Description
Technical field
The utility model belongs to technical field of automobile engine, in particular to there are two the automobiles of gs-oil separator for a kind of tool
Cylinder head cover cap.
Background technique
Automobile engine during the work time, the mixed oil and gas in crankcase, exhaust gas and song in engine combustion room
The oil gas that the lubricating system of the components such as axis connecting rod generates can enter in engine bonnet, pass through the Oil-gas Separation knot inside the cover
Structure realizes Oil-gas Separation, to improve emission effect and reduce consumption of lubricating oil.In the prior art, it is used for automobile engine valve chamber cover
The oil-gas separator structure of lid, have plenty of in maze partition plates be located at Oil-gas Separation space be evenly distributed with multiple partitions, by it is multiple every
Oil-gas Separation space is divided into multiple spaces communicated by plate, so that the flow channel of oil gas is at curved channel, in the mistake of flowing
Oil-gas Separation is realized in journey.Also the Oil-gas Separation hole being staggered is machined on multiple partitions, pass through the Oil-gas Separation being staggered
Hole, forming curves channel carry out Oil-gas Separation.In above structure, the curved channel separation that oil gas is divided into isolation board is directlyed adopt
Oil gas influences the effect of Oil-gas Separation since the gap between partition and bonnet body is larger, and oil gas point is processed on partition
Structure from hole, Oil-gas Separation channel is short, and oil gas separation is also bad, so, all there is Oil-gas Separation in above two structure
The problem that low efficiency, effect are poor, pollution is larger and consumption of lubricating oil is high.
The applicant propose application No. is CN201320845827.3(CN203685410U) it is disclosed that " one kind is used for vapour
The plastic valve chamber cover of car engine ", the left and right sides is each provided with labyrinth baffle S-shaped flow distribution plate and with holes on the baffle of labyrinth
Partition forms multiple curve Oil-gas Separations channel by apertured partition, is provided in cap body and labyrinth baffle S-shaped flow distribution plate
A plurality of S-shaped is collectively formed in corresponding cap body S-shaped flow distribution plate, cap body S-shaped flow distribution plate and labyrinth baffle S-shaped flow distribution plate
Oil-gas Separation channel constitutes compound oil gas split tunnel by a plurality of S-shaped Oil-gas Separation channel and multiple curve Oil-gas Separations channel
The opposite length for extending Oil-gas Separation channel improves Oil-gas Separation by carrying out Oil-gas Separation twice to mixed oil and gas
Effect.But the utility model is that tap hole is directly provided on partition, cannot efficiently separate the oil droplet of small particle range, also
There is a problem of that shunting effect is poor.
Application No. is CN201721865100.6(CN207847791U) utility model disclose " a engine with supercharger
Plastic valve chamber cover ", gas oil separation structure described in the utility model include the first gas oil separation structure and the second oil gas point
From structure；First gas oil separation structure is obliquely installed at an angle with the bonnet body inner wall, includes to be fixedly arranged on
Slot on the bonnet body inner wall, the first gas-oil separation baffle being plugged in the slot, the first gas-oil separation baffle
Several ventholes are equipped with, when mixed oil and gas passes through first gas-oil separation baffle, oil is hit along described first
Gas-oil separation baffle slides to cavity, and gas flow to the second gas oil separation structure, second oil gas by the venthole
Separated structure includes several second gas-oil separation baffles disposed in parallel, second gas-oil separation baffle and the cover
The inner wall of ontology is to be fixedly connected, and second gas-oil separation baffle is wavy shaped configuration, from first gas oil separation structure
The problem of gas out is due to oil-gas separation efficiency can also have certain oil, pass through second gas-oil separation baffle
Shock can further be separated.The utility model discloses the slot being fixedly arranged on the bonnet body inner wall and inserts
The first gas-oil separation baffle being connected in the slot, the utility model be arranged in valve chamber cover body interior there are two oil
Gas separation structure improves oil-gas separation efficiency to play the role of sufficient Oil-gas Separation, and the first gas-oil separation baffle partition with
Bonnet body is connected structure, and still, which is still that mixed oil and gas directly passes through the first gas-oil separation baffle of shock
Oil-gas Separation is carried out with the second gas-oil separation baffle, separation not exclusively, can only also separate bulky grain oil droplet, low separation efficiency point
Poor from effect, gas can also take away the oil of some molecules, cause engine oil carrying quantity big, after burning, increase exhaust emission.
Application No. is CN201720904028.7(CN207212510U) utility model disclose a kind of engine cylinder cover
