摘要： A multi-link engine (10) has a piston (32) coupled to a crankshaft (33) to move inside an engine cylinder (31). A piston pin connects the piston (32) to an upper link (11), which is connected to a lower link (12) by an upper link pin. A crank pin of the crankshaft rotatably supports the lower link thereon. A control link pin (23) connects the lower link to one end of a control link (13), which is connected at another end to the engine block body by a control shaft (24). The upper link (11) has an upper link axis that forms an angle with the cylinder axis, as viewed along a crank axis direction of the crankshaft (33), such that the angle reaches a minimum when a crank angle of the engine is within a range where the bottom end of a piston skirt is positioned below a topmost part of the bottom end of the cylinder liner.

The lower link is pivotally connected to one end of a control link (13), which is connected at another end to the engine block body by a control shaft (24). The control shaft (24) is lower than a crank journal of the crankshaft, and disposed on a first side of a plane that is parallel to a cylinder center axis and that contains a center rotational axis of the crank journal. The cylinder center axis is located on a second (i.e., opposite the first side) plane. The control link (13) has a center axis that is parallel to the cylinder center axis when the piston is near top and bottom dead centers.

摘要： A piston crank mechanism has an upper link coupled to a piston by a piston pin, a lower link having a crankpin journal, wherein the crankpin journal is coupled to a crankpin of a crankshaft and is coupled to the upper link by an upper pin, and a control link is coupled to an eccentric cam of a control shaft that is supported by an engine block and coupled to a control pin boss by a control pin. The crankpin journal of the lower link is arranged and dimensioned relative to the upper pin such that a projection area defined by projecting the width of the upper pin along a direction line passing through a center of the piston pin and a center of the upper pin does not obscure an area defined by the crankpin during operation of the crankshaft as viewed in an axial direction of the crankpin.

摘要： In a crankshaft of an internal combustion engine wherein a crankthrow is shortened by the use of a multi-link mechanism, a stress concentration caused by a torsional torque in the vicinity of a pin-side opening (21) of an oil passage (20), which is open at the outer peripheral surface of a crankpin, is alleviated. The crankthrow from the axis of a main journal (2) to the axis of the crankpin (3) is set shorter than one-half of a piston stroke. The oil passage (20) is formed to supply lubricating oil to a bearing portion of the crankpin (3). The pin-side opening (21) of the oil passage (20), which is open at the outer peripheral surface of the crankpin (3), is formed in ranges other than angular ranges of 0°, 90°, 180°, and 270° with respect to a reference line (X1) extending from the axis of the main journal (2) toward the axis of the crankpin (3) in a decentering direction (X) of the crankpin.
