As shown in fig. 1 to 3, an embodiment of the present invention provides an oil separator including:
the oil-gas separation device comprises a shell 1, wherein a plate body inlet and outlet facing a first side plate 101 of the shell 1 are formed in the shell 1, the first side plate 101 is communicated with the plate body inlet and outlet to form an accommodating cavity, an oil-gas separation area 4 is formed by a second side plate 102 of the shell 1 and the plate body inlet and outlet, and an oil inlet 2 and an oil outlet 3 which are respectively communicated with the accommodating cavity are formed in the shell 1; wherein the first side plate 101 is disposed opposite to the second side plate 102;
a movable first oil-gas separation plate 5 is arranged in the accommodating cavity, and the first oil-gas separation plate 5 can pass through the plate body inlet and outlet and move towards an oil-gas separation area 4 formed by the shell 1; wherein the first oil-gas separation plate 5 moves between a first position in the housing chamber and a second position at least partially in the oil-gas separation zone 4;
when the first oil-gas separation plate 5 is located at the second position, the lubricating oil flowing in from the oil inlet 2 flows out through the oil outlet 3.
In the embodiment of the invention, under the working condition of high-speed running of the engine, the pressure is increased, the oil amount of the lubricating oil in the accommodating cavity is increased, the oil pressure of the lubricating oil acts on the first oil-gas separation plate 5, so that the position of the first oil-gas separation plate 5 is changed, the lubricating oil moves between the first position and the second position, and particularly, when at least part of the first oil-gas separation plate 5 moves to a position exceeding the oil outlet 3, the lubricating oil flows out of the oil outlet 3, so that the pressure loss of a crankcase ventilation system, the flow rate of oil-gas mixture, the oil-gas separation efficiency and the like are changed, the oil-gas separation efficiency is changed, and the purpose of improving the oil-gas separation effect is further realized. The oil-gas separator of the embodiment is suitable for various engine working conditions, and can ensure that the pressure balance of the crankcase does not change violently no matter the engine is in a high-load working condition or a low-load working condition, and reduce the sealing pressure of each sealing surface in the engine. In an optional embodiment of the present invention, the gas-oil separator further comprises:
the second oil-gas separation plate 6 is arranged in the oil-gas separation area 4 and is fixedly connected with the shell 1; when the first oil-gas separation plate 5 is located at the second position, at least part of the first oil-gas separation plate 5 is overlapped with the second oil-gas separation plate 6.
It should be noted that, when the engine operates, lubricating oil flows into the holding intracavity from oil inlet 2, along with the load of engine is higher and higher, the fluid volume of lubricating oil increases, and pressure grow promotes first oil-gas separation board 5 and passes the plate body access & exit and move gradually to the second position of at least part and the coincidence of second oil-gas separation board 6 by first position to make on oil-gas mixture striking first oil-gas separation board 5 and second oil-gas separation board 6, reach the purpose that increases the oil-gas separation effect.
Specifically, the first oil-gas separation plate 5 is a T-shaped plate structure.
In this embodiment, in order to increase the area of the oil pressure of the lubricating oil acting on the first oil-gas separation plate 5, the first oil-gas separation plate 5 is designed to be a T-shaped plate structure, which is beneficial to pushing the first oil-gas separation plate 5 to move towards the oil-gas separation region 4 when the pressure is increased.
Further, the second oil-gas separation plate 6 and the first oil-gas separation plate 5 are respectively provided with a plurality of through holes.
Here, the first oil-gas separation plate 5 may be made of a material selected from filter cotton, filter paper, felt, t-plate, and the like.
In an optional embodiment of the present invention, the first oil-gas separation plate 5 is sleeved with an elastic resetting device 7.
In this embodiment, when first oil-gas separation board 4 moved to the second position by the first position under the impetus of lubricating oil gradually, lubricating oil flowed out by oil-out 3, and the pressure of holding intracavity diminishes, and through elasticity resetting means 7, first oil-gas separation board 4 resets to the first position by the second position, prevents that first oil-gas separation board 4 atress from taking place to damage.
It should be noted that, when the load of the engine is reduced, the pressure becomes smaller, and the elastic resetting device 7 may also act on the first oil-gas separating plate 5, so that the first oil-gas separating plate 5 is reset from the second position to the first position, and at this time, the whole oil-gas separator can still maintain a higher oil-gas separation efficiency.
In particular, said elastic return means 7 comprise a square spring.
Here, in order to adapt to the structural shape of the first oil-gas separation plate 5, the elastic return means 7 is a square spring. Meanwhile, in order to enhance the elastic reset capability, the number of the square springs is increased in adaptability.
Further, on the first oil-gas separation plate 5, one side of the elastic resetting device 7 close to the plate body inlet and outlet is also provided with a sealing gasket 8, and through the sealing gasket 8, the first oil-gas separation plate 5 is connected with the plate body inlet and outlet of the shell 1 in a sealing manner, so that the sealing performance of the accommodating cavity is ensured, and lubricating oil is prevented from flowing into the oil-gas separation area 4.
Embodiments of the present invention also provide an engine including an oil-gas separator as described above.
The engine adopting the oil-gas separator changes the internal structure distribution of the oil-gas separator by using the lubricating oil pressure of the engine, thereby improving the oil-gas separation efficiency. Moreover, the oil-gas separator has an adjusting function on the pressure of a crankcase in the engine, ensures that the pressure of the crankcase is stable and does not change violently, and reduces the sealing pressure of each sealing surface in the engine.
Embodiments of the present invention also provide a vehicle including an engine as described above.
In the embodiment of the invention, the automobile adopting the engine is suitable for various load working conditions, can achieve the purpose of improving the oil-gas separation effect, and meets the emission requirement of the automobile.
