  • CYLINDER HEAD WITH COUNTERSINK
    Publication number: 20150219006
    Abstract: A cylinder head of a static spark-ignited gas engine may include at least two exhaust ports, at least two inlet ports, at least one cylinder axis, and a bottom side. Each inlet port runs to the bottom side of the cylinder head and may have a valve seat for inlet valve. Each valve seat may have a corresponding center axis. At least one inlet port has a countersink in the border area of the bottom side. The countersink may have an offset axis shifted from the corresponding center axis. The countersink may also have a maximum radius with reference to the corresponding center axis. The maximum radius and a straight line may form an angle ?. The straight line may connect the cylinder axis with the corresponding center axis. The angle ? may fulfill the following condition: 70°<=?<=110°.
