ABSTRACT:
An internal combustion engine comprises a cylinder block having at its bottom part a plurality of bearing sections; and a bearing beam structure including a plurality of main bearing cap sections each of which associates with the cylinder block bearing section to rotatably support a crankshaft, first and second beam sections for securely connecting all the bearing cap sections and extending parallel with the axis of the crankshaft, the distance between the outer-most side-surfaces of the first and second beam sections being equal to or smaller than the width of each bearing cap section, and at least four cap bolts for fastening each bearing cap section onto the cylinder block, thereby effectively suppressing the vibration of the bearing beam structure itself and accordingly the vibration of the lower part of the cylinder block.
