    • A cylinder head assembly and a method of providing an air-fuel mixture from a carburetor (510 ) to a cylinder (160) of an internal combustion engine (100) are disclosed. The cylinder head assembly includes a cylinder head (170) and a component (520) coupled to the cylinder head (170). The cylinder head (170) includes a first port (200) having a first passage (570) linking a first end (595) to an intersection, and a second passage (580) linking a second end to the intersection, where the intersection (590) includes an abrupt transition between the first and second passages (570, 580). The component (520) includes a tongue (530) that protrudes into the first passage (570) from the first end (595) to proximate the intersection, where the tongue (530) is positioned along at least a portion of an inner side of the first passage (570), and where the tongue (530) is gradually-reduced in thickness at least proximate the intersection (590).
    • 公开了一种气缸盖组件和从化油器(510)向内燃机(100)的气缸(160)提供空气 - 燃料混合物的方法。 气缸盖组件包括气缸盖(170)和联接到气缸盖(170)的部件(520)。 气缸盖(170)包括具有连接第一端(595)和交叉点的第一通道(570)的第一端口(200)和将第二端连接到交叉点的第二通道(580) 590)包括在第一和第二通道(570,580)之间的突然过渡。 部件(520)包括从第一端(595)突出到第一通道(570)中至接近交叉点的舌部(530),舌部(530)沿着至少一部分内侧 第一通道(570),并且其中舌部(530)至少在交叉点(590)附近逐渐减小。
