摘要： A variable compression ratio mechanism for a reciprocating engine includes a connecting rod split into upper and lower connecting rod portions linked to each other through a first connecting pin. A rockable arm is oscillatingly linked at one end to the lower connecting rod portion through a second connecting pin. A control mechanism shifts the center of oscillating motion of the rockable arm to vary a compression ratio of the engine. A piston stroke is set to be greater than two times a crank radius of a crank, irrespective of variations in the compression ratio. A linkage is dimensioned and laid out, so that its crankpin load is less than a crankpin load produced by a linkage that the crankpin is located on a perpendicular line at substantially the midpoint of a line segment between and including the centers of the first and second connecting pins.

摘要： A paired counterweights of a crankshaft have projected inner surfaces which protrude toward each other defining a given space therebetween. A plurality of links are arranged to convert a reciprocating motion of a piston to a rotational motion of the crankshaft. One of the links is pivotally connected to other links through link connecting portions and swingably disposed on a crank pin of the crankshaft so that upon rotation of the crankshaft, a peripheral portion of the link passes through the given space. At least one of the link connecting portions is placed within an imaginary circle which would be described by a radially innermost part of the projected inner surfaces of the paired counterweights when the paired counterweights turn about an axis of the crank pin.

摘要： A supercharged internal combustion engine is provided with a double-link type piston crank mechanism connecting between a piston and a crankshaft. The piston crank mechanism causes the piston to move at a speed which is smaller around a top dead center (TDC) and larger around a bottom dead center (BDC) as compared with respective corresponding piston speeds attained by a comparable single-link type piston crank mechanism. The double-link type piston crank mechanism variably controls a compression ratio by varying an angular position of one of links constituting the piston crank mechanism.

摘要： An internal combustion engine is constructed to include a variable compression ratio mechanism. The mechanism has the following structure. An upper link has one end pivotally connected to a piston pin of a piston of the engine. A lower link is pivotally disposed on a crank pin of a crankshaft of the engine and has one part pivotally connected to the other end of the upper link. A control shaft extends substantially in parallel with the crankshaft. A control link has an end pivotally connected to the other part of the lower link. The other end of the control link is connected to the control shaft through an eccentric bearing structure, so that rotation of the control shaft about its axis induces a pivoting of the lower link about the crank pin varying the stroke of the piston.

摘要： A variable compression-ratio, multiple-link type reciprocating internal combustion engine has at least three links, namely an upper link, a lower link and a third link, for each engine cylinder. The upper link is connected to a piston pin, the lower link connects the upper link to a crank pin, and the third link is pivoted at one end to a body of the engine and connected at its other end to either of the upper and lower links to permit oscillating motion of the third link on the engine body. The upper link, the lower link, and the third link are dimensioned and laid out, so that the amplitude of a second-order vibration component of a vibrating system of reciprocating motion of the piston, synchronizing rotary motion of the crankshaft, is suppressed and reduced to below a predetermined threshold value, while realizing the same piston stroke and engine-cylinder height as a single-link type reciprocating internal combustion engine in which a piston pin and a crank pin are connected to each other by a single link.
