Abstract
A connecting rod () has a crankpin bearing eye () attached to a crankshaft () and a connecting-rod bearing eye () attached to a piston. An eccentric adjustment device () adjusts an effective connecting rod length and has eccentric rods () that engage a lever () of the eccentric adjustment device (). Each eccentric rod () has a piston () guided in a hydraulic chamber (). The hydraulic chambers () can be charged with hydraulic oil from first hydraulic lines () that lead to the crankpin bearing eye () and second hydraulic oil lines () that lead from the crankpin bearing eye (). Check valves () prevent a backflow of hydraulic oil back into the second hydraulic lines (). At least one filter prevents an ingress of contaminants from the crankshaft into the hydraulic chambers () via the hydraulic oil.
