    摘要： In a lash adjuster (A) of a valve gear which employs a serration-shaped thread mechanism, the formation of tribochemical reactive film is suppressed by using as the materials for its adjuster screw (15) and nut member (13) or the materials for their thread surfaces such materials that even if FM oil (friction modifier oil: motor oil containing organic molybdenum) is used, the friction coefficient will not extremely fall. The nut member is provided on the underside of an end plate (12) of a lifter body (11). The adjuster screw (15) is threadedly engaged in a threaded hole (14) of the nut member (13). The adjuster screw is biased by a return spring (16). The female threads of the threaded hole and the male threads of the adjuster screw are serration shaped. One or both of the nut member and the adjuster screw, or the pressured thread surfaces of one or both of them are formed of a material that will not react with oil additives of FM oil to suppress the formation of tribochemical reactive film, thereby stabilizing the operation of the lash adjuster.

    摘要： A toroidal-type continuously variable transmission (CVT), including rolling elements having traction surfaces cooperating with each other to transmit a power between the rolling elements via a traction oil film formed between the traction surfaces. The traction surfaces have the microstructure that is defined with respect to a thickness of the traction oil film formed when the temperature of the traction portion of the traction surface is high, to thereby exhibit high traction coefficient even in the high-temperature operating condition.

    摘要： In an internal combustion engine, a piston (8) reciprocating in a cylinder (19) and a crankshaft (1) are linked with each other by a piston-crank linking mechanism (4, 5, 10). The crankshaft (1) includes a counterweight (15). When the piston (8) is located in the proximity of a bottom dead center, an outermost portion of the counterweight (15) crosses an imaginary extension line extended from a piston pin (7) in an axial direction of the piston pin (7).

    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.

    摘要： In an internal combustion engine of variable compression ratio type, a piston control mechanism is employed which comprises a lower link rotatably disposed on a crank pin of a crankshaft of the engine, an upper link having one end pivotally connected to the lower link and the other end pivotally connected to a piston of the engine, a control link having one end pivotally connected to the lower link; and a position changing mechanism which changes a supporting axis about which the other end of the control link turns. When the piston comes up to a top dead center, a compression load is applied to the control link in an axial direction of the control link in accordance with an upward inertial load of the piston.
