Abstract

The present disclosure relates to a device for lubricating an internal combustion engine having a crankshaft, which is connected to at least one connecting rod. The device has at least one first flow limiter, in particular a restrictor, for reducing a lubricating fluid flow of a lubricating fluid stream passed to the at least one first flow limiter. The device has a plurality of crankshaft bearings for the rotatable support of the crankshaft, wherein the plurality of crankshaft bearings is provided in fluid communication downstream of the at least one first flow limiter. The device has at least one big end bearing for the rotatable support of the at least one connecting rod, wherein the at least one big end bearing is provided in fluid communication downstream of at least one crankshaft bearing of the plurality of crankshaft bearings.
