Description
Technical field
The utility model relates to a kind of gas and oil separating plant, in particular to a kind of oil-gas separating device of internal combustion engine.
Background technique
At work, since lubricating oil flows through workpiece, lubricating oil temperature increases and is mingled with a large amount of bubbles to internal combustion engine,
A large amount of air-fuel mixture gas can be generated in the case by flowing back to after grease-box, when piston downlink, so that air pressure liter in grease-box
Height, in safe range, oil tank need to communicate pressure control with atmosphere in order to keep in grease-box, be often provided with breather valve
The pressure in grease-box is controlled, by outside extra air-fuel mixture gas removal of lubricant case, in the air-fuel mixture gas of discharge
There are a large amount of lubricating oil, a large amount of lubricating oil is discharged with gas and is lost, existing interior in order to reduce rate of lubricating oil consumption
Combustion engine, gas and oil separating plant are arranged in outside internal combustion engine, and the high-temperature oil gas mixed gas come from grease-box enters oil gas point
Oil-gas Separation is carried out from room, the lubricating oil separated flows back to grease-box, and the gas after separating is discharged to outside grease-box.
However, this external gas and oil separating plant is there are two defects, first is that being limited by exterior space, gas and oil separating plant is generally done
It is smaller, oil gas separation is bad；Second is that gas and oil separating plant sealing easily goes wrong, lubricating oil is leaking directly into internal combustion
Outside machine, formed lubricating oil leakage the phenomenon that.
Utility model content
The purpose of the utility model is to overcome the external gas and oil separating plant in the presence of the prior art is smaller, oily
The problem of gas inferior separating effect and lubricating oil leakage, provides a kind of built-in oil-gas separating device of internal combustion engine.
In order to realize above-mentioned purpose of utility model, the utility model provides following technical scheme:
Oil-gas separating device of internal combustion engine, including Oil-gas Separation component, the Oil-gas Separation component are arranged in internal combustion engines,
The Oil-gas Separation component is arranged along grease-box to cylinder cap direction from the bottom to top, is disposed with air inlet on the Oil-gas Separation component
Hole, gas vent and oil return hole, the mixed oil and gas from grease-box can enter the Oil-gas Separation component through the air inlet,
Gas after separation is discharged through gas vent by the opening on cylinder cap, and the lubricating oil after separation flows into grease-box by oil return hole.
Further, the Oil-gas Separation component includes the first Oil-gas Separation room, is disposed with strainer in the first Oil-gas Separation room,
The air inlet of first Oil-gas Separation room is communicated with grease-box, the first oil return hole and the grease-box phase of the first Oil-gas Separation room
It is logical.What is generated has the technical effect that mixed oil and gas under the action of strainer, and most of lubricating oil condenses in screen surface, then exists
The first Oil-gas Separation room lower part is collected in gravity and case under suction function, grease-box is flowed back to by the first oil return hole, is separated
Grease-box is discharged through gas vent in gas afterwards.
Further, the Oil-gas Separation component further includes the second Oil-gas Separation room, and the second Oil-gas Separation room is located in cylinder cap,
It is disposed with breather valve on second Oil-gas Separation room, the second oil return hole, the second Oil-gas Separation room and are disposed on the breather valve
One Oil-gas Separation room is communicated by the breather valve.Breather valve is the prior art, and details are not described herein.The technical effect of generation
Be: the air pressure that breather valve controls in grease-box is kept in allowed limits, at the same air-fuel mixture gas by breather valve and
Secondary separation is carried out when the second Oil-gas Separation room, the small droplet of lubricating oil is condensed into wall adsorption cooling, through the on breather valve
Two return ports flow into the first Oil-gas Separation room.
Further, the strainer is made of the zinc-plated wire mesh in surface.The gold for having the technical effect that surface is zinc-plated generated
Category silk can resist the corrosion of high-temperature oil gas mixed gas, meanwhile, zinc oxide is generated after the zinc coat oxidation on surface, is had outstanding
Adsorptivity, the lubricating oil in fuel-air mixture can be adsorbed on to the maximum extent on the surface of strainer.
Compared with prior art, the utility model has the beneficial effects that
1, oil gas separation is more preferable.It is limited by internal combustion engine exterior space, existing external gas and oil separating plant volume
Smaller, the strainer volume for playing main centrifugation is also smaller, causes oil gas separation undesirable；The utility model will be oily
Built in air separation, when not increasing outer dimension, take full advantage of internal combustion engines using space, oil gas point
Being made from device can be bigger, and correspondingly strainer volume is also bigger, and oil gas separation is more preferable.
2, machine oil leakage is solved the problems, such as.Existing external gas and oil separating plant, after being damaged due to sealing ring often
The problem of meeting directly reveal lubricating oil outside internal combustion engine, and the utility model is built-in due to using, and be not in lubricating oil leakage.
Detailed description of the invention:
Fig. 1 is the outline drawing of internal combustion engine
Fig. 2 is the A-A cross-sectional view of internal combustion engine
Fig. 3 is the explosive view of internal combustion engine
Marked in the figure: 1- cylinder cap, the second Oil-gas Separation of 2- room, 3- breather valve, the first Oil-gas Separation of 4- room, 5- strainer, 6-
Sealing ring.
Specific embodiment
The utility model is described in further detail below with reference to test example and specific embodiment.But it should not be by this
The range for being interpreted as the above-mentioned theme of the utility model is only limitted to embodiment below, all to be realized based on the content of the present invention
Technology belongs to the scope of the utility model.
Such as Fig. 1-3, oil-gas separating device of internal combustion engine, including the first Oil-gas Separation room 4 and the second Oil-gas Separation room 2.First
Strainer 5 is disposed in Oil-gas Separation room 4, strainer 5 is made of the zinc-plated wire mesh in surface, and strainer 5 can be rolled up by gauze element
It makes, the first Oil-gas Separation room 4 is made of the cavity of cylinder interior and sealing ring 6, and 4 lower disposed of the first Oil-gas Separation room has
Oil return hole, the lubricating oil separated directly flow back to grease-box by the first oil return hole；Second Oil-gas Separation room 2 is by cylinder cap 1
On cavity and sealing ring 6 constitute, be disposed with breather valve 3 on the second Oil-gas Separation room 2, the second oil return be disposed on breather valve 3
Hole, the second Oil-gas Separation room 2 and the first Oil-gas Separation room 4 are communicated by breather valve 3, the row of being disposed on the second Oil-gas Separation room 2
Cylinder cap is discharged in gas after separation by stomata.
When work, such as Fig. 2, the high-temperature oil gas mixed gas that grease-box generates through at B from the first Oil-gas Separation room 4 into
Stomata enters, the first time Oil-gas Separation through filter screen 5, and lubricating oil is returned from the first oil return hole of 4 bottom of the first Oil-gas Separation room
Flow into grease-box；Gas after separating for the first time enters the second Oil-gas Separation room 2 through breather valve 3, in the second Oil-gas Separation room 2
Wall cooling condense into the small droplet of lubricating oil, when forming negative pressure in oil tank, the lubricating oil in the second Oil-gas Separation room 2 exists
Under suction function, it is inhaled into the first Oil-gas Separation room through the second oil return hole on breather valve 3, simultaneously because breather valve internal gas flow
Channel is bending channel, and parts of lubricating oil is adsorbed in channel surface and also functions to certain Oil-gas Separation effect.After secondary separation
Gas by cylinder cap 1 outlet C be discharged.
