Abstract
A device lubricates a big-end bearing on a crankshaft of an internal combustion engine. The device includes a piston with a fluid channel and an outlet channel fluidically connected thereto, and a connecting rod. The connecting rod has a small connecting rod eye, a large connecting rod eye and a connecting channel. The small connecting rod eye is fluidically connected to the outlet channel. The connecting channel forms a fluidic connection between the small and large connecting rod eyes so that a cooling lubricant fluid can be supplied from the fluid channel to the large connecting rod eye via the outlet channel, the small connecting rod eye and the connecting channel. In this way, the big-end bearing can be lubricated by cooling oil from the fluid channel of the piston.
