    • The upper retainer for retaining an upper portion of a valve spring is shaped like a perforated spinning top and is axially dividable into two identical elements which are coaxially disposed about the upper portion of the valve stem when assuming its operative condition. The retainer has, when assuming the operative position, a configuration which comprises a collar portion which is sized to be coaxially disposed within an upper portion of the valve spring, an annular flange portion extending radially outward from the upper end of the collar portion and engaging with the upper end of the valve spring, and means for achieving a spline connection between the central portion of the retainer and the upper portion of the valve stem.

    • A piston ring for an internal combustion engine having a piston and a cylinder of an elliptical or oblong circular cross-sectional shape is divided into two or more segments which are connected end to end in a ring. Each of the end-to-end joints between the neighboring segments is so designed as to provide an adequate surface pressure of the piston ring against the cylinder wall when installed in a cylinder. In one embodiment, the piston ring comprises two arc segments each of which has two inward projections projecting from both ends of the segment, respectively. In the installed state, the two inward projections of one arc segment abut against the inward projections of the other segment, respectively, in such a manner that an abutting pair of the inward projections at each joint produce a force which tends to increase a gap clearance between the ends of the segments. In another embodiment, the piston ring comprises two arc segments and two rectilinear segments disposed, in parallel with each other, between the two arc segments to form an oblong circular ring shape. In the installed state, both ends of each arc segment is compressed between the two rectilinear segments so that the two arc segments push the rectilinear segments outwardly so as to increase the distance between the rectilinear segments.
    • 具有活塞和椭圆形或长圆形圆形横截面形状的圆筒的内燃机活塞环被分成两个或多个在环中端对端连接的部分。 相邻节段之间的每个端对端接头被设计成当安装在气缸中时提供活塞环抵靠气缸壁的足够的表面压力。 在一个实施例中,活塞环包括两个弧段,每个弧段分别具有从段的两端突出的两个向内突出部。 在安装状态下,一个弧形部分的两个向内的突出部分别分别抵靠另一个部分的向内的突出部,使得每个关节处的向内突出部的邻接对产生趋于增加间隙的力 在段的末端之间。 在另一个实施例中,活塞环包括在两个弧段之间彼此平行设置的两个弧段和两个直线段,以形成长圆形环形。 在安装状态下,每个弧段的两端在两个直线段之间被压缩,使得两个弧段向外推直线段以增加直线段之间的距离。

    • A bearing beam structure is secured to a cylinder block of an internal combustion engine and includes a plurality of main bearing cap sections each of which associates with each bearing section of the cylinder block so as to rotatably support a crankshaft. At least a beam section is rigidly connected to the lower end portion of each bearing cap section to securely connect all the bearing cap sections with each other. Additionally, first and second side wall sections are rigidly connected to the opposite side portions of each bearing cap section to securely connect all the bearing cap sections with each other. Accordingly, the bearing beam structure is improved in rigidity to suppress various vibrations of the cylinder block, thereby effectively achieving total engine noise reduction.
    • 轴承梁结构被固定到内燃机的气缸体,并且包括多个主轴承盖部分,每个主轴承盖部分与气缸体的每个轴承部分相关联,以便可旋转地支撑曲轴。 至少梁部分刚性地连接到每个轴承盖部分的下端部分,以将所有轴承盖部分彼此牢固地连接。 此外,第一和第二侧壁部分刚性连接到每个轴承盖部分的相对侧部分,以将所有轴承盖部分彼此牢固地连接。 因此,提高了轴承梁结构的刚性,以抑制气缸体的各种振动,从而有效地实现发动机总体噪声降低。

    • A cylinder block comprises an upper block deck disposed along whole the periphery of a cylinder-barrel section to securely connect the cylinder-barrel section with a water jacket outer wall section. The upper block deck is located below the top of the cylinder block and so positioned that its center lies at the level of an uppermost part of the skirt section of a piston which is at a range from TDC to 30 degrees relative to TDC. Additionally, upper and lower water jackets are formed at the upper and lower sides of the upper block deck, and communicate with each other through water holes formed through the upper block deck. By virtue of the thus located upper block deck, the wall of the cylinder-barrel section is effectively prevented from vibration due to piston slap, thereby greatly reducing piston slap noise emitted from the cylinder block.
    • 气缸体包括沿缸筒部分的整个周边设置的上部板甲板,以将缸筒部分与水套外壁部分牢固连接。 上部块甲板位于气缸体的顶部下方,并且定位成其中心位于活塞的裙部的最上部的水平面,该活塞的裙部相对于TDC在TDC至30度的范围内。 此外,上,下水套形成在上块板的上侧和下侧,并通过形成在上块板上的水孔相互连通。 由于这样定位的上部挡板甲板,缸筒部分的壁被有效地防止由于活塞撞击而产生的振动,从而大大降低了从气缸体发出的活塞撞击噪声。
