    • An internal combustion engine (1) including variable compression ratio comprises a crankcase (2) and a crankshaft (3) including a crankshaft axis (4). The crankshaft (3) has at least a central main portion (5), a crankpin (6) and a crankshaft web (7) located between the central main portion (5) and the crankpin (6). The crankshaft (3) is supported by the crankcase (2) and rotatable with respect thereto about the crankshaft axis (4). The engine (1) comprises at least a connecting rod (11) including a big end (10) and a small end (12), a piston (13) which is rotatably connected to the small end (12) and a crank member (8) that is rotatably mounted on the crankpin (6), and comprises at least a bearing portion (9) which is eccentrically disposed with respect to the crankpin (6). The bearing portion (9) has an outer circumferential wall which bears the big end (10) of the connecting rod (11) such that the connecting rod (11) is rotatably mounted on the bearing portion (9) of the crank member (8) via the big end (10). The engine (1) comprises a driving mechanism for driving the crank member (8) at half speed of the crankshaft (3) as seen from the crankcase (2). The driving mechanism comprises a control member (17) for varying the compression ratio, which is rotatable with respect to the crankcase (2) and drivably coupled to the crank member (8), but has a fixed position with respect to the crankcase (2) under operating conditions at fixed compression ratio. The rotational position of the control member (17) with respect to the crankcase (2) is adjustable by means of a hydraulic actuator (18), which comprises a hydraulic piston (20) that is drivably connected to the control member (17), a working chamber (21), a pump (23) and an oil supply line (25) through which the pump (23) and the working chamber (21) communicate.

    • An improved reciprocating internal combustion engine converts a larger percentage (than a conventional engine) of the linear force exerted by the piston into rotation of the crankshaft when the combustion pressures are at maximum, high or intermediate levels. This increased conversion results in more power per cycle, when compared to conventional engines of comparable size. The improved engine includes an engine block, a cylinder within the engine block, a piston slidably positioned within the cylinder for a reciprocating motion, a crankshaft, a connecting rod and a torque arm. One side of the connecting rod is pivotally mounted to the piston and on the other side to the torque arm. The torque arm is also operatively rigidly connected to a template that is mounted to the engine block. The template guides the movement of the torque arm along a predetermined path. The template is configured to position the torque arm at an angle with respect to the radius of the crankshaft at the pivot point such that the combined value of vectors that contribute to turning the crankshaft are significantly larger than that of the turning vectors in a conventional engine, when the combustion pressure in the cylinder is at the maximum high or intermediate levels.

    • When a stopper portion is brought into abutment against body high-compression-ratio side stopper portion (35), when viewed in the control shaft axial direction, it is configured that the distance between body high-compression-ratio side stopper surface (42) and control-shaft high-compression-ratio side stopper surface (40) becomes relatively longer as being closer to the control shaft rotation center. Similarly, when a stopper portion is brought into abutment against body low-compression-ratio side stopper portion, when viewed in the control shaft axial direction, the distance between body low-compression-ratio side stopper surface and control-shaft, low-compression-ratio side stopper surface becomes relatively longer as being closer to the control shaft rotation center.
    • 当从控制轴的轴向观察止挡部抵接于主体高压缩比侧止挡部35时,主体高压缩比侧止挡面42与主体高压缩比侧止挡面42之间的间隔变窄, 控制轴高压缩比侧止动面40越靠近控制轴旋转中心越长。 同样地,当止动部与主体低压缩比侧止动部抵接时,从控制轴轴向观察时,主体低压缩比侧止动面与控制轴之间的距离,低压缩率 随着接近控制轴旋转中心,截止侧止动面变得相对较长。

    • A fluid flow machine includes a casing including a cylinder and a crankshaft support. A piston is slidably disposed in the cylinder for reciprocating along an axis of the cylinder. A crankshaft includes a main bearing journal rotationally supported in the crankshaft support, a crankpin radially offset from an axis of the main bearing journal and a crank web connecting the main bearing journal and the crankpin. A multi-linkage connecting rod mechanism is connected between the piston and crankpin and includes a connecting rod, a first hinge link and a crankpin link pivotally connected to each other. A force transfer mechanism connects the multi-linkage connecting rod mechanism to the casing for transferring a vertical piston force into a horizontal crankpin force.
