Description

Technical Field

[0001] The utility model relates to the technical field of oil pans, in particular to an engine oil pan. Background Art

[0002] The removable oil pan is located at the bottom of the engine and seals the crankcase, serving as the outer shell for the oil reservoir. The oil pan, also known as the lower crankcase, is the lower half of the crankcase. It encloses the crankcase as the outer shell of the oil reservoir, preventing impurities from entering. It also collects and stores lubricating oil that flows back from the engine's friction surfaces, dissipating some of the heat and preventing lubricating oil oxidation. Oil pans are typically stamped from thin steel plates and are equipped with an oil-stabilizing baffle to prevent oil surface oscillation and splashing caused by engine turbulence, thereby facilitating the sedimentation of lubricating oil impurities. A dipstick is mounted on the side for checking the oil level. A drain plug is also located at the lowest point of the oil pan.

[0003] Based on the above, the inventors have found the following problems: current engine oil pans usually use natural heat dissipation to dissipate heat from the lubricating oil, which has a relatively low heat dissipation efficiency. When the lubricating oil temperature is high, it is easy to affect the lubrication performance and is inconvenient to use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an engine oil pan is provided to achieve the purpose of having more practical value. Utility Model Content
