ABSTRACT:
An internal-combustion engine has a rocker lever valve gear equipped with a roller for the cam-controlled actuating of charge cycle valves. Each rocker lever of the rocker lever valve gear has an arm provided with a circular-arc-shaped longitudinal part. Along the longitudinal part, an abutment point can be shifted as a function of parameters of the internal-combustion engine. The resulting changed leverages on the rocker lever vary the valve lift.
