Abstract

In a reciprocating piston internal combustion engine with a piston which is displacably arranged in a cylinder and is coupled in to a connecting rod whose movement can be transmitted to a crankshaft via a crank, a transmission element is provided between the connecting rod and the crank of the crankshaft and the movement of the transmission element can be manipulated by means of a control arm for an adjustment of the compression ratio of the engine. The transmission element is coupled to the crank via a joint disposed in the intermediate region between a bearing connection of the transverse lever structure with the control arm and a bearing connection of the transverse lever with the connecting rod, the bearing connection of the transverse lever with the connecting rod, the crank and the control arm being arranged in a predetermined relationship.
