Zusammenfassung:A cylinder head includes a cylinder head casting having four gas exchange openings formed in a fire deck. The bolt hole and the glow plug hole extend through the cylinder head casting between the upper surface and the lower surface. The four gas exchange openings are arranged circumferentially around the injector bore central axis at twelve o'clock, three o'clock, six o'clock, and nine o'clock positions. The bolt hole is angularly positioned between a twelve o'clock position and a three o'clock position, and the glow plug hole is angularly positioned between a three o'clock position and a six o'clock position. 一种气缸盖包括气缸盖铸件,所述气缸盖铸件具有形成在防火甲板中的四个气体交换开口。螺栓孔和电热塞孔在上表面与下表面之间延伸通过气缸盖铸件。四个气体交换开口周向地围绕喷射器孔中心轴线布置在十二点钟、三点钟、六点钟和九点钟位置。螺栓孔成角度地定位在十二点钟位置与三点钟位置之间,并且电热塞孔成角度地定位在三点钟位置与六点钟位置之间。
