摘要： 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.

摘要： The present invention discloses an engine oil supply system, which includes an oil pan for storing lubricating oil. An oil suction pipe is disposed in the oil pan, the oil suction pipe is twisted in the oil pan, and at least two oil suction portions are disposed on the oil suction pipe, so that at least one oil suction portion is below a lubricating oil level when the engine is in any position. The technical solution disclosed by the present invention can ensure that the lubricating oil can enter each part of the engine for lubrication through the oil supply system when the engine is used either in a leant or inverted manner.

摘要： A carburetor base of an engine defines an axial through hole and a pulsation hole channel. An anti-blocking component is mounted inside the axial through hole and defines an air inlet channel. The air inlet channel communicates with the pulsation hole channel so as to avoid blocking of condensed fuel oil inside the pulsation hole channel.
