Embodiment Construction

[0034] Referring to the drawings, wherein like numerals refer to like components throughout the several views, an engine 10 is generally shown. Engine 10 includes an engine block 12 and a cylinder head 14 mounted to engine block 12 . The engine block 12 includes a bore 16 extending along an axis A and a cylinder liner 18 disposed in the bore 16 and extending annularly about the axis A. As shown in FIG. The cylinder liner 18 includes a sealing surface 20 and a fire dam 22 disposed radially inward from the sealing surface 20 . Fire dam 22 extends along axis A from sealing surface 20 towards cylinder head 14 . Engine 10 further includes a cylinder head gasket 24 disposed between engine block 12 and cylinder head 14 . The cylinder head gasket 24 extends infinitely around the fire dam 22 . Engine 10 further includes a gasket 26 positioned between and abutting sealing surface 20 and cylinder head gasket 24 . The gasket 26 is arranged radially outwardly from the fire dam 22 and e...

Abstract

The invention discloses an engine, including an engine block and a cylinder head mounted to the engine block. The engine block includes a bore elongated along an axis and a liner disposed in the bore and extending annularly about the axis. The liner includes a seal surface and a fire dam disposed radially inward from the seal surface. The fire dam extends along the axis from the seal surface towards the cylinder head. The engine further includes a head gasket disposed between the engine block and the cylinder head. The head gasket extends endlessly around the fire dam. The engine further includes a shim seated between the seal surface and the head gasket and abutting the seal surface and the head gasket. The shim is disposed radially outward from the fire dam and extending annularly about the axis.

Description

technical field [0001] This application relates to the field of engines. Background technique [0002] An internal combustion engine includes a cylinder head. The cylinder head is removable from the engine block to allow access to internal components for assembly and repair. A cylinder head gasket is disposed between the cylinder head and the engine block and prevents gas and / or fluid leakage between the cylinder head and the engine block. The cylinder head may be secured to the engine block by fasteners such as bolts. These fasteners extend through the cylinder head and threadably engage holes in the engine block to retain the gasket between the cylinder head and the engine block. [0003] The engine block includes cylinders that house pistons of the engine. In certain types of engines, such as diesel engines, the engine block includes cylinder liners. The cylinder liners are disposed in corresponding bores of the engine block, eg, by an interference fit between the li...
