    • The present disclosure refers to a cylinder head (1) of a static spark-ignited gas engine. The cylinder head may comprise at least two exhaust ports (7.1, 7.1') and at least two inlet ports (1.1, 1. 1') which run to a bottom side (1.3) of the cylinder head (1). The cylinder head (1) have at least one cylinder axis (9) and each inlet port (1.1, 1. 1') may have a valve seat (2, 2') for inlet valves. Each of said valve seats (2, 2') may have a center axis (2.1, 2. 1'), with at least one inlet port (1.1, 1. 1') having a countersink (3, 3') in the border area of the bottom side (1.3) of the cylinder head (1). The countersink (3, 3') may have an offset axis (3.1, 3.1') shifted from said center axis (2.1, 2. 1') effecting a swirl flow. A radius RF, RF' of said countersink (3, 3') may have a point M, M', said point M, M' being a radial maximum with reference to the center axis (2.1, 2. 1'). The radius RF, RF' and a straight line MG, MG' may include an angle φ. The straight line MG, MG' may connect the cylinder axis (9) with the center axis (2.1, 2. 1') of said valve seat (2, 2') of said inlet port (1.1, 1. 1'). The angle φ may fulfill the following condition: 70°
    • 本发明涉及一种静电火花点燃气体发动机的气缸盖(1)。 气缸盖可以包括至少两个排气口(7.1,7.1')和至少两个进入气缸盖(1)的底侧(1.3,1.1')的入口端口(1.1,1.1')。 气缸盖(1)具有至少一个气缸轴线(9),并且每个入口端口(1.1,1.1')可具有用于入口阀的阀座(2,2')。 每个所述阀座(2,2')可以具有中心轴线(2.1,2.1'),其中至少一个入口端口(1.1,1.1')在所述中心轴线 气缸盖(1)的底面(1.3)的边界区域。 埋头孔(3,3')可能具有从所述中心轴线(2.1,2.1')偏移的偏移轴线(3.1,3.1'),从而产生涡流。 所述埋头孔(3,3')的半径RF,RF'可以具有点M,M',所述点M,M'相对于中心轴线(2.1,2.1')是径向最大值。 半径RF,RF'和直线MG,MG'可以包括角度&phgr。 直线MG,MG'可以将气缸轴线(9)与所述入口(1.1,1.1')的所述阀座(2,2')的中心轴线(2.1,2.1')连接。 角&phgr 可以满足以下条件:70°<=&phis; <= 110°。 本公开还涉及一种制造本文公开的类型的气缸盖(1)的方法和操作静态火花点火燃气发动机的方法。

    • A spark plug (5; 5') may comprise a shell (20; 120) surrounding a lower part of an insulator (15; 1 15). The shell (20; 120) may be provided with a tool engaging portion (25; 125), a seal face (30; 130) configured to contact a corresponding seal of a cylinder head (200) of an internal combustion engine, a cylinder engaging threaded portion (40; 140) having a thread diameter (D) configured to screw the spark plug (5; 5') in a threaded bore (210) of the cylinder head (200), and an intermediate portion (35; 135) extending between the shoulder (30; 130) and the cylinder engaging threaded portion (40; 140). The intermediate portion (35; 135) may have a length (L 1 ), wherein: 0.20 1 /D
    • 火花塞(5; 5')可以包括围绕绝缘体(15; 115)的下部的壳体(20; 120)。 壳体(20; 120)可以设置有工具接合部分(25; 125),密封面(30; 130),其构造成接触内燃机的气缸盖(200)的对应密封件,气缸 具有螺纹直径(D)的接合螺纹部分(40; 140),其构造成将火花塞(5; 5')拧入气缸盖(200)的螺纹孔(210)中,以及中间部分 )在所述肩部(30; 130)和所述圆筒接合螺纹部分(40; 140)之间延伸。 中间部分(35; 135)可以具有长度(L1),其中:0.20 <= L1 / D <= 0.80,而Li是长度,D是螺纹直径。 本公开还涉及一种具有用于这种火花塞(5; 5')的钻孔(210)的气缸盖(200),并且其涉及适配的火花塞衬套(300)。
