An internal-combustion engine comprises at least two inlet stroke valves per cylinder, the courses of the strokes of these stroke valves being adjustable in different manners. The adjustment takes place by means of an eccentric shaft which displaces the supporting point of a transfer element disposed between each cam and each stroke valve, in which case the two eccentrics assigned to one cylinder are of a different geometry. The transfer element is formed by a valve lever which is supported on the eccentric and is actuated by the cam, which valve lever, in turn, acts upon a rocker lever. The respective contact surfaces are formed by rollers. A further transfer element, which has a crank path, is also described.
