Description

Technical Field

[0001] The utility model relates to the technical field of automobile engine accessories, in particular to an improved engine oil breather pot. Background Art

[0002] During the operation of a car engine, a large amount of blowby gas consisting of oil vapor and combustible mixture will be generated in the crankcase. If the blowby gas is not effectively treated, it will directly enter the intake pipe, causing carbon deposits on the wall of the intake pipe, thereby affecting the performance and life of the engine. For these blowby gases, an oil breather is usually used. Although the traditional oil breather can achieve oil-gas separation to a certain extent, the separation efficiency and the influence of the weather in the use environment are still insufficient.

[0003] During the oil-gas separation process, existing oil breathers often have problems such as incomplete separation, oil easily flowing back into the intake pipe resulting in increased carbon deposits, and limited filtering effect. These problems not only affect the performance and life of the engine, but also increase maintenance costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the prior art has the disadvantage of limited efficiency in the oil-gas separation process, for which we propose an improved engine oil breather.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: an improved engine oil breather pot, comprising a breather pot body, an air inlet pipe is installed on one side of the breather pot body, a labyrinth-type air inlet filter unit and a labyrinth-type air outlet filter unit are installed inside the breather pot body, a honeycomb baffle is fixedly connected to the inside of the breather pot body, a partition plate is installed on the top of the honeycomb baffle, an air outlet pipe is installed on the top of the labyrinth-type air outlet filter unit, an oil storage cavity is opened at the bottom end of the honeycomb baffle, and an oil outlet pipe is installed at the bottom end of the oil storage cavity.

[0006] Preferably, an air inlet cooling chamber and an air outlet cooling chamber are respectively opened on both sides of the partition plate.

[0007] Preferably, the internal components of the breathable kettle body are welded by stainless steel laser.

[0008] Preferably, an oil level sight gauge is installed on the other side of the breathable pot body.

[0009] Preferably, connecting plates are installed on the surfaces of the labyrinth-type air inlet filter unit and the labyrinth-type air outlet filter unit, the internal threads of the connecting plates are connected to threaded rods, and a limiting groove is provided on the top of the air-permeable kettle body.

[0010] Technical effects and advantages of the utility model:

[0011] In the utility model, by setting a series of baffles inside the maze-type air intake filter unit and the maze-type air outlet filter unit, when the blow-by gas enters from the intake pipe, it needs to go through multiple turns and collisions in the maze-type path, so that the oil particles are deposited on the inner wall or the honeycomb baffle of the maze-type air intake filter unit under the action of inertia, while the gas continues to flow forward, and when the blow-by gas enters the maze-type air outlet filter unit, the clean gas that has undergone preliminary separation is further purified here to ensure that the gas with almost no residual oil enters the engine intake pipe. Through the above design, the separation efficiency of the engine oil and the gas can be significantly improved, and the possibility of the engine oil entering the pipe is reduced. Moreover, due to the improvement of the oil-gas separation efficiency, the clean gas entering the engine pipe is purer, and the risk of the engine oil carbonizing and forming carbon deposits at high temperature is reduced.

[0022] Working principle: through the setting of a series of baffles inside the labyrinth-type air intake filter unit 3 and the labyrinth-type air outlet filter unit 7, when the blow-by gas enters from the intake pipe 2, it needs to go through multiple turns and collisions in the labyrinth-type path, so that the oil particles are deposited on the inner wall of the labyrinth-type air intake filter unit 3 or the honeycomb baffle 5 under the action of inertia, and the gas continues to flow forward. When the blow-by gas enters the labyrinth-type air outlet filter unit 7, the clean gas that has undergone preliminary separation is further purified here to ensure that the gas with almost no oil residue enters the engine pipeline. Through the above design, the separation efficiency of engine oil and gas can be significantly improved, and the possibility of engine oil entering the pipeline is reduced. Moreover, due to the improvement of the oil-gas separation efficiency, the clean gas entering the engine pipeline is purer, reducing the risk of carbonization of engine oil at high temperature to form carbon deposits.
