Abstract

PURPOSE:To improve the rigidity of a cylinder block by disposing a reinforcing plate for interconnecting the lower ends of skirt portions of a cylinder block in a position other than a shallow tray portion of an oil pan and providing a stiff inner member partially overlapping said plate. CONSTITUTION:In an embodiment of a straight type 4-cylinder engine, an oil pan 10 disposed beneath a cylinder block 1 is formed of a rail portion 10a fixedly bolted to a cylinder block skirt portion 1b, a shallow tray portion 10b having a shallow bottom at the side (rear side) close to a transmission 3 and a deep tray portion 10c at the opposite side to said portion 10b. And between the cylinder block 1 and the deep tray portion 10c of oil pan 10 is disposed a reinforcing plate 15 for interconnecting the lower ends of skirt portions 1b. Also, a stiff inner member 16 overlapping partially the reinforcing plate 15 is disposed below the rear portion of engine so that the cylinder block 1 is reinforced.
