Abstract
An internal combustion engine comprises a cylinder block rigidly connected to a transmission and having cylinder bores and bearing sections; and a bearing beam structure including main bearing cap sections each associating with each cylinder block bearing section to rotatably support a crankshaft, first and second beam sections securely connecting the main bearing cap sections with each other and extending parallelly with the crankshaft axis, the first and second beam sections being located spaced from each other and along the respective opposite side portions of each bearing cap section, and first and second connecting sections respectively integral with the first and second beam sections and being rigidly connected to the transmission, thereby preventing the bearing beam structure from its axial vibration while contributing to an improvement in rigidity of a power unit entire including the transmission.
