ABSTRACT:
An oil pan for an internal combustion engine wherein the oil dropped on a shallow bottom section is rapidly returned into a sump. A plurality of guide ribs are disposed on the downstream side of the shallow bottom section which is located at the downstream side of the oil flow caused by the rotation of a crankshaft of the engine. The guide ribs are formed in an arcuate shape so as to curve toward the sump as they approach a side wall located at the downstream side, by which the oil flow is directed toward the sump. Additionally, a guide plate formed integrally with a baffle plate extends upwardly to guide the flowing oil into the sump.
