    • The invention relates to a cylinder head ( 1 ) for an internal combustion engine with at least one inlet channel ( 3 ), which generates a swirling flow (S) in the combustion chamber ( 2 ), preferably curved in the direction of the swirling flow (S) with an external wall region ( 3 a) and an internal wall region ( 3 b) relative to the swirling flow (S). A valve seat ring ( 4 ) is arranged in the region of the opening ( 9 ) of the inlet channel ( 3 ) into the combustion chamber ( 2 ). According to the invention, a strong swirling flow (S) without significant reduction of the flow cross-section of the inlet channel ( 3 ) may be achieved whilst keeping the mechanical loading on the cylinder head to a minimum, whereby the external wall region ( 3 a), in the region of the valve seat ring ( 4 ), is at least partly formed by a projection ( 11 ) of the cylinder head ( 1 ) within an internal surface ( 4 a) of the valve seat ring ( 4 ), whereby the internal surface ( 4 a) of the valve seat ring ( 4 ) extends beyond said projection ( 11 ).
    • 用于内燃机的汽缸盖(1)技术领域本发明涉及一种用于内燃机的汽缸盖(1),其具有至少一个在燃烧室(2)中产生涡流(S)的入口通道(3),所述入口通道优选地在涡流方向 (S)相对于旋流(S)具有外壁区域(3a)和内壁区域(3b)。 在入口通道(3)的通向燃烧室(2)的开口(9)的区域中布置有阀座环(4)。 根据本发明,可以在不明显减小入口通道(3)的流动横截面的情况下实现强旋流(S),同时将汽缸盖上的机械负载保持为最小,由此外壁区域 在阀座环(4)的区域中,至少部分地由气缸盖(1)的突起(11)形成在阀座环(4)的内表面(4a)内, 由此阀座环(4)的内表面(4a)延伸超过所述突出部(11)。
