The invention relates to an internal combustion engine comprising a valve drive which is arranged in the region of the cylinder head and is used to actuate a valve. Said internal combustion engine comprises a first drive means that can be rotated about a first rotational axis, a connecting rod that is connected to the first drive means in an articulated manner by means of a first connecting rod articulation, and a guiding element which is used to guide the connecting rod, can be pivoted about a guiding axis, and is connected to a second articulation of the connecting rod in an articulated manner. The position of the first rotational axis can be modified in relation to the cylinder head.
