ABSTRACT:
An internal combustion engine comprises a cylinder block having a plurality of cylinder barrels and a plurality of bearing sections for the journals of a crankshaft; a bearing beam structure and including a plurality of main bearing cap sections each of which associates with each cylinder block bearing section to form a bore for rotatably receiving the crankshaft journal, each bearing cap section being formed with first and second projections which are spaced from each other and located opposite to each other with respect to the axis of the bore, and first and second beam members which are independent from but securely connected to the first and second bearing cap section projections, respectively, by bolts, thereby greatly reducing engine noise emission and improving the productivity of the engine.
