Abstract (en)
[origin: EP3214294A1] A technique capable of decreasing deformation of an oil pan attaching portion with good weight efficiency is provided. The oil pan rail portion (34) includes a first rail portion (34a) and a second rail portion (34b). A rail height of the first rail portion (34a) is formed higher than a rail height of the second rail portion (34b). A connecting portion (134b) between the first rail portion (34a) and the second rail portion (34b) is connected to a third journal supporting wall (27c) having the highest rigidity among the crank journal supporting walls (27). The rigidity of the first rail portion (34a) becomes larger than the rigidity of the second rail portion (34b) by such a reasonable structure, thus reasonably improving the rigidity of the first rail portion (34a) which tends to be structurally deformed easily. Further, weight increase can also be minimized, because the rail height of the oil pan rail portion (34) is not increased over the entire region along the cylinder row direction.
