Abstract
An oil pan structure for the cylinder block of an internal combustion engine for storing lubricating oil in the oil pan. A volume body submergible at least partly below the oil level for displacing a volume of oil when the oil is titled by displacement to one side in the oil pan as a result of the running condition of the motor vehicle having the engine with the oil pan structure, such as during turning, acceleration, deceleration or banking. The volume body has an inlet opening positioned near an allowable upper limit oil level for a predetermined maximum oil tilting condition for introducing into the volume body the lubricating oil which exceeds the allowable upper limit oil level. The oil pan structure also has an oil discharge passage from the lower portion of the volume body.
