摘要： A multi-joint crank drive of an internal combustion engine, comprising a plurality of coupling members rotatably supported on crank pins of a crankshaft and a plurality of articulation connecting rods rotatably supported on crank pins of an eccentric shaft, wherein each of the coupling members is pivotably connected to a piston connecting rod of a piston of the internal combustion engine and to one of the articulation connecting rods. In order to reduce second order inertia forces, the multi-joint crank drive is designed or adjusted in such a way that a crankshaft rotational angle range of an intake phase is greater than 180 degrees; a crankshaft rotational angle range of a compression phase is less than 180 degrees; a crankshaft rotational angle range of an expansion phase is greater than 180 degrees; and a crankshaft rotational angle range of an exhaust phase is less than 180 degrees.
