A vehicle and method for controlling a vehicle having a variable displacement engine with an auxiliary machine connected directly to the engine crankshaft and to an energy storage device includes switching from a cylinder disablement (VDE) mode to a normal mode when the torque demand and engine speed lie outside an outer range defined by a first threshold (T.sub.out), and switching from the normal mode to the VDE mode when the torque demand and engine speed lie within an inner range, which lies within the outer range and defined by a second threshold (T.sub.in). When operating in a band between the two thresholds, the auxiliary machine draws energy from the energy storage device and supplements the output torque from the engine if operating in the VDE mode, and derives torque from the engine crankshaft to recharge the energy storage device if operating in the normal mode.

A phase adjuster assembly is disclosed herein that is configured to adjust a phase between a driving component and driven component of an internal combustion engine. The phase adjuster assembly includes an input gear configured to be driven by the driving component and an output gear configured to drive the driven component. A piston plate assembly is configured to adjust a phase between the driving component and the driven component via axial displacement of the piston plate assembly. A hydraulic fluid system is configured to selectively provide hydraulic fluid to a first piston control chamber on a first side of the piston plate assembly and to a second piston control chamber on a second side of the piston plate assembly to axially displace the piston plate assembly such that the phase between the driving component and the driven component is adjusted.

Combustion engine with a variable compression ratio which, according to the invention, includes the following items: engine body, crankshaft with crank pins mounted rotatably in the body, cylinders, pistons connected to the crankshaft via pin connecting rod sand control arms as well as the control arm rod located inside the engine body, with eccentrics mounted on it, on which eccentrics for each piston there are separately mounted control arms, it is characterized by the fact that on the control arm rod (19) aside from the rigidly mounted eccentrics (18), on which single control arms (14) are rotatably mounted, there are also rotatably mounted eccentrics (23), on which single control arms (14) are rotatably mounted, where preferably on the eccentrics (18) are mounted the control arms (14) for one row of cylinders (5), while for the eccentrics (23) are mounted the control arms (14) for the other row of cylinders (5), additionally the engine contains a mechanism for changing the compression ratio consisting of the control arm rod (19) with eccentrics (18, 23) mounted on the control arm rod (19) as well as coupling elements that connect the elements of the mechanism which ensure that neighboring eccentrics (18, 23) rotate in opposite directions.
