ABSTRACT:
An automotive internal combustion engine comprises a cylinder block having at its bottom section a plurality of main bearing supporting sections, a bearing beam structure secured to the cylinder block bottom section and including a plurality of main bearing caps each cooperating with a main bearing supporting section of the cylinder block, and a beam section securely connecting the main bearing caps with each other, and a support arm disposed on an end portion of the bearing beam structure and rigidly connected to the lower section of a transmission bell housing, thereby effectively suppressing the angular displacement of the cylinder block relative to the transmission bell housing.
