Description
Technical field
The invention belongs to Oil-gas Separation technical fields, and in particular to a kind of tree-shaped leaf fat drive formula voltage adaptive controlling engine oil
Air separation.
Background technique
The high-temperature fuel gas that engine generates at work can be scurried into crankcase by the gap between piston group and cylinder,
Cause gas blowby.The ingredient of gas blowby is unburned fuel vapor, vapor and exhaust gas etc..Water vapor condensation dilutes machine in machine oil
Oil reduces the service performance of machine oil；Sulfur dioxide in exhaust gas encounters air oxidation and generates sulfuric acid, and the oxidation of machine oil is accelerated to become
Matter will lead to the corrosion and accelerated wear test of engine part；Gas blowby can also make the hypertonia of crankcase and destroy crankcase
Sealing, is lost engine oil leakage；Accelerate the aging of machine oil, reduces reliability.Therefore, it is necessary to using crankcase ventilation system to altering
Gas is controlled.Gas blowby can carry a large amount of oil gas, machine oil is caused to be lost, deteriorate simultaneously when flowing through crankcase ventilation system
Discharge, it is therefore necessary to oil gas be separated, machine oil loss is reduced.By gs-oil separator being integrated in valve mechanism cover come to hair
The oil gas that motivation excludes is separated, and traditional valve mechanism cover can only carry out single separation, and effect can not reach expected.
Such as a kind of Chinese utility model patent " valve mechanism cover " of Publication No. CN205559013U, including valve mechanism cover sheet
Body, cylinder head cover body inside are formed with oil gas pre-separation chamber, and the oil gas pre-separation chamber is equipped with pre-separation air inlet and in advance
Gas outlet is separated, is successively arranged from the pre-separation air inlet to the pre-separation gas outlet along vertical in oil gas pre-separation room
The spaced multiple lateral partitions in direction and in the horizontal direction be in the spaced multiple longitudinal baffles of labyrinth type, lateral partitions
The mazy gas channel for being connected to pre-separation air inlet and pre-separation gas outlet is formed between longitudinal baffle, and in cylinder head
Cover lateral wall is integrated with gs-oil separator.By the above content it can be found that valve mechanism cover oil gas pre-separation in the prior art
Core is the mazy gas channel formed between lateral partitions and longitudinal baffle, but its single layer structure Oil-gas Separation ability
Difference can not separate fine oil droplets, and when having in separator pressure-difference fluctuation, not can guarantee the stability of flow velocity, also can not
It realizes passive type separation and active isolated combination, is unable to satisfy the requirement of the discharge of engine state six.
Such as the Chinese invention patent " active gs-oil separator " of Publication No. CN104265402B, pass through extreme pressure lubricant
Driving is a kind of oily drive formula active separator, can carry out active separation to the gas mixture in crankcase, but only with master
Dynamic formula separator is unable to satisfy six discharge standard of state, can not also be classified processing super large oil droplet, larger oil droplet and fine oil droplets.
It is interior such as the Chinese invention patent application " oil and gas separating system built in valve mechanism cover " of Publication No. CN108049937A
Set gs-oil separator, comprising: housing ontology and the labyrinth cavity and bottom cover that the housing ontology side is set, the labyrinth chamber
One end of body is provided with the outgoing gas connection tube extended to outside housing, and top offers respirator socket；It is equipped in the labyrinth chamber body
Coarse filtration orifice plate, winding type rectifier structure, refined filtration orifice plate and every position plate.By the above content it can be found that cylinder in the prior art
Housing oil-gas pre-separation device is equipped with coarse filtration orifice plate and winding type rectifier structure, can be used for Oil-gas Separation, but super large oil droplet
The oil droplet of 10um (diameter be greater than) is easy to mix with larger oil droplet (referring to that droplet diameter is 2~10um), and do not have oil droplet absorption with
Diversion effect, the droplet diameter that will lead into refined filtration orifice plate is still very big, (refers to that droplet diameter is 0.1 for handling small oil droplet
~2um) there is very big influence；Winding type rectifier structure disclosed in the prior art can not solve gas mixture and touch at a high speed
Oil droplet second-time breakage (collision is splashed) problem generated when hitting, oil droplet can not adsorb back after flowing through collision winding type rectifier structure
It receives, can still be exported as gas mixture flows to, separative efficiency is low.
Summary of the invention
It is an object of the invention to overcome the defect of the above-mentioned prior art, a kind of new partition gas drive formula engine oil is provided
Air separation can be classified separation super large oil droplet, larger oil droplet and fine oil droplets, and separative efficiency is high, moreover it is possible to solve oil droplet
The problem of adsorption recovery and collision are splashed also does not need periodic maintenance replacement filter core, can be achieved at the same time passive type and active
Formula separation；Additionally it is possible to which according to separator internal pressure, self adaptive control flow velocity promotes separative efficiency, is able to satisfy state six
Engine calls.
The purpose of the present invention is what is be achieved through the following technical solutions:
The present invention provides a kind of tree-shaped leaf fats to drive formula voltage adaptive controlling oil-gas separating device of engine, comprising: is mounted on
