Abstract: A camshaft drive system for an internal combustion engine, includes a camshaft including a plurality of cam lobes thereon. A planetary gear system including a first component drivingly connected to the camshaft. A motor is drivingly connected to a second component of the planetary gear system and a sprocket is driven by the internal combustion engine and drivingly connected to a third component of the planetary gear system. A controller controls operation of the motor for selectively driving the second component at a same speed as the third component for imparting rotation to the camshaft and for selectively preventing rotation of the second component of the planetary gear system for preventing rotation of the camshaft.

Abstract: Presented are variable compression ratio and independent compression and expansion engines, methods for making/operating such engines, and vehicles equipped with such engines. An engine assembly includes an engine block with a cylinder bore defining a combustion chamber, and a piston movable within the cylinder bore. A valve assembly, which is fluidly coupled to the combustion chamber, selectively introduces/evacuates fluid from the combustion chamber. A crankshaft is supported by the engine block and rotatable on a first axis. A multipoint linkage, which drivingly engages the piston to the crankshaft, rotates on a second axis 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 operable to selectively rotate the multipoint linkage on the second axis, and is operable to selectively unseat the valve assembly.

Abstract: An engine variable compression ratio arrangement can be equipped in an internal combustion engine. The engine variable compression ratio arrangement includes a planetary gear set. The planetary gear set receives rotational drive input from an engine crankshaft, and the planetary gear set transmits rotational drive output to an eccentric shaft. The rotational position of the eccentric shaft is shifted relative to the rotational position of the engine crankshaft by way of the planetary gear set. This shifting varies the compression ratio of the internal combustion engine.
