摘要： This invention relates to a cooling structure for cooling a cylinder liner by circulating coolant in a water jacket formed along an outer periphery of the cylinder liner. This cooling structure includes an annular first water reservoir for temporarily storing coolant. This first water reservoir allows the coolant to uniformly flow circumferentially of the cylinder liner. The cooling structure also includes a plurality of coolant passages provided radially for connecting the first water reservoir to the water jacket. The coolant is caused to strike a part of a wall defining the water jacket substantially vertically from the radial coolant passages, thereby to generate turbulent flow in the coolant to efficiently cool the cylinder liner.

摘要： No-load valve lift correction curves of opening and closing cams are set by offsetting no-load curve sections of basic valve lift curves of the cams in such directions as to increase a clearance between the curves, and they are connected with remaining sections of the curves to provide normal valve lift curves of the cams. Cam profiles of the cams are set on the basis of such normal valve lift curves. The cam profiles are set so that an ultimate speed difference between jumping and landing speeds of a follower on an ultimate valve speed curve determined from ultimate valve lift curves, having first and second shift sections where the follower shifts from the opening cam to the closing cam and from the closing cam to the opening cam, is smaller than a basic speed difference between jumping and landing speeds on a basic valve speed curve.
摘要翻译：打开和关闭凸轮的空载气门升程校正曲线是通过偏移凸轮的基本气门升程曲线的空载曲线段来设定，以增加曲线之间的间隙，并与它们的剩余部分相连曲线提供凸轮的正常气门升程曲线。凸轮的凸轮轮廓基于这种正常的气门升程曲线设定。凸轮轮廓被设置成使得从极限气门升程曲线确定的极限阀速度曲线上从动件的跳跃和着陆速度之间的极限速度差异具有第一和第二换档部分，其中从动件从打开凸轮移动到关闭凸轮并且从关闭凸轮到打开凸轮，小于基本阀速度曲线上的跳跃和着陆速度之间的基本速度差。
