    摘要： There is provided a system for controlling an intake valve (53) of an internal combustion engine, including a variable valve mechanism (10) having a control shaft (12) to continuously vary a valve lift amount of the intake valve according to a rotational angle of the control shaft and an actuator (41) to drive the control shaft, and a control unit (50) that controls the actuator so as to set the control shaft to a first rotational angle position at which the valve lift amount takes a first value during an engine idling period and to a second rotational angle position at which the valve lift amount takes on a second value larger than the first value to provide a required intake quantity to start the engine during a time from the beginning of an engine speed decrease period, through an engine stop period, until the completion of a cranking period of the engine.

    摘要： A link mechanism (1) of an engine includes: an upper link (4) having a first end connected to a piston pin (3) of a piston (2); a lower link (7) connected to the upper link (4) via an upper pin (10) having a center (H), the lower link (7) being connected to a crank pin (6) of a crank shaft (5: 6, 12, 13); a control shaft (8: 14, 15) extending substantially in parallel with the crank shaft (5: 6, 12, 13), the control shaft (8: 14, 15) having a rotational center (B); and a control link (9) including: a first end swingably connected to the control shaft (8: 14, 15), and a second end connected to the lower link (7). In a process of the center (H) of the upper pin (10) moving nearer to the axial line (G) of the piston pin (3), the center (J) of the control pin (11) moves in the upward direction, thus inclining the lower link (7) and allowing the center (H) of the upper pin (10) and the center (F) of the piston pin (3) to move in the downward direction.

    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.
