    Abstract: A variable compression connecting rod system (10) located in an internal combustion engine (12) and a method of assembly can include a connecting rod (28) mountable to a piston pin (26) having a first longitudinal axis at one end and 5 mountable to a crankpin (22) having a second longitudinal axis at a second end portion (36). A hydraulically actuated eccentric rotor (52) rotatable about one of the first and second longitudinal axis. The eccentric rotor (52) including first and second vanes (54a, 54b) for driving the rotor between first and second angular positions in response to fluid pressure acting on the first and second vanes. The eccentric rotor 10 (52) having an eccentric surface area with different radial distances (80, 82) movable into alignment with a longitudinal axis of the connecting rod (28) for varying a longitudinal length of the connecting rod (28) between the first and second longitudinal axis.

    Abstract: A cam phaser (30, 130, 230) dynamically adjusts a rotational relationship of a camshaft (32) of an internal combustion engine with respect to an engine crankshaft operably connected with a phaser sprocket (42, 142, 242). The cam phaser (30, 130, 230) can include a planetary gear assembly having a ring gear (34, 134, 234) driven by the phaser sprocket (42, 142, 242), a planetary gear carrier (36, 136, 236) connected to the camshaft (32), a sun gear (38, 138, 238), and at least one rotatable planetary gear (40, 140, 240). The cam phaser (30, 130, 230) 236 can include a sprocket housing (44, 144, 244) connected with the phaser sprocket (42, 142, 242) and operable for connection with the ring gear (34, 134, 234), a cover plate (46, 146, 246) secured to the carrier (36, 136, 236), and a adapter (48) connected between the sun gear (38, 138, 238) and an electric motor (47) for changing an angular position of the sun gear (38, 138, 238) and adjustably varying a cam phase position of

    Abstract: A planetary gear assembly (30) and method of assembly in an electric camshaft phaser (20) with a split ring gear including a drive-side ring gear portion (32) rotatable by an engine crankshaft and an output-side ring gear portion (34) that can be connected to a camshaft (22). A plurality of rotatable planetary gears (36a, 36b, 36c) can be interposed between the split ring gear and the sun gear (28). The output-side ring gear portion (34) can have a different number of teeth than the drive-side ring gear portion (32) by a value corresponding to a multiple of the number of planetary gears (36a, 36b, 36c). A compliant planetary gear carrier (40, 140) can support the plurality of planetary gears (36a, 36b, 36c) allowing variance of a normally equidistant distance between separate spaced rotational axes of at least two of the planetary gears (36a, 36b, 36c) to selectively compensate for mechanical tolerances of the drive-side ring gear portion (32) and the output-side ring gear portion (34) of the split ring gear.

    Abstract: The variable compression ratio piston system for an engine adjusts the compression ratio of the engine piston by way of hydraulic fluid distributed between a pair of chambers formed in a pair of bores receiving control pistons mechanically coupled to the engine piston. A control valve selectively permits flow of hydraulic fluid between the high compression ratio line and the low compression ratio line. A variable force solenoid controlled by an engine control unit preferably controls the position of the control valve. The position of the spool controls whether hydraulic fluid can flow toward the first chamber, toward the second chamber, or not at all. Flow of hydraulic fluid is actuated by alternating forces from inertial and combustion forces on a crankshaft from operation of the engine.

    Abstract translation: 用于发动机的可变压缩比活塞系统通过分配在形成在一对孔中的液压流体来调节发动机活塞的压缩比，所述一对腔室形成在机械联接到发动机活塞的控制活塞的一对孔中。 控制阀选择性地允许液压流体在高压缩比线和低压缩比线之间流动。 由发动机控制单元控制的可变力电磁阀优选地控制控制阀的位置。 卷轴的位置控制液压流体是否能够朝向第二室流动，或者根本不流动。 液压流体的流动由来自发动机运转的曲轴上的惯性和燃烧力的交变力致动。
