Abstract
A connecting rod (10) has a pin bearing eye connected to a crankshaft and a connecting rod bearing eye (12) connected to a piston. An eccentric adjusting device (13) adjusts an effective connecting rod length and has eccentric rods (15, 16) that act on an eccentric lever (14) of the adjusting device (13). The eccentric adjusting device (13) has an eccentric (36) guided in a recess of the lever (14) and a recess for receiving a gudgeon pin (37). Lubricating oil bores extend radially of the eccentric in the connecting rod bearing eye (12) and in the eccentric (36). Lubricating oil builds up via the lubricating oil bores between the connecting rod bearing eye (12) and the eccentric (36) and between the eccentric (36) and the gudgeon pin (37). Lubricating oil bores of the eccentric (36) are diametrically larger than lubricating oil bores of the connecting rod bearing eye (12).
