    • A cylinder head (14) of an engine (10) is disclosed, the cylinder head (14) including an upper deck (30), a lower deck (32), and a sidewall (34) extending between the upper deck (30) and the lower deck (32). The lower deck (32) defines a block-engaging portion (36) and a combustion chamber flame deck (26). The combustion chamber flame deck (26) is spaced apart from the block- engaging portion (36). An engine (10) is also disclosed that includes a cylinder block (12) having a cylinder bore (16), and a piston (22) slidably positioned within the cylinder bore (16). The engine (10) also includes a cylinder head (14) having a lower deck (32) connected to the cylinder block (12), the lower deck (32) defining a block-engaging portion (36) and a combustion chamber flame deck (26). The combustion chamber flame deck (26) is spaced apart from the block-engaging portion (36) by a recess (72).
    • 公开了一种发动机(10)的气缸盖(14),气缸盖(14)包括上甲板(30),下甲板(32)和在上甲板(30)之间延伸的侧壁 和下甲板(32)。 下甲板(32)限定块接合部分(36)和燃烧室火焰甲板(26)。 燃烧室火焰甲板(26)与块接合部分(36)间隔开。 还公开了一种发动机(10),其包括具有气缸孔(16)的气缸体(12)和可滑动地定位在气缸孔(16)内的活塞(22)。 发动机(10)还包括具有连接到气缸体(12)的下甲板(32)的气缸盖(14),下甲板(32)限定块接合部分(36)和燃烧室火焰甲板 (26)。 燃烧室火焰甲板(26)通过凹部(72)与块接合部分(36)间隔开。

    • A fuel-injection system (12) for an engine (10) has a plurality of fuel- system components, including a pump (16), a fuel injector (48), and a plurality of fuel-system components connecting the pump to the fuel injector. A portion of the fuel-injection system from the pump to the fuel injector may include a first joint (70) mating a first pair of the fuel-system components, a second joint mating (72) a second pair of the fuel-system components, and a third joint (74) mating a third pair of the fuel-system components. Each of the first joint, the second joint, and the third joint may include a curved surface (40) and a corresponding seat (42) that are mated to one another and that provide a substantially fluid-tight seal and allow variation in the angular relationship between the associated pair of fuel-system components.
    • 用于发动机(10)的燃料喷射系统(12)具有多个燃料系统部件,包括泵(16),燃料喷射器(48)和将泵连接到燃料喷射器的多个燃料系统部件 喷油器。 从泵到燃料喷射器的燃料喷射系统的一部分可以包括与第一对燃料系统部件配合的第一接头(70),第二接头配合(72),第二对燃料系统部件 以及与第三对燃料系统部件配合的第三接头(74)。 第一关节,第二关节和第三关节中的每一个可以包括彼此配合的弯曲表面(40)和相应的座(42),并且提供基本上流体密封的密封并且允许角度 相关联的燃料系统组件之间的关系。
