    • PROBLEM TO BE SOLVED: To provide a water-cooled engine in which a cooling-water-outflow part for letting out the water from a cooling jacket is placed in a cylinder head without interfering with a valve train chamber, while maintainability of a spark plug is ensured, and the engine can be miniaturized around the cylinder head. SOLUTION: A recess 158 is formed on a wall 33a, 34a forming a valve-train-chamber opposing to the other part of a camshaft 141 partly facing a chain chamber 151. The spark plug 159 with the rear end placed in the recess 158 is attached slantingly to the cylinder head 33 in the manner so as to go away from the chain chamber 151, as it goes away from a combustion chamber 117. A cooling-water outflow pipe 161 is placed in the cylinder head 33 nearly parallel with the axis C of the cylinder to the outside of the valve-chamber-forming walls 33a, 34a in the manner so as to be shifted to either side of an intake valve and an exhaust valve from the recess 158.

    • 要解决的问题:提供一种水冷发动机,其中将冷却套管中的水排出的冷却水 - 流出部分放置在气缸盖中,而不会干扰气门机构室,同时维持 确保火花塞,并且发动机可以围绕气缸盖小型化。 解决方案:在形成与部分面向链条室151的凸轮轴141的另一部分相对的气门室的壁33a,34a上形成有凹部158.后端放置在 凹部158以与离开燃烧室117的方式远离链式室151的方式倾斜地安装到气缸盖33.冷却水流出管161放置在气缸盖33中几乎平行 将气缸的轴线C以阀室形成壁33a,34a的外侧的方式从凹部158移动到进气门和排气阀的任一侧。版权所有: (C)2005,JPO&NCIPI
