摘要： 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 (3a) and an internal wall region (3b) 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 (3a), 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 (4a) of the valve seat ring (4), whereby the internal surface (4a) of the valve seat ring (4) extends beyond said projection (11).
