Abstract
A connecting rod (10) has a pin bearing eye for attaching the connecting rod (10) to a crankshaft, a connecting rod bearing eye (12) for attaching the connecting rod (10) to a piston of a cylinder, and an eccentric adjusting device (13) for adjusting an effective connecting rod length. The eccentric adjusting device (13) has eccentric rods (15, 16) that act on an eccentric lever (14) of the eccentric adjusting device (13). The eccentric adjusting device (13) also has an eccentric (36) with a bore for receiving a gudgeon pin (37). Lubricating oil bores (38, 39, 40, 41) in the connecting rod bearing eye (12) and in the eccentric (36) enable a lubricating oil film to be built up between the connecting rod bearing eye (12) and the eccentric (36) and also between the eccentric (36) and the gudgeon pin (37).
