Claim:
1. An internal combustion engine with adjustable compression ratio with at least one cylinder and with a crank shaft at which at least one connecting rod engages, wherein at least one connecting rod includes a crank bearing eye for connecting to a crank shaft, a connecting rod bearing eye connecting to a piston of at least one cylinder and an eccentrical element adjustment device adjusting an effective connecting rod length, wherein the eccentrical element adjustment device includes an eccentrical element cooperating with an eccentrical element lever and eccentrical element rods engaging the eccentrical element lever, wherein the eccentrical element rods are loaded with a force generated by a hydraulic pressure in hydraulic cavities, wherein the eccentrical element lever includes at least one eccentrical element lever segment, wherein the at least one eccentrical element lever segment is positioned in an axial direction of the eccentrical element in front or behind a plane of symmetry of the piston, wherein the at least one eccentrical element lever segment is fixated at the eccentrical element, and wherein the plane of symmetry of the piston is orthogonal to the axial direction of the eccentrical element.
