Abstract
The invention provides a cyclone type oil-gas separator of an engine. The separator comprises a conical cavity body, wherein the side wall of the upper part of the conical cavity body is provided with a mixed oil-gas inlet tube, the top part of the conical cavity body is provided with a gas discharge opening, and the bottom part of the conical cavity body is provided with an oil return opening; and the inner wall of the conical cavity body is provided with a spiral type maze separation path from the top to the bottom, the spiral type maze separation path is a protruding strip forming the surface of the inner wall of the conical cavity body and spirally goes down on the inner wall of the conical cavity body, and the spiral type maze separation path is of a discontinuous type. The separator adopts a structure of the combination of the conical cavity body and the spiral type maze, so that under the same manufacturing process conditions, the separator has the advantages of improving the wall collision effect when the oil and the gas centrifugally rotate, improving the adhesive capability of the oil and the gas, reducing the amount of the mixed gas entering a combustion chamber of the engine, lowering emission, and reducing the consumption of engine oil.
Description
Technical field
The present invention relates to automobile engine crankshaft case aeration technology field, be specifically related to a kind of cyclone type oil-gas separator.
Background technique
Petrol engine is in the compression stroke process, and the mixed with little amount gas in the cylinder is by piston ring and cylinder interporal lacuna, the ring gap, and the crankcases that bleed such as valve and valve guide bushing gap, major part is the gasoline that does not fire, discharging shows as hydrocarbon.According to the national legislation requirement, this mixed gas can not enter atmosphere environment, but if not with its processing, it easily makes machine oil precipitate, and influences the greasy property of machine oil, and a large amount of mixed gass are assembled also can cause the crankcase pressure rising, causes sealing configuration leakages such as oil sealing.Ventilation system is exactly the importing cylinder combustion that this mixed gas is an amount of, under the prerequisite that does not influence performance, handles this mixed gas.
Traditional cyclone type oil-gas separator as shown in Figure 4, it adopts single circular cone cavity 1 design, the inner wall smooth of circular cone cavity 1 utilizes the rotary centrifugal force of gas that oil gas is separated.It is to the Oil-gas Separation effect, and the attached wall energy power of oil droplet is less.Therefore, still there is a large amount of oil gas can enter in the gas handling system, causes the valve carbon distribution serious, influence the performance of motor.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, propose a kind of cyclone type oil-gas separator of motor, adopt the circular cone cavity, reach the purpose that improves Oil-gas Separation in conjunction with the spirality labyrinth structure.
Technological scheme of the present invention is as follows:
A kind of cyclone type oil-gas separator of motor, it has the circular cone cavity, is provided with mixed oil and gas and goes into pipe on circular cone cavity upper portion side wall, and relief opening is arranged at the top, and return opening is arranged at the bottom.It is characterized in that on described circular cone cavity inner wall, being provided with the spirality labyrinth from top to bottom and separate the road, it is the raised line that is formed on circular cone cavity inner wall surface that the road is separated in described spirality labyrinth, shape is descending in the shape of a spiral on the circular cone cavity inner wall, and to separate the road be discontinuous in the spirality labyrinth.
Further, separate between the road in the spirality labyrinth adjacent in the left and right sides, and be formed with the oil gas data feedback channel from bottom to top along the circular cone cavity inner wall.And described oil gas data feedback channel evenly distributes along the circumferencial direction of circular cone cavity, and the protrusion height that the road is separated in the spirality labyrinth also is to become short from top to bottom gradually.
The present invention adopts the circular cone cavity in conjunction with the spirality labyrinth structure, adopting under the same fabrication process condition, because being set, the spirality labyrinth separates the road structure, improved the rebuffed effect when oil gas is centrifugal to be rotated, can improve the adhesive ability of oil gas, better reduce mixed gas and enter in the firing chamber of motor, reduce discharging, reduce oil consumption.Compare with other similar cyclone type oil gas separation structure, this structure is only separated the road by increase the spirality labyrinth on the awl wall of garden, has just improved the separating property of oil gas, and cost does not almost increase.

Fig. 2 is that traditional vortex type oil gas separates schematic representation;
Fig. 3 is the A-A sectional view of Fig. 2.
Fig. 4 is the structural representation of existing deaerator.
Embodiment
Describe structure of the present invention in detail below in conjunction with accompanying drawing:
Referring to Fig. 1 and Fig. 2, this cyclone type oil-gas separator includes a circular cone cavity 1, the same with existing similar deaerator, on the upper portion side wall of circular cone cavity 1, be provided with mixed oil and gas and go into pipe 4, relief opening 6 is arranged at the top, return opening 5 is arranged at the bottom, and they are all combined by plastics molding process, and whole cyclone type oil-gas separator is connected engine cylinder by bolt and covers.Different is that the inwall of circular cone cavity 1 is not smooth, is provided with the spirality labyrinth from top to bottom and separates road 2 on circular cone cavity 1 inwall, forms the spiral labyrinth structure.Road 2 is separated for being formed on the raised line of circular cone cavity 1 inner wall surface in the spirality labyrinth, shape is descending in the shape of a spiral on circular cone cavity 1 inwall, and to separate road 2 be discontinuous in the spirality labyrinth.
And, the layout that road 2 is separated in the spirality labyrinth also has requirement, referring to Fig. 3, to separate between the road 2 in adjacent spirality labyrinth in the left and right sides, and form oil gas data feedback channel 3 from bottom to top along circular cone cavity 1 inwall, and this oil gas data feedback channel 3 preferably will evenly distribute along the circumferencial direction of circular cone cavity 1.In addition, in order to reach better oil gas separation, the protrusion height that the spirality labyrinth can also be separated road 2 is designed to become gradually short form from top to bottom.
When motor is in running state, the mixed oil and gas 7 of engine crankcase can pass through cylinder body, the cylinder cap ventilating hole enters valve mechanism cover and goes into pipe 4 inflow cyclone type oil-gas separators by mixed oil and gas, because circular cone cavity 1 separates 2 existence with the spirality labyrinth, mixed oil and gas 7 produces the spiral rotation of oil gas 8 in deaerator, in the rotary course of oil gas 8, separate 2 contact generation oil droplets 9 with the inwall of circular cone cavity 1 and outstanding spirality labyrinth, oil droplet 9 is downwards by in the return opening 5 inflow engine oil pans, and the gas 10 after separating then enters to enter in the motor at last in the intake manifold by relief opening 6 under the guiding of oil gas data feedback channel 3 and burns.
