Description

Technical Field

[0001] The utility model relates to the technical field of automobile engine systems, in particular to a wet oil pan structure of an engine. Background Art

[0002] The main function of the oil pan of a car engine is to store lubricating oil. When the engine starts, the oil pump pumps the lubricating oil to the main oil channel and each branch oil channel to provide lubrication for each relatively moving part. When the engine stops running, part of the lubricating oil returns to the oil pan under the action of gravity, and can also dissipate some heat, play a cooling role, and prevent the lubricating oil from oxidizing.

[0003] Engine oil pans are generally divided into two categories: wet type and dry type. Due to the simple structure, low cost and easy maintenance of wet oil pans, they are widely used in the market. Most automobile engines on the market currently use wet oil pans. When a vehicle is driving under poor road conditions, the front, rear and left and right inclination angles are large, and the lubricating oil in the oil pan fluctuates greatly, which will cause the bearing to be immersed as a whole, increase the rotational resistance of the crankshaft, and cause the engine performance to decline. Excessive fluctuations in the lubricating oil level will also cause the lubricating oil under the filter to decrease, making it difficult to absorb oil, causing poor lubrication and even burning of the bearing and cylinder scuffing. Therefore, it is necessary to invent a new engine wet oil pan structure. Utility Model Content

[0004] The utility model aims to provide an engine wet oil sump structure to solve the problem that when a vehicle is driving on a poor road condition, the lubricating oil level in the oil sump of a traditional wet oil sump fluctuates greatly, resulting in poor lubrication and affecting engine performance.
