    • A four-cycle air-oil cooled engine includes a cylinder head having a spark plug mounting hole formed therein, and a ring-like groove formed therein and surrounding the spark plug mounting hole. The cylinder head is formed with first and second co-planar sealing surfaces, disposed on a plane perpendicular to an axis of the spark plug mounting hole, and having an opening end of the ring-like groove disposed therebetween. The ring-like groove defines an oil jacket around the periphery of the spark plug mounting hole. A cover member having a flat surface opposed to the first and second flat sealing surfaces of the cylinder head is secured to the cylinder head such that a single gasket is interposed between the first and second sealing surfaces and the flat surface of the cover member.
    • 四冲程空气 - 油冷却发动机包括其中形成有火花塞安装孔的气缸盖和形成在其中并围绕火花塞安装孔的环形槽。 气缸盖形成有第一和第二共面密封表面,其设置在垂直于火花塞安装孔的轴线的平面上,并且其间设置有环状槽的开口端。 环形槽围绕火花塞安装孔的周边限定油套。 具有与气缸盖的第一和第二平坦密封面相对的平坦表面的盖构件固定到气缸盖,使得单个垫圈插入在第一和第二密封表面与盖构件的平坦表面之间。
