摘要： An engine unit includes a cylinder block of a short-skirt type which has a plurality of first partition walls and a plurality of crank journals formed on the partition walls and rotatably receiving the crankshaft. Bearing caps are fitted to the crank journals and rotatably hold the crankshaft in cooperation with the crank journals. A lower case is fixed to the cylinder block and covers the crankshaft. The lower case includes a pair of flanges abutting against the lower edges of the skirt portions, a semi-cylindrical bottom wall, and a plurality of second partition walls formed on the bottom wall to oppose the first partition walls. Each bearing cap is clamped between the first and second partition walls. The lower case is fixed to the cylinder block by means of first bolts screwed into the skirt portions through the flanges, and second bolts screwed into the crank journals through the second partition walls and bearing caps.
摘要翻译：发动机单元包括短裙型的气缸体，其具有多个第一分隔壁和形成在分隔壁上并可旋转地接收曲轴的多个曲柄轴颈。轴承盖安装到曲柄轴颈上并与曲柄轴颈配合可旋转地保持曲轴。下壳固定在气缸体上并覆盖曲轴。下壳体包括抵靠裙部的下边缘的一对凸缘，半圆柱形底壁和形成在底壁上以与第一分隔壁相对的多个第二分隔壁。每个轴承盖夹在第一和第二分隔壁之间。下壳体通过穿过凸缘螺纹拧入裙部的第一螺栓固定到气缸体上，第二螺栓通过第二分隔壁和轴承盖螺钉拧入曲柄轴颈。

摘要： A belt tensioner comprising an intermediate annular member rotatably provided around a fixed member in the form of a solid cylinder and to be secured to a stationary portion, a movable eccentric member in the form of a solid cylinder and rotatably provided around the intermediate annular member eccentrically therewith, an idler in the form of a hollow cylinder and rotatably provided around the movable eccentric member for contact with a belt, and a spring provided between the stationary portion or the fixed member and the movable eccentric member for biasing the movable eccentric member in a direction to bring the idler into pressing contact with the belt. The intermediate annular member has a cylindrical or tapered first sliding surface in contact with the fixed member and a cylindrical or tapered second sliding surface in contact with the eccentric member. One of the first and second sliding surfaces of the annular member is a high-friction sliding surface, and the other surface is a low-friction sliding surface. An oil of high viscosity is provided between the low-friction sliding surface and the surface of the fixed member or the eccentric member in contact therewith.
