ring contacting at least the cylinder block and the cylinder liner to form a coolant seal therebetween. The sealing ring includes a seal enhancing configuration formed on at least an outer circumferential surface of the sealing ring with the seal enhancing configuration including at least one of an arcuate portion of a “D” ring seal or a plurality of circumferentially extending ribs.

  • Internal combustion engine having improved cooling arrangement
    Patent number: 9127617
    Abstract: An improved cooling fluid passage configuration provides for uniformity of cooling about the entire periphery of a cylinder liner of an internal combustion engine in addition to improved cooling by increasing the flow in an upper water jacket of a split water jacket design. The cooling fluid passage configuration also provides a reduced pressure drop between a cylinder liner cooling fluid inlet and a cylinder head cooling fluid outlet when compared to conventional designs with a single head feed line, permitting use of a smaller cooling fluid pump and leading to increased efficiency of the engine.
