摘要： In an internal combustion engine, comprising: an upper link (11) connected via a piston pin (21) to a piston (32) that reciprocates within a cylinder; a lower link (12) attached to a crank pin (33b) of a crankshaft (33) to be free to rotate and connected to the upper link (11) via an upper pin (22); and a control link (13) which is connected to the lower link (12) via a control pin (23) and oscillates about an oscillation central shaft (24), the following equation is established when the piston (32) is at bottom dead center
where:
θ l is a lower link attitude angle; and
α is a lower link aperture angle.
As a result, a load acting on a crank journal when the piston is at bottom dead center can be reduced.摘要翻译： 在内燃机中，包括：经由活塞销（21）连接到在气缸内往复运动的活塞（32）的上连杆（11）; 附接到曲轴（33）的曲柄销（33b）的下连杆（12），以通过上销（22）自由旋转并连接到上连杆（11）; 以及经由控制销（23）连接到所述下连杆（12）并围绕振荡中心轴（24）振荡的控制连杆（13），当所述活塞（32）处于下死区时，建立以下等式 中心cos ¸‰‰‰‰‰‰‰‰‰‰‰‰是下链路姿态角; 而±是较低的链接孔径角度。 结果，可以减少当活塞处于下止点时作用在曲柄轴颈上的负载。

摘要： A lower link of a double link type piston crank mechanism comprises a crank pin bearing housing portion that is adapted to receive a crank pin of a crankshaft and defines a first contour, an upper pin receiving bore portion that is adapted to receive an upper pin of an upper link and defines a second contour, a control pin receiving bore portion that is adapted to receive a control pin of a control link and defines a third contour, and a given portion that has therein an internally threaded bore formed in one of upper and lower half-parts of the lower link and a bored portion formed in the other of the upper and lower half-parts of the lower link, the given portion defining a fourth contour. The upper and lower half-parts are coupled by a bolt that passes through the bored portion and is engaged with the internally threaded bore. The lower link has further radially projected portions that extend radially outward beyond an imaginary minimum reference contour that is provided by connecting outer edge portions of the first, second, third and fourth contours with a continuous line.

摘要： A sliding structure for a reciprocating internal combustion engine, including sliding elements (100;104:120;124;128) relatively slidable via lubricating oil therebetween, the sliding elements including sliding surfaces (102;106:122;126;130) opposed to each other and lubricated with a laminar flow of the lubricating oil. The sliding surfaces (102;106:122;126;130) each have base surfaces (10;20) and microscopic dimples (11) or grooves (21) which are so constructed as to prevent reduction of flow resistance to the lubricating oil passing through a clearance between the sliding surfaces (102;106:122;126;130) and assure a lubricating oil film thickness required for reducing friction loss between the sliding elements (100;104:120;124;128).

摘要： A multi link type piston-crank mechanism comprises an upper link that has one end pivotally connected to a piston of the engine through a piston pin, a lower link that is pivotally connected to the other end of the upper link through an upper pin and rotatably disposed on a crank pin of a crankshaft of the engine; and a control link that has a base end part swingably held by a body of the engine and a leading end pivotally connected to the lower link through a control pin. An axis of the piston pin is offset relative to an axis of the piston in thrust and counter thrust directions. When the piston comes to BDC, a part of the piston takes a position below a lower edge of a corresponding cylinder of the engine and the upper pin is offset relative to the axis of the piston pin in the same direction as a pin offset direction in which the axis of the piston pin is offset in the thrust and counter thrust directions relative to the axis of the piston.
