ABSTRACT:
A bearing beam structure is secured to a cylinder block of an internal combustion engine and includes a plurality of main bearing cap sections each of which associates with each bearing section of the cylinder block so as to rotatably support a crankshaft. At least a beam section is rigidly connected to the lower end portion of each bearing cap section to securely connect all the bearing cap sections with each other. Additionally, first and second side wall sections are rigidly connected to the opposite side portions of each bearing cap section to securely connect all the bearing cap sections with each other. Accordingly, the bearing beam structure is improved in rigidity to suppress various vibrations of the cylinder block, thereby effectively achieving total engine noise reduction.
