摘要：
A reciprocating-piston internal combustion engine having a hydraulic adjustment mechanism which is assigned to a connecting rod and which comprises at least one eccentric, for adjusting at least one variable compression ratio in at least one cylinder of the reciprocating-piston internal combustion engine by means of a change in an effective length of a connecting rod. Also proposed is a method for changing the effective length of a connecting rod.
