摘要： A lower link for an engine piston crank mechanism includes first and second half members joined by bolts to form a crankpin bearing portion. The first half member includes a first pin boss portion to connect the lower link with a first link which is one of an upper link connected with a piston and a control link having one end mounted swingably on the engine. The second half member includes a second pin boss portion to connect the lower link with a second link which is the other of the upper link and the control link, and an internally threaded portion into which one bolt is screwed. The second half member further includes a load transfer portion which is made greater in rigidity than the internally threaded portion.

摘要： Joining surfaces (2a, 2b) of a pair of conductive joining members (1a, 1b) to be joined to each other are caused to face each other, and while one of the joining members (1a, 1b) is slid relative to the other of the joining members (1a, 1b), a current is passed from one of the joining members (1a, 1b) to the other of the joining members (1a, 1b) so as to cause resistance heating. Abrasion, plastic flow, and material diffusion therefore occur in high surface-pressure sections of the joining surfaces (2a, 2b), and the joining surfaces (2a, 2b) are joined together while current concentration locations are varied from moment to moment.
摘要翻译：使彼此接合的一对导电性接合构件（1a，1b）的接合面（2a，2b）彼此面对，并且一个接合构件（1a，1b）相对于另一个滑动的连接部件（1a，1b）中的一个接合部件（1a，1b）中的一个通向另一个接合部件（1a，1b），从而产生电阻加热。因此，磨损，塑性流动和材料扩散发生在接合表面（2a，2b）的高表面压力部分中，并且接合表面（2a，2b）被接合在一起，同时电流集中位置随时间变化。

摘要： A multi-link piston crank mechanism for an internal combustion engine, including a crankshaft having a crank pin, and crank webs connected with each other through the crank pin. A pair of thrust surfaces are formed on the crank webs so as to be opposed in a direction of a center axis of the crank pin. A first link pivotally supported on the crank pin is coupled to a second link through a connection pin located in a space between the thrust surfaces. The connection pin is moveable about the crank pin to form a circular trace along which the thrust surfaces extend. The end surfaces of the connection pin and the thrust surfaces come into mutual contact to prevent the connection pin from falling out of the space between the thrust surfaces.

摘要： A reciprocating engine with a variable compression ratio mechanism is disclosed. A lubrication system of the engine is improved by controlling an oil pressure according to a compression ratio setting. The lubrication system includes various combinations of control valves and oil passages. The oil relief passage is opened at a high compression ratio setting applied to a low engine load range and is otherwise closed at a low compression ratio setting applied to a high engine load range.
