摘要 |
<p>n interna) combustion engine (20) comprises a cylinder block (22) including cylinder barrels (24), and main bearing bulkheads each having a bearing section; main bearing cap sections (46) respectively secured to the bearing bulkheads (30) so that each main bearing cap section (46) and the corresponding cylinder block bearing section (32) associate to constitute a main bearing (48) for rotatably supporting a crankshaft (34); and a bearing beam structure (50) detachably secured to the main bearing cap sections to connect the main bearing cap sections (46) with each other as a single unit, the bearing beam structure (50) including a plurality of beam sections (52, 54) which are disposed parallel with each other and extend along the row of the main bearing cap sections (46), the beam sections (52, 54) being connected with each other, thereby effectively decreasing engine noise while facilitating the handling of the engine parts before assembly.</p> |
