ABSTRACT:
An automotive internal combustion engine comprises a cylinder block having a plurality of cylinder bores and a plurality of bearing bulkheads, and a bearing beam structure secured to the bottom part of the cylinder block and including a plurality of main bearing cap sections each of which associates with each cylinder block bearing bulkhead to rotatably support the journal of a crankshaft, and two beam sections for securely connecting all the bearing cap sections, the two beam sections extending parallel with the axis of the crankshaft and being located at the opposite side portions, respectively, of each bearing cap section, thereby improving the strength of the main bearing cap sections and the cylinder block bearing bulkheads against the tortional and flexural vibrations to effectively suppress the vibrations of a cylinder block skirt section and an oil pan.
