Abstract
The present application includes a cylinder liner for an internal combustion engine. This cylinder liner includes a main body portion forming a cylinder bore, with a spot face configured to interface with a first portion of a cylinder head gasket. A flange extends outward from the main body portion, with an outer face configured to interface with a second portion of the cylinder head gasket. The spot face is recessed below the outer face, making the outer face proud of the spot face. The cylinder head gasket is interposed between substantially the entirety of the spot face and the outer face and the cylinder head, forming a seal.
Claims20
A cylinder liner for an internal combustion engine, comprising:
- a main body portion forming a cylinder bore of the internal combustion engine, wherein the main body portion has a spot face that is configured to interface with a first portion of a cylinder head gasket;
- a flange extending outward from the main body portion, wherein the flange includes a outer face that is configured to interface with a second portion of the cylinder head gasket;
- wherein the spot face is recessed a distance below the outer face such that the outer face is proud of the spot face.
An internal combustion engine comprising:
- a cylinder head;
- an engine block;
- a cylinder liner received at least partially within the engine block, wherein the cylinder liner includes a main body portion that forms a cylinder bore configured to receive a piston therein and a flange extending outward from the main body portion, wherein the main body portion has a spot face and the flange has an outer face, and wherein the spot face is recessed a distance below the outer face such that the outer face is proud of the spot face;
- and
- a cylinder head gasket arranged between substantially an entirety of the spot face and the cylinder head and arranged between substantially an entirety of the outer face and the cylinder head, wherein the cylinder head gasket forms a seal with the spot face and the outer face.
A method of sealing a cylinder bore of an internal combustion engine, comprising:
- providing a cylinder head and a cylinder liner that defines the cylinder bore, wherein the cylinder liner includes a spot face extending from the cylinder liner and the cylinder liner includes an outer face radially outward of the spot face, and wherein the spot face is recessed a distance below the outer face such that the outer face is proud of the spot face with respect to the cylinder head;
- interposing a cylinder head gasket between the cylinder liner and the cylinder head to cover substantially all of the spot face and substantially all of the outer face;
- and
- compressing the cylinder head gasket against the spot face and the outer face.
