Description
Technical field
The utility model is related to automotive engine applications, especially a kind of engine gas-oil separator.
Background technology
Gs-oil separator has important shadow as the necessary function component of crankcase ventilation system to engine performance and discharge
Ring.The oil-gas separation structure for gasoline engine of in the market is still based on baffle-type and cyclone type, but these structures are difficult to meet increasingly tight
Severe emission request.When droplet diameter is in below 5um, especially between 0.3~1 μm, traditional gas oil separation structure without
Method is by the gentle separation of oil.So to improve the oil-gas separation efficiency of this scope, it is necessary to use more excellent structure type.
When engine works, the high pressure combustion mixture and burnt gas of combustion chamber can more or less pass through piston group
Gap between cylinder is leak into crankcase, causes gas blowby.The composition of gas blowby is unburned fuel vapor, vapor and waste gas
Deng this can dilute machine oil, reduce the performance of machine oil, accelerate aoxidizing, going bad for machine oil.Condensation of moisture, can shape in machine oil
Into greasy filth, clogged oil line；Sour gas in waste gas is mixed into lubricating system, can cause the corrosion of engine part and accelerate mill
Damage；Gas blowby can also make the hypertonia of crankcase and destroy the sealing of crankcase, be lost in engine oil leakage；Part gas blowby can be lost in
Into air, aggravate the pollution of automobile emission.To prevent crankcase pressure too high, extend machine oil useful life, reduce part
Abrasion and corrosion, prevent engine oil leakage, it is necessary to carry out crankcase ventilation.Gs-oil separator must as crankcase ventilation system
Functional unit is wanted, the stability that engine works is had a major impact with security.Therefore, opened in crankcase ventilation system design
During hair, design and the performance study of gs-oil separator are one of most important links.
With domestic automobile industry develop rapidly and people are on the increase to automobile demand amount, in September, 2011,
China's automobile guarantee-quantity has broken through 100,000,000 high pointes.The thing followed is that a series of of the ever-increasing automobile belt of quantity ask
Topic, wherein topmost is the environmental pollution that automobile emission is caused.This promotes the whole world to propose the emission problem of automobile
More stringent requirement.And " the standard of state six ", even more to the tight of automobile industry instantly that China will carry out in the end of the year 2016
High challenge.
Prior art：
Existing oil-gas separator structure is mainly two kinds of baffle-type (also referred to as labyrinth type) and cyclone type.
1st, labyrinth type oil-gas separator
As shown in figure 1, labyrinth type oil-gas separator is also referred to as baffle-type gs-oil separator, its operation principle is in gaseous mixture
Flow direction on the baffle plate in similar labyrinth is installed to obstruct gaseous mixture, while also increasing the effective travel of air-flow.Baffle plate master
It is forcibly changing air current flow direction to act on, and makes oil droplet in the presence of inertia force with collision with wall and staying on wall,
So as to reach the purpose of Oil-gas Separation.
Labyrinth type oil-gas separator to be mainly characterized by service life length, the pressure loss small, cheap, and can collect
Into in engine valve cover, therefore it is widely used.But labyrinth type oil-gas separator separative efficiency is not high, can not have
The less olesome of effect separation, it is difficult to meet increasingly harsh emission request, therefore simple labyrinth type oil-gas separator
Gradually decreased with the time.
2nd, cyclone type oil-gas separator
As shown in Fig. 2 the operation principle of cyclone type oil-gas separator, which is gaseous mixture, passes through helical intake or tangential gas
Road enters separator interior, and gaseous mixture rotates in separator, so as to produce point that centrifugal force realizes oil droplet and gas
From.
3rd, labyrinth adds the isolating construction of cyclone type
As shown in figure 3, for the structure of cylinder head cover lid, cyclone type and mazy combination can be carried out, labyrinth is combined
The advantage of formula and cyclone type, but higher is required to border.
No matter labyrinth type or cyclone type oil-gas separator, be all to be attached to oil droplet by the gravity or inertia force of oil droplet
On gs-oil separator wall, so as to realize the separation with gas.But for small olesome, fly in gas, in the state of mist of oil,
This separating resulting just can not be separated realizing.
Utility model content
The utility model aims to solve the problem that above mentioned problem there is provided a kind of engine gas-oil separator, in gaseous mixture
Larger oil droplet be relatively good separation, but small oil droplet can be present in gaseous mixture so that one kind is vaporific, it is difficult to divide in a conventional manner
From engine of the present utility model can both realize the separation of the larger oil droplet in gaseous mixture well with gas-oil separator, again
More short grained oil droplet can be made with qi leel from overall to require low to border, the technical scheme of use is as follows：
A kind of engine gas-oil separator, it is characterised in that including：Labyrinth type air flue, adsorption cotton and plastics gear
Plate, the adsorption cotton is arranged at the gas outlet of labyrinth type air flue, with from the air inlet of labyrinth type air flue to labyrinth type air flue
Gas outlet is that the plastic dam is fixedly installed on the rear of adsorption cotton and is spaced a distance with adsorption cotton from front to back,
The lower section of the adsorption cotton has the oil-returning structure being connected with crankcase.
On the basis of above-mentioned technical proposal, baffle plate is provided with front of the adsorption cotton, the baffle plate setting is in labyrinth type
At the gas outlet of air flue, several apertures are offered on the baffle plate.
On the basis of above-mentioned technical proposal, the labyrinth type air flue mainly by air flue main body and is arranged at air flue body interior
Some pieces of maze boards composition, the maze board be arranged in air flue main body cause gaseous mixture S-shaped flowing in air flue main body.
The utility model has the following advantages that：The larger oil droplet in gaseous mixture is separated by labyrinth type air flue, utilized
Porous adsorption cotton is separated to the small oil droplet in gaseous mixture, using foraminate oil baffle is opened up, because gaseous mixture is small
The drastically change of area at hole, can sharply increase the flow velocity through the gaseous mixture of aperture, gaseous mixture is collided adsorption cotton, can enter
One step improves separative efficiency；Larger oil droplet can be separated, small oil droplet can be separated again, good separating effect, while whole
Body requires low to border, that is, occupies little space.
