Abstract (en)
[origin: DE19919734A1] The invention relates to a method and to a device for opening and closing a valve of an internal combustion engine. The aim of the invention is to reduced the energy required for opening and closing a valve of an internal combustion engine, especially one that is provided with an electromagnetic valve control. To this end, the kinetic energy of the valve is transferred to a mass and temporarily stored in a said mass.
