ENGINE FOR VEHICLE

摘要

In an engine for a vehicle including a bearing cap integral type oil pan which has a plurality of bearing cap sections integrally provided thereon and which is integrally coupled to a cylinder block, connecting bolts are screwed into the bearing cap sections from the cylinder block to integrally couple the cylinder block and the oil pan to each other. An oil pan chamber, which is an as-cast bore made by drawing a die in an axial direction of a crankshaft, is defined to extend continuously in the axial direction of a crankshaft between the bearing cap sections and bottom wall of the oil pan. Thus, the oil pan can be produced simply, at a low cost , by a casting process and moreover, it is possible to reduce the weight and size of the oil pan and increase the rigidity of the oil pan.
