摘要:
A collecting exhaust port 18 provided in a cylinder head 12 is comprised of exhaust port sections 46 extending from exhaust valve bores 35 in cylinders 14, and an exhaust collecting section 47 in which the exhaust port sections 46 are collected. The cylinder head 12 includes a protrusion 49 projecting in an arch shape outside a side wall 11 1 of a cylinder block 11. The exhaust collecting section 47 of the collecting exhaust port 18 directly faces an inner surface of a side wall 12 1 of the protrusion 49. Water jackets J 2 and J 3 for cooling the protrusion 49 are provided in upper and lower surfaces of the protrusion 49 having the collecting exhaust port 18 defined therein. The water jackets J 2 and J 3 are not provided between the side wall 12 1 of the protrusion 49 and the exhaust collecting section 47. Thus, the compact cylinder head 12 having the collecting exhaust port 18 integrally provided therein can be formed, while avoiding the complication of the structure of a core.
摘要(中):
设置在气缸盖12中的收集排气口18包括从气缸14中的排气阀孔35延伸的排气口部分46和排气口部分46收集在其中的排气收集部分47。 气缸盖12包括在气缸体11的侧壁111的外侧以拱形突出的突起49.收集排气口18的排气收集部47直接面对突起49的侧壁121的内表面。 用于冷却突起49的水套J2和J3设置在具有限定在其中的收集排气口18的突起49的上表面和下表面中。 水套J2和J3不设置在突起49的侧壁121和排气收集部47之间。因此,可以形成具有一体设置在其中的收集排气口18的紧凑型气缸盖12,同时避免了 核心的结构。
