Description
Technical field
The invention belongs to technical field of internal combustion engines, more particularly, to a kind of crankcase ventilation hole gas and oil separating plant.
Background technology
When engine works, the gas outlet of engine crankcase is connected with the air inlet pipe of engine aspirating system, and making can
Combustion gas combustion, but total some combustion mixture and waste gas Jing piston rings are channeled in crankcase, are channeled in crankcase
Fuel vapor will make machine oil thinning after condensing, performance depreciation.Waste gas is contained within vapor and sulfur dioxide, and Water vapor condensation is in machine
Foam is formed in oil, engine oil supplying is destroyed, this phenomenon is particularly acute in the winter time；Sulfur dioxide meets water generating sulfurous acid, sulfurous
Acid runs into the oxygen in air and generates sulfuric acid, and the appearance of these acidic materials not only makes machine oil go bad, and is subject to can part
Corrosion, also has the danger for causing crankcase explosion when serious.As combustion mixture and waste gas are channeled in crankcase, in crankcase
Pressure will increase, machine oil can ooze out from crankshaft oil seal, crankcase liner etc. and be lost in.Crankcase pressure increases, and makes work
During plug motion, resistance increase, causes engine power loss, engine just avoid or mitigate equipped with crankcase bleeder
Above-mentioned phenomenon.Therefore, the effect of engine crankcase ventilating apparatus is：1. make machine oil keep good oxidation-stabilized performance, prolong
Leader life span of oil, prevents machine oil from going bad；2. crankshaft oil seal, crankcase liner seepage are prevented；3. reduce engine power to damage
Lose；4. in apparent good order and condition, the abrasion and corrosion of reduction parts that each lubrication is secondary are kept；5. pressure in crankcase and outer is kept
Boundary's air pressure is of substantially equal, reduces engine oil leakage and lifts engine performance；6. make mix waste gas be recycled utilization, reduce ring
While border is polluted, the economy of engine is improve.
The content of the invention
In view of this, it is contemplated that proposing a kind of crankcase ventilation hole gas and oil separating plant, to provide a kind of structure letter
Single, oil-gas separation efficiency is high, be not required to the crankcase ventilation hole gas and oil separating plant of increase additional configuration.

From plate, the oil-gas separating plate is whirlpool type structure, the peace of the multiple described oil-gas separating plate installed in each crankcase ventilation hole
Dress angle rotates successively.
Further, two adjacent oil-gas separating plates are not in contact with each other.
Further, the oil-gas separating plate at least two installed on the inwall in each crankcase ventilation hole.
Further, the direction that the oil-gas separating plate is installed is consistent, and concave surface is towards the crankcase ventilation hole
Air inlet.
Relative to prior art, crankcase ventilation hole of the present invention gas and oil separating plant has the advantage that：
(1) crankcase ventilation hole of the present invention gas and oil separating plant, installs oil gas on the inwall of crankcase ventilation hole
Separating plate, does not increase external Oil-gas Separation part, alleviates the pressure of rebreather of engine, and simple structure makes Oil-gas Separation
It is in hgher efficiency, more thorough；Fuel gas after separation enters into engine aspirating system along the gas outlet in crankcase ventilation hole, enters
Row second-time burning, reaches fuel-efficient effect, has saved financial cost.
(2) crankcase ventilation hole of the present invention gas and oil separating plant, oil-gas separating plate are whirlpool type structure, increase table
Area and its contact area with mixed gas, and certain cooling can be carried out to gaseous mixture.
(3) crankcase ventilation hole of the present invention gas and oil separating plant, the angle that each oil-gas separating plate is installed is successively
Rotation, enables the waste gas rotary motion containing machine oil.
(4) crankcase ventilation hole of the present invention gas and oil separating plant, the direction that oil-gas separating plate is installed are consistent, and recessed
Face towards the air inlet in crankcase ventilation hole, can make the liquid pearl condensed in oil-gas separating plate, by gravitational settling, flow back to crankcase
This is in vivo.

Below with reference to the accompanying drawings and in conjunction with the embodiments describing the present invention in detail.
A kind of crankcase ventilation hole gas and oil separating plant, as shown in figure 1, including crankcase bodies 1 and some Oil-gas Separations
Plate 2, is provided with some crankcase ventilation holes 11 inside the crankcase bodies 1, on the inwall in each crankcase ventilation hole 11
Some oil-gas separating plates 2 are installed, do not increase single Oil-gas Separation part, can be logical in the crankcase of any engine
Oil-gas separating plate 2 is set in air holes 11, it is simple, mitigate the pressure of rebreather of engine；
The oil-gas separating plate 2 is whirlpool type structure, increases surface area and its contact area with mixed gas, and can be right
Gaseous mixture carries out certain cooling；The installation of the multiple described oil-gas separating plate 2 installed in each crankcase ventilation hole 11
Angle rotates successively, enables the waste gas rotary motion containing machine oil.
Two adjacent oil-gas separating plates 2 are not in contact with each other, and are conducive to waste gas to pass through.
The oil-gas separating plate 2 at least two installed on the inwall in each crankcase ventilation hole 11, can basis
The actual demand of the length and separation waste gas in the crankcase ventilation hole 11 is freely added, and more hommization, versatility are higher.
The direction that the oil-gas separating plate 2 is installed is consistent, and concave surface is towards the air inlet in the crankcase ventilation hole 11,
The liquid pearl condensed in the oil-gas separating plate 2 can be made, by gravitational settling, is flowed back in crankcase bodies 1.
A kind of operation principle of crankcase ventilation hole gas and oil separating plant is：
Oil-gas separating plate 2 is set in crankcase ventilation hole 11, the anglec of rotation and height of each oil-gas separating plate 2 is adjusted
Degree, enables the air inlet in the waste gas crankcase ventilation hole 11 containing machine oil to be rotating motion to gas outlet, due to liquid, air tightness not
Together, when rotated due to effect of inertia, density big liquid adsorption is in oil-gas separating plate 2, simultaneously because oil-gas separating plate 2
Volute shape, increases surface area, fully can contact with gaseous mixture, and gaseous mixture is carried out it is certain cool, so very
Many oil gas condenses into liquid pearl in oil-gas separating plate 2, finally by gravitational settling, flows back in crankcase bodies 1；What rotation caused
Turbulent flow can accelerate oil droplet to deposit, so as to reach the purpose for separating machine oil and fuel-steam；
As the gas outlet in crankcase ventilation hole 11 is connected with engine aspirating system, the fuel gas after separation is from outlet
Mouth enters engine aspirating system, for second-time burning, pressure that is not only fuel-efficient but also alleviating rebreather of engine.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
