Abstract (en)
[origin: US2007000461A1] The invention is characterized in that the gas exchange valves of a cylinder are displaced in a displacement unit ( 15, 34 ) jointly and independently of the displacement of the displacement devices of the other cylinders. Every displacement unit ( 15, 34 ) is associated with separate actuators for actuating the same. Angle of rotation sensors ( 42, 43 ) are provided to detect the angle or rotation signals of the crankshaft and the camshaft or any other shaft rotating at half the crankshaft speed. These angle of rotation signals are used to derive the common idle phase of all valves of a cylinder to be jointly adjusted, a control unit ( 44 ) effecting the displacement of every displacement unit ( 15, 34 ) during said common idle phase.
