    • In one embodiment of the present invention, a cooling water path that extends in the direction of a row of cylinders is provided between left and right banks. A communication port that communicates with a discharge port of the water pump is provided at a position on the front side between the left and right banks in the direction of the row of cylinders, and first to third and fourth to sixth introduction ports that introduce cooling water to a water jacket of the left and right banks of the cylinder block from the rear side in the direction of the row of cylinders, are formed in the cooling water path. Also, among first to fourth outlet ports 31a to 31d of a cylinder gasket 3R that correspond to each cylinder, a second outlet port 31b that is second from the front side in the direction of the row of cylinders and corresponds to a third and fourth cylinder #3 and #4 is formed with a large opening area such that an outflow volume of cooling water to left and right cylinder heads is greater for the second outlet port 31b than for third and fourth outlet ports 31c and 31d that are further to the rear in the direction of the row of cylinders and correspond to fifth to eighth cylinders #5 to #8.
    • 在本发明的一个实施例中,在一列气缸的方向上延伸的冷却水通道设置在左右两侧之间。 与水泵的排出口连通的连通口设置在排列方向上的左右侧的前侧的位置和引导冷却的第一至第三至第四至第六引入口 在冷却水路径中形成有从筒体的方向的后侧向气缸体的左右两侧的水套的水。 此外,在与气缸相对应的气缸垫圈​​3R的第一至第四出口31a至31d中,第二出口端口31b是从行的方向的前侧开始的第二出口端口31b,并且对应于第三和第四气缸 #3和#4形成有大的开口面积,使得第二出口31b的左右气缸盖的冷却水的流出量大于进一步向后的第三和第四出口31c和31d 在行的方向上,对应于第五至第八气缸#5至#8。
