Claim:
1. An internal combustion engine comprising: at least one piston axially displaceable in a cylinder over a maximal stroke; and a connecting rod device for adjusting a compression of the internal combustion engine, said connecting rod device comprising a transverse lever having opposing ends and being connected on one of the opposing ends to a connecting rod via a first joint, and on the other one of the opposing ends being connected via a second joint with an actuatable control lever, said connecting rod being articulately arranged in the piston said control lever being arranged pivotal about a third joint, said transverse lever being connected between the first joint and the second joint with a crankpin of a crankshaft via a fourth joint, said crankpin being spaced apart from a rotation axis of the crankshaft, wherein a lateral distance between the rotation axis of the crankshaft and the third joint in relation to the maximal stroke of the piston is at least −1.0, in particular −1.23 or −1.78 so that pivot angles of the connecting rod device are reduced and as a result a friction in the joints is reduced.
