COMBUSTION SEAL INCLUDING CYLINDER LINER AND SHIM

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. 本申请公开了一种发动机，包括发动机缸体和安装到发动机缸体上的汽缸盖。发动机缸体包括沿轴线延伸的孔和布置在孔中并绕轴线环形地延伸的缸套。缸套包括密封表面和从密封表面径向向内布置的防火坝。防火坝沿轴线从密封表面朝向汽缸盖延伸。发动机进一步包括布置在发动机缸体和汽缸盖之间的汽缸盖垫圈。汽缸盖垫圈绕防火坝无限地延伸。发动机进一步包括位于密封表面和汽缸盖垫圈之间并且邻接密封表面和汽缸盖垫圈的垫片。垫片从防火坝径向向外布置，并绕轴线环形
