Variable compression ratio and independent compression and expansion engines, methods for making/operating such engines and vehicles equipped with such engines are presented. The engine assembly includes an engine block having a cylinder bore defining a combustion chamber; and the piston can move in the air cylinder hole. A valve assembly fluidly coupled to the combustion chamber selectively introduces/discharges fluid from the combustion chamber. A crankshaft is supported by the engine block and rotatable on a first axis. A multi-point coupling device that drivingly engages the piston to the crankshaft rotates on a second axis that is offset from the first axis. A control shaft is supported by the engine block and rotates on a third axis offset from the first and second axes. The control shaft is operable to selectively rotate the multi-point coupling device on the second axis, and is operable to selectively disengage the valve assembly.

    提出可变压缩比以及独立压缩和膨胀发动机、用于制成/操作此类发动机的方法以及配备有此类发动机的车辆。发动机组件包括:具有气缸孔的发动机缸体,其限定燃烧室;以及活塞,所述活塞可在所述气缸孔内移动。流体地耦接到所述燃烧室的阀组件选择性地从所述燃烧室引入/排出流体。曲轴由所述发动机缸体支撑,并且可在第一轴线上旋转。使所述活塞驱动地接合到所述曲轴的多点联接装置在偏离所述第一轴线的第二轴线上旋转。控制轴由所述发动机缸体支撑并且在偏离所述第一和第二轴线的第三轴线上旋转。所述控制轴可操作成选择性地使所述多点联接装置在所述第二轴线上旋转,并且可操作成选择性地使所述阀组件脱开。
