An internal combustion engine has a multi-joint crank drive wherein the multi-joint crank driver includes a plurality of coupling members which are rotatably supported on crank pins of a crank shaft and a plurality of hinged connecting rods which are rotatably supported on crank pins of an eccentric shaft wherein each of the coupling members is pivotally connected to a piston connecting rod of a piston of the internal combustion engine and one of the articulation connecting rods. In order to enable to largely or completely compensate inertia forces, it is proposed according to the invention to equip the internal combustion engine with a single balance which serves for neutralizing second order inertia forces.

An actuating drive for valve drives having a variably adjustable stroke, for actuating valves of internal combustion engines is provided, which can be arranged in cylinder heads having usual dimensions, next to the valve activation mechanisms, in advantageous manner. The element that is changeable in its angle position is provided with a guide toggle coupled in fixed rotational manner, which is in engagement with an actuating shaft arranged adjacent to it, guided in the cylinder head in displaceable manner. This actuating slide has an actuating bridge in the region of the actuating path, with which contact surfaces of the actuating lever are engaged on one or both sides. The actuating slide is coupled with an actuating motor, which effects the axial actuating movements of the actuating slide counter to the forces introduced by the actuating lever. It is advantageous if the actuating slide is arranged on the side of the cylinder head opposite the camshaft, and thereby fits advantageously into the usual design of cylinder heads.

The invention relates to an assembled crankshaft composed of a plurality of crank cheeks which can be connected at one side to a main bearing journal and at the other side to a connecting rod bearing journal. The invention is based on the object of providing a crankshaft which is assembled from a plurality of individual parts, which is simple and quick to mount, which is characterized by a weight reduction and with which satisfactory lubrication of the bearing regions can be provided. According to the invention, the crank cheeks are provided at both sides with a ring-shaped groove for receiving the tubular main bearing journal and connecting rod bearing journal. In addition, the crank cheeks are provided with openings for a sleeve, which sleeves are in each case arranged within the main bearing journal and connecting rod bearing journal and are connected in a form-fitting and/or force-fitting manner to the crank cheeks.
