A cylinder head assembly (20) includes a cylinder head casting (26), and an injector sleeve (60) within an injector bore (42) in the cylinder head casting (26). The injector sleeve (60) includes a first sleeve end (68) and an injector clamping surface (76) formed by a sleeve inner surface (64) adjacent to a cylindrical second sleeve end (70). The injector sleeve (60) further includes a sleeve clamping surface (80) in contact with an upwardly facing intermediate deck surface (38) of the cylinder head casting (26), and a reaction wall (74) extending between the injector clamping surface and the sleeve clamping surface (80) to transfer an injector clamping load to the upwardly facing intermediate deck surface (38). 一种气缸盖组件(20)包括气缸盖铸件(26)，以及在气缸盖铸件(26)中的喷射器孔(42)内的喷射器套筒(60)。喷射器套筒(60)包括第一套筒端(68)，以及由邻近于圆柱形第二套筒端(70)的套筒内表面(64)形成的喷射器夹持表面(76)。喷射器套筒(60)还包括套筒夹持表面(80)和反作用壁(74)，所述套筒夹持表面与气缸盖铸件(26)的面向上的中间甲板表面(38)接触，所述反作用壁在喷射器夹持表面与套筒夹持表面(80)之间延伸以将喷射器夹持负荷传递到面向上的中间甲板表面(38)。
