Embodiment Construction

[0028] As mentioned above, seals are often provided between the respective cylinder liners and the cylinder block in order to keep the liner coolant provided between the cylinder liners and the cylinder block to pass between the cylinder liners and the cylinder block, And mixed with combustion gas. These seals are typically formed from an elastomeric material that may degrade over time to the point that it requires repair of one or more bushings disposed at the interface between the cylinder liner and cylinder block. Seals are replaced. In this case, the corresponding cylinder liner is removed, the worn or degraded liner seal is removed from the circumferential groove formed in the outer surface of the cylinder liner, and a new liner seal is positioned at each corresponding slots, and the cylinder liners are moved back and positioned in corresponding cylinder bores of the cylinder block. The inventors of the present invention point out that such a process is cumbersome and i...

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.

Description

technical field [0001] The present invention generally relates to a cylinder liner seal for an internal combustion engine. More specifically, the invention relates to a press-fit and easily retained cylinder liner seal for preventing coolant from passing through the junction between the cylinder block and the cylinder liner, and also relates to setting and replacing method of this seal. Background of the invention [0002] The inclusion of replaceable cylinder liners in the design of internal combustion engines provides numerous advantages to the manufacture of such engines and to their users. In addition to its obvious advantage of replacing the cylinder liner during an overhaul of the engine without replacing the entire cylinder block, the cylinder liner eliminates the possibility of cylinder liners being improperly machined or damaged during manufacture or use. And the necessity of scrapping the entire cylinder block. Despite this and other advantages, a number of prob...
