Embodiment Construction

[0060] The present disclosure provides an engine oil pan, the engine oil pan can have a relatively small volume capacity under the premise of ensuring the capacity, can avoid lubricating oil suction, and can effectively filter lubricating oil impurities .

[0061] In the process of realizing the present disclosure, the inventors found that during the normal driving process of the car, there will be different postures such as climbing, downhill, sideways, etc., but the engine oil is in a liquid state. The surface is always kept level, and the oil sump needs to be designed for the boundary according to the actual worst conditions. Usually, the oil pan is designed with the car tilting 30° in the eight directions of forward, rear, left, right, left front, right front, left rear and right rear respectively as the maximum tilting attitude of the engine. Since the oil suction port is arranged in the oil sump cavity, the oil suction port must always be below the lubricating oil liqui...

Abstract

The invention provides an engine oil pan. The engine oil pan comprises an oil baffle and a guide pipe, wherein the oil baffle is fixed to an inner cavity of a shell body of the engine oil pan, dividesthe inner cavity of the shell body into a shell body large end area and a shell body small end area and can block most lubricating oil in the shell body large end area, so that the engine oil pan isin an inclined state, an oil suction port can suck the oil, a first guide pipe end of the guide pipe is fixedly connected to a through hole formed in the oil baffle, in addition, the first guide pipeend is provided with a one-way valve allowing the lubricating oil to pass through in a one-way mode, and a second guide pipe end of the guide pipe extends to the bottom of the shell body large end area, so that the guide pipe can guide the lubricating oil in the shell body small end area into the shell body large end area through the one-way valve.

Description

technical field [0001] The present disclosure relates to the technical field of engines, in particular to an engine oil pan. Background technique [0002] The engine needs oil for lubrication during normal operation, and the oil pan is the main oil storage part of the engine. In addition to meeting the assembly requirements of the engine itself, the shape of the oil pan also depends on the space layout requirements of the vehicle. The oil storage capacity of the oil sump needs to meet the demand of engine lubricating oil. Engine lubricating oil not only lubricates the engine, but also cleans the moving parts, such as residual sand in the casting oil hole, carbon deposits and sludge on the surface of moving parts, metal or coating debris produced by abnormal wear of engine parts, etc. All can discharge the kinematic pair through the lubricating oil to ensure the normal operation of the engine. [0003] Usually, it is contradictory to ensure the oil volume requirement and m...
