摘要:
一种内燃机的油底壳结构包括油底壳(3)和设置在油底壳(3)内部的挡板(2),挡板(2)具有贮存部(21),贮存部(21)用于收集循环通过发动机以润滑和冷却所述发动机后流回的机油。所述贮存部具有以俯视图所视的呈大体矩形形状的大体平的底部(211),和从底部(211)向上延伸的前、左和右侧壁(212a、212b和212c)。所述贮存部也具有排油口(22),贮存部(21)中的机油通过排油口(22)排进油底壳(3)中。排油口的开口邻近且面向所述油底壳的壁(31)。
摘要(英):
An oil pan structure for an internal combustion engine includes an oil pan (3) and a baffle plate (2) provided inside the oil pan (3) having a storage section (21) for collecting oil that is returned after circulating through the engine to lubricate and cool the engine. The storage section has a generally flat bottom (211) with a generally rectangular shape as viewed in a plan view, and front, left, and right side walls (212a, 212b, and 212c) that extend upward from the bottom (211), The storage section also has an oil drain port (22) through which the oil in the storage section (21) is drained into the oil pan (3) , The opening of oil drain port is near and faces a wall (31) of the oil pan.
