摘要
Systems are provided for an engine block assembly comprising a cylinder block, bearing caps and crankshaft main bearings. In one example, an engine block assembly may comprise a cylinder block, a bearing cap bolted to the cylinder block, the bearing cap comprising: a first recess included in a first surface, a second recess included in a second surface opposite the first surface, and a thrust surface interfacing with a crankshaft bearing, where a rigidity of the thrust surface may vary along an axial profile of the thrust surface due to the first and second recesses. When the bearings caps are bolted to the cylinder block, the thrust surface may bend due to its variable rigidity, and as such may induce a bend in an axial profile of the crankshaft bearing to a more convex shape.
