According to the invention, the elasticity of the elastic sheet 42 can fluctuate back and forth under the impact of the mixed oil gas, the oil gas is separated by utilizing the difference of inertia of gas and engine oil particles, and the included angle between the elastic sheet 42 and the main channel 41 can be adjusted, so that the pressure loss can be properly reduced and the separation efficiency of the mixed oil gas can be improved.
Further, a partition plate 11 is arranged inside the housing 1 to divide the housing 1 into an oil chamber 12 located below and an air chamber 13 located above, the main passage 41 penetrates through the partition plate 11 to communicate the bottom of the main passage 41 with the oil chamber 12, the top of the main passage 41 with the air chamber 13, the mixed oil and gas inlet 10 with the oil chamber 12, and the gas outlet 30 with the air chamber 13.
In one embodiment, the shape of the main passage 41 may be circular, and the diameter of the bottom of the main passage 41 is smaller than the diameter of the top of the main passage 41, so that the mixture can be prevented from flowing into the main passage 41 in a large amount.

Fig. 5 is a schematic cross-sectional view taken along a sectional line a-a in fig. 2. As shown in fig. 5, in one embodiment, the oil chamber 12 includes an annular passage 121 disposed corresponding to the main passage 41, so that the mixture oil flowing in from the mixture oil inlet 10 flows along the annular passage 121, thereby pre-separating a part of the oil particles in the mixture oil, and the pre-separated mixture oil flows into the main passage 41. Here, the annular channel 121 can be regarded as a centrifugal separation channel (preseparation). It can be understood that the annular channel 121 in the oil chamber 12 of the present invention plays a role in pre-separating the oil-gas mixture, the oil-gas mixture flows in the annular channel 121 in a rotating manner, and continuously collides with the inner wall of the annular channel 121, so as to separate the large-particle engine oil molecules, then the pre-separated oil-gas mixture flows into the main channel 41, the oil-gas mixture is finely separated by the elastic sheet 42 into the small-particle engine oil molecules, and the elastic sheet 42 can also play a role in adjusting the operating state of the separation mechanism 40. Specifically, when the number of the separating mechanisms 40 is multiple, the number of the annular channels 121 in the oil chamber 12 is correspondingly multiple, the plurality of annular channels 121 are connected in series, and the inlets of the annular channels 121 are all arranged on the side of the annular channels 121, so that the mixed oil gas can enter along the side wall of the annular channels 121, and the inlets of the annular channels 121 are all connected with the mixed oil gas inlet 10.
The passive separator is difficult to match with a large-displacement engine, on one hand, the low-rotating-speed low-load separation efficiency is improved, and the oil-gas separation assembly 100 is required to be designed into a small separation channel, so that the pressure loss of the oil-gas separation assembly 100 under the high-rotating-speed high-load working condition is large, and the pressure of an engine crankcase is large; on one hand, if the separation channel of the oil-gas separation assembly 100 is enlarged, the pressure loss is reduced when the flow rate is high, the separation efficiency is too low in a low-rotating-speed and low-load state, and more small engine oil particles enter a combustion chamber through a supercharger, so that the service life of the supercharger is influenced, and even abnormal combustion is caused. The invention can control the gas flow and separate the mixed oil gas by adjusting the included angle between the elastic sheet 42 and the main channel 41, the pressure loss is proper, the pressure of the crankcase of the engine can be controlled, the separation efficiency under high and low load working conditions can be considered, the separator under the full working condition of the engine can be kept in the optimal state, the content of the escaping engine oil in the ventilation device of the crankcase can be reduced, the impeller of the supercharger can be protected, the tendency of combustion and detonation can be improved, and the particulate matters in the exhaust gas can be reduced.
Furthermore, the invention can be suitable for the condition of excessive wear or abnormal increase of air leakage of the engine by adjusting the included angle between the elastic sheet 42 and the main channel 41, and the engine is not instantly scrapped due to the fact that a large amount of engine oil is sprayed out. In addition, the maximum flow range of the separator can be set high because the flow interval limit value can be avoided to a certain extent (depending on the engine arrangement space), namely, the range of the included angle between the elastic sheet 42 and the main channel 41 is increased.
Further, the air outlet 30 in the present invention includes a first air outlet 31 and a second air outlet 32, the first air outlet 31 is connected to an intake manifold of the engine, and the second air outlet 32 is connected to the supercharger. Specifically, when the engine is in a medium-low load condition, the gas separated by the oil-gas separation assembly 100 directly enters the intake manifold of the engine through the first gas outlet 31. When the engine is in a high-load working condition, the gas separated by the oil-gas separation assembly 100 enters the front end of the supercharger through the second gas outlet 32. And, a pressure regulating valve 60 for controlling the flow rate of the gas is further provided in front of the gas outlet 30. One-way valves (not shown) are arranged between the pressure regulating valve 60 and the first air outlet 31 and the second air outlet 32, so that gas backflow can be avoided, and unidirectional flow of gas in the pipeline is ensured.
In another embodiment, the oil-gas separation assembly 100 further comprises an oil storage chamber 70 disposed between the oil chamber 12 and the oil return port 20 for storing separated oil to facilitate the accumulation and precipitation of separated oil droplets. A return valve (not shown) is disposed between the oil storage chamber 70 and the return port 20 to control the connection and disconnection between the oil storage chamber 70 and the return port 20. In addition, the oil return port 20 can be recycled through an oil return pipeline and an oil pan of the engine.
Further, the oil-gas separation assembly 100 further includes a collection device 14 and a control device 50 connected to the elastic sheet 42, wherein the collection device 14 is disposed at the mixed oil-gas inlet 10 for detecting the flow rate of the mixed oil-gas. The control device 50 is used for adjusting an included angle between the elastic sheet 42 and the main channel 41 according to the flow after receiving the flow of the mixed oil gas sent by the collecting device 14.
In a preferred embodiment, the number of the separating mechanisms 40 is three, three separating mechanisms 40 are arranged in parallel, the number of the annular channels 121 is three, and three annular channels 121 are arranged corresponding to three separating mechanisms 40. Specifically, the elasticity of the elastic pieces 42 on the three separating mechanisms 40 may be set to be different.
Further, the control device 50 is configured to control the elastic sheet 42 of one of the three separating mechanisms 40 to define an included angle with the main channel 41 when the flow rate is lower than the first preset flow rate, so as to be in an open state, and control the elastic sheets 42 of the remaining two separating mechanisms 40 to be closed with the main channel 41, so as to be in a closed state; and when the flow is higher than a second preset flow, the elastic sheets 42 of the three separating mechanisms 40 are controlled to be in an open state, wherein the second preset flow is larger than the first preset flow. In one embodiment, the adjustable range of the included angle is 0 to 45 °.
The invention also provides a vehicle equipped with an oil-gas separation assembly 100 according to any of the embodiments described above. The oil and gas separation assembly 100 need not be described in detail herein.
According to the invention, when the engine crankcase is in a small flow state, mixed oil and gas in the crankcase enters the oil-gas separation assembly 100 through the mixed oil-gas inlet 10 and then enters the centrifugal separation device through the inlet of the annular channel 121 (centrifugal separation channel) to separate large engine oil particles, because the pressure loss of the channel is small in the small flow state, two elastic sheets 42 in the three separation mechanisms 40 are in a closed state, only one elastic sheet 42 is in an open state, and the same result is that all gas enters the gas cavity 13 through the included angle between the opened elastic sheet 42 and the corresponding main channel 41, so that the separation mechanisms 40 work in the best state to improve the separation efficiency. Meanwhile, the opened elastic sheet 42 is opened at different angles along with the different gas flow rates, the separation efficiency and the pressure loss of different flow rates in a small flow rate state are adjusted, the fluctuation of the elastic sheet 42 is a good fine separation structure, the small oil particles can be rebounded to the centrifugal separation device by utilizing the different inertia of the gas and the oil particles, the gas escapes to the elastic sheet 42 and then collides with the annular baffle 43 again, and the separated fresh gas enters the gas inlet manifold through the one-way valve and the first gas outlet 31 in sequence after the gas flow rate is adjusted by the pressure adjusting valve 60.
When the engine crankcase is in a large flow state, mixed oil and gas in the crankcase enters the oil-gas separation assembly 100 through the mixed oil-gas inlet 10 and then enters the centrifugal separation device through the inlet of the annular channel 121 (centrifugal separation channel) to separate large engine oil particles, because the flow is large, the pressure loss of the centrifugal separation device is overlarge, at the moment, the elastic sheets 42 of the three separation mechanisms 40 are all opened, part of gas flows out through the other two separation mechanisms 40, so that the other two separation mechanisms 40 work in the best state to improve the separation efficiency, on one hand, the pressure loss of the first separation mechanism 40 can be prevented from being rapidly increased due to the fact that the air leakage amount exceeds a certain limit, and on the other hand, the elastic sheets 42 in the first separation mechanism 40 are prevented from being damaged by impact. Meanwhile, because the elastic sheets 42 on the two separating mechanisms 40 are opened at different angles along with different flow rates, the separating efficiency and the pressure loss of different flow rates can still be adjusted, the small oil drop particles are rebounded to the centrifugal separating mechanism 40 by utilizing the fluctuation of the elastic sheets 42 and the different inertia of gas and oil drop particles, the gas collides the annular baffle 43 again after escaping to the elastic sheets 42, and the separated fresh gas passes through the pressure regulating valve 60 to adjust the gas flow rate and then sequentially passes through the one-way valve and the gas outlet 30 to enter the front end of the supercharger.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
