The present disclosure relates to an pneumatic hybrid internal combustion engine with at least one combustion chamber composed of a cylinder in which a piston is arranged mechanically interconnected to a crank shaft via a piston rod. An inlet valve and an exhaust valve are both mechanically interconnected via a valve gear to the crank shaft. The engine further includes at least one charge valve which is actuated by a charge valve actuator in a fully variable manner such that the engine can be operated in a four stroke hybrid mode.
