Abstract
An internal combustion engine has a multi-link crankshaft drive with a plurality of coupling elements rotatably mounted on crankpins of a crankshaft and a plurality of articulated connecting rods rotatably mounted on crankpins of an eccentric shaft, wherein each of the coupling elements is pivotally connected to a piston connecting rod of a piston of the internal combustion engine and to one of the articulated connecting rods. A balance shaft, which is driven by a crankshaft via a phase adjuster, is provided in order to at least partially attenuate second-order inertia forces occurring in the internal combustion engine.
