摘要： A piston crank mechanism of an internal combustion engine includes an upper link connected to a piston, a lower link connected to both the upper link and a crankpin, and a control link through which the lower link is linked to an eccentric cam of a control shaft to restrict the degree of freedom of the lower link. By varying the angular position of the eccentric cam with respect to the control-shaft axis, the center of oscillating motion of the control link varies, thus varying a compression ratio. The center of gravity of the lower link, determined by an equivalent inertia weight obtained by adding weights of connecting pins and weights of the upper-link boss-shaped end and the control-link boss-shaped end connected to the lower link via the respective connecting pins to the lower-link self-weight, is situated closer to the center of the crankpin.

摘要： A variable compression ratio mechanism for a reciprocating engine includes upper and lower links linking a piston pin to a crankpin, an eccentric cam equipped control shaft and a control link cooperating with each other to vary the attitude of the upper and lower links. A control-shaft actuator is provided to vary a compression ratio. The actuator includes a reciprocating block slider linked at a front end to the control shaft, and a rotary member being in meshed-engagement with the rear end of the slider by a meshing pair of screw-threaded portions. A hydraulic modulator has a hydraulic pressure chamber facing the rear end face of the slider, so that working-fluid pressure in the pressure chamber forces the slider in the same axial direction as the direction of action of reciprocating load acting on the slider owing to combustion load.

摘要： A four-stroke internal combustion engine includes variable geometric compression ratio, electrically operated inlet valves and a device for supplying a homogeneous fuel/air mixture to the engine cylinders. The inlet valves and the compression ratio are controlled by a control unit, so that the fuel/air mixture, within a lower engine rpm range, is compressed to self-ignition.

摘要： An engine has a plurality of combustion cylinders with a first piston reciprocably mounted in each of the combustion cylinders in the conventional manner. The engine head has, in communication with each of the combustion cylinders, a cylindrical recess containing a reciprocably mounted second piston. On the side of the second piston opposite the combustion chamber is a control chamber with inlets and outlets for controlling movement of the second piston. The second piston is used to increase the compression ratio without appreciably reducing the expansion ratio. Alternatively, the second piston may be used as a pump to pump fluid from the control chamber. In yet another alternative method of operation, the second piston can be driven outward within the cylindrical recess to an extent which varies in accordance with power demand, thereby varying the compression ratio in accordance with the power demand.

摘要： A variable compression piston assembly includes a plurality of pistons, a transition arm coupled to each of the pistons, and a rotating member mounted for pivoting movement to slide along an axis of the drive member. Movement of the rotating member relative to the drive member changes the compression ratio of the piston assembly. An engine assembly includes first and second piston assemblies mounted back-to-back and 180° out of phase. A joint for positioning between first and second pistons includes an outer member and an inner member. The outer member is configured for movement relative to the pistons along a first axis perpendicular to the common axis of the pistons. The inner member is mounted within the outer member for rotation relative to the outer member about a second axis perpendicular to the first axis and the common axis.

摘要： The addition of volume reducing piston 28 to a “Two stroke engine with a plunger” through cylinder head 4 so that volume reducing piston 28 can get between cylinder head 4 and plunger body 11 and reduce the amount of fluid sucked into the engine. Also added to the engine is spring 34 to move volume reducing piston 28, and electro magnet 38 so that volume reducing piston 28 does not move at selected times. When electro magnet 38 is energized, volume reducing piston 28 is caught by electro magnet 38, so that volume reducing piston 28 does not move from cylinder head 4 when plunger body 11 goes to the bottom of its stroke, the amount of fluid to be compressed is not reduced, and the engine operates in a greater power output mode. When electro magnet 38 is not energized, both plunger body 11 and volume reducing piston 28 go the bottom of the stroke, the amount of fluid to be compressed is reduced and the engine operates in an efficient reduced power mode with almost complete expansion of the fluid-fuel charge.
摘要翻译：通过气缸盖4将减压活塞28添加到“具有柱塞的两冲程发动机”，使得减小活塞28可以在气缸盖4和柱塞体11之间获得并且减少吸入发动机的流体的量。还向发动机添加弹簧34以移动减小体积的活塞28和电磁体38，使得体积减小活塞28在选定的时间不移动。当电磁体38被通电时，体积减小活塞28被电磁体38捕获，使得当柱塞体11到达其行程的底部时，体积减小活塞28不会从气缸盖4移动，要被压缩的流体的量并没有减少，并且发动机工作在更大的功率输出模式。当电磁体38未通电时，柱塞体11和减容活塞28都移动到行程的底部，所以要压缩的流体的量减少，并且发动机以有效的降低功率模式运行，几乎完全膨胀流体 - 充电

The engine includes primary cylinders that communicate with secondary cylinders and in every primary cylinder there is movably arranged a primary piston that is connected to the first crankshaft and in every secondary cylinder there is movably arranged a secondary piston that is connected to the second crankshaft. The first and second crankshafts are connected to each other by means of a transmission adapted with the device that includes a crankshaft extension for obtaining the control of the phase angle, the extension being fixed against rotation and displaceably connected to one of the crankshafts and via a grooved portion rotationally connected to the second of the crankshafts. When the crankshaft extension in displaced, rotation is obtained in the grooved portion that results in a corresponding phase angle shift.
