汽缸盖的冷却构造
摘要：
一种汽缸盖冷却构造，在该冷却构造中，多个汽缸(11A～11C)被直列地配置，在汽缸(11A～11C)上配置有进气口(13A、13B)及排气口(12A、12B)，在各汽缸(11A～11C)间的排气侧设置有汽缸盖螺栓凸台部(15)；上述汽缸盖冷却构造包括：冷却水导入部(25)，其被设置在排气口(12A、12B)的下方来将冷却水导入到汽缸盖(1)内；凸台旁冷却水流路(27A、27B)，其从冷却水导入部(25)分岔，并在汽缸盖螺栓凸台部(15)的附近延伸；汽缸间冷却水流路(23)，其在多个汽缸间(11A～11C)延伸，并且其上游端与凸台旁冷却水流路(27A、27B)合流；排气口间冷却水流路(26A)，其从冷却水导入部(25)分岔并在排气口(12A、12B)间延伸；以及断流壁(70～74)，其切断冷却水从冷却水导入部(25)经由凸台旁冷却水流路(27A、27B)的流动。
摘要（英）：

A structure for cooling a cylinder head in which a plurality of cylinders (11A-11C) are disposed in series, intake ports (13A, 13B) and exhaust ports (12A, 12B) are disposed in the cylinders (11A-11C), and head bolt boss parts (15) are provided on the exhaust side between each of the cylinders (11A-11C), wherein the cooling structure is provided with: cooling water introduction parts (25) that areprovided below the exhaust ports (12A, 12B), cooling water being introduced into a cylinder head (1) via the cooling water introduction parts (25); boss-side cooling water channels (27A, 27B) branching off from the cooling water introduction parts (25) and extending in the vicinity of the head bolt boss parts (15); inter-cylinder cooling water channels (23) extending between the plurality of cylinders (11A-11C), the upstream ends of the inter-cylinder cooling water channels (23) merging with the boss-side cooling water channels (27A, 27B); inter-exhaust-port cooling water channels (26A) branching off from the cooling water introduction parts (25) and extending between the exhaust ports (12A, 12B); and blocking walls (70-74) for blocking the flow of cooling water from the cooling water introduction parts (25) via the boss-side cooling water channels (27A, 27B).
