CONNECTING ROD AND INTERNAL COMBUSTION ENGINE

摘要

A connecting rod (10) has a big end bearing eye (11) for attachment to a crankshaft and a small end bearing eye (12) for attachment to a piston of a cylinder. An eccentric adjusting device (13) adjusts an effective connecting rod length. The eccentric adjusting device (13) has eccentric rods (15, 16) that engage on an eccentric lever (14) of the eccentric adjusting device (13) so that, in the region of each eccentric rod (15, 16), a connecting pin (36) extends through apertures in the eccentric lever (14) and in the respective eccentric rod (15, 16). The aperture (37) in the respective eccentric rod (15, 16), through which the respective connecting pin (36) extends, and/or a section of the respective connecting pin (36) that extends through the aperture (37) in the respective eccentric rod (15, 16), has/have arched contours, at least in some section or sections.
