ABSTRACT:
Crankshaft bearings suitable for a reciprocating piston-type internal combustion engine having multiple cylinders are arranged in a housing made of a light metal alloy and include bearing bores for a crankshaft crank pins of a crankshaft. The bores having first and second bearing sections with first and second thrust bearings extending across a longitudinal plane of the crankshaft on both sides of a bearing parting plane. The second thrust bearings are part of a crankshaft bearing bridge connected to a crankcase. At least a portion of two thrust bearings of the crankshaft bearing bridge having neighboring or adjoining bore halves of the bearing bores is supported by connecting elements. The thrust bearings of the internal combustion engine open into longitudinal walls of the crankshaft bearing bridge with local widened areas in between.
