Abstract
The present invention discloses an engine oil pan, which includes a cylinder block, wherein a plurality of arc-shaped grooves are disposed on the second end surface of the cylinder block along the axial direction of a crank shaft; the arc-shaped grooves form arc-shaped bulges in a sunk portion on the first end surface of the cylinder block; the arc-shaped bulges divide the sunk portion into first space and second space; a platform is disposed inside the sunk portion of the cylinder block; and the height of the platform is lower than the height of the arc-shaped bulges. The technical solution employed by the present invention enables lubricating oil in the engine oil pan to flow more effectively, and enables the lubricating oil in the oil pan to be utilized more effectively when the engine is used in any position.
