See full text

A connecting rod (10) has a big end bearing eye (11) for attachment to a crankshaft, a small end bearing eye (12) for attachment to a piston, and an eccentric adjusting device (13) for adjusting an effective connecting rod length. The eccentric adjusting device (13) has eccentric rods (15, 16) that engage on an eccentric lever (14), an eccentric (36) that is guided in an aperture in the eccentric lever (14) and in the small end bearing eye (12) and an aperture for accommodating a piston pin (37). Lubricating oil bores (38, 39) are introduced into the small end bearing eye (12) via which a lubricating oil film can be built up between the small end bearing eye (12) and the eccentric (36). The small end bearing eye (12) has a larger radial wall thickness in those regions in which the lubricating oil bores (38, 39).
