Abstract
The utility model discloses an engine oil-gas separation cylinder head cover which comprises a cylinder head cover body. An oil-gas separation groove is formed in the cylinder head cover body. The engine oil-gas separation cylinder head cover further comprises a labyrinth cover plate used for sealing the oil-gas separation groove. The labyrinth cover plate comprises a cover plate body and a filter plate, wherein the filter plate is fixedly connected with the cover plate body and inserted into the oil-gas separation groove and carries out oil-gas separation. After entering the oil-gas separation groove, the oil and gas collide with components inside the oil-gas separation groove, the bottom and the sides of the oil-gas separation groove and the labyrinth cover plate, and further collide with the filter plate, the collision frequency of oil mist in the oil-gas separation groove is greatly increased, and the walking path of the oil and gas is more complex under the effect of the filter plate. Compared with the prior art, the stroke is significantly lengthened, and the cylinder head cover has the better oil-gas separation effect after being used in an engine, especially a supercharged engine.

Background technique
Valve mechanism cover belongs to a kind of parts of motor, is arranged on the top of engine cylinder cap, for covering cylinder head and arranging wire harness.Motor is in when work, and in crankcase, can there is many mist of oils in camshaft chest, mist of oil can enter in firing chamber by PVC system together with crankcase gas blowby, machine oil can not perfect combustion, with toxic emission, in atmosphere, will have a negative impact to discharge, also can increase consumption of lubricating oil.
For addressing the above problem, someone provides a kind of valve mechanism cover with gas oil separation structure, by labyrinth structure Oil-gas Separation chamber, mist of oil is carried out in valve mechanism cover to Oil-gas Separation, wherein labyrinth structure is arranged in valve mechanism cover, and by cover plate housing, at Oil-gas Separation groove two ends, filler opening and oil outlet are set.But labyrinth structure exhaust passageway of the prior art is very simple, and stroke is shorter, cause Oil-gas Separation not thorough, especially, for supercharged engine, must strengthen Oil-gas Separation, just can avoid mist of oil to enter into final waste gas, affect pressurized effect.On existing basis, for improving the oil gas separation of supercharged engine, can realize by make the labyrinth separation chamber of labyrinth on cover board body, but preparation process is comparatively complicated, cost is higher, be difficult for realizing, and the cover board body of original labyrinth structure need to be replaced, waste material, integral replacing cost is too high.
Therefore, need to improve existing valve mechanism cover, after making it in applying to supercharged engine, there is good oil gas separation.
Model utility content
In view of this, the utility model provides a kind of engine oil gas splitter cylinder housing, after it applies in supercharged engine, has good oil gas separation.
Engine oil gas splitter cylinder housing of the present utility model, comprise cylinder head cover body, in described cylinder head cover body, establish Oil-gas Separation groove, also comprise for sealing the labyrinth cover plate of described Oil-gas Separation groove, described labyrinth cover plate comprise cover board body be fixedly connected with and insert described Oil-gas Separation groove with described cover board body in filter plate to Oil-gas Separation.
Further, described filter plate is two that along cylinder head cover body length direction, are set up in parallel, and on each filter plate, is equipped with filter opening.
Further, the filter opening on described two filter plates shifts to install relatively.
Further, described Oil-gas Separation groove inside is divided into a plurality of Oil-gas Separation chambers that are interconnected by polylith oil baffle, and it is indoor that described two filter plates are placed in two adjacent Oil-gas Separation.
Further, described Oil-gas Separation groove inside is divided into a plurality of Oil-gas Separation chambers that are interconnected by polylith oil baffle, and it is indoor that described two filter plates are placed in same Oil-gas Separation.
Further, described Oil-gas Separation groove is two that along cylinder head cover body length direction, arrange, and labyrinth cover plate correspondence arranges two.
Further, on the two side in each Oil-gas Separation slot length direction, alternate intervals arranges described oil baffle and forms four Oil-gas Separation chambers.
Further, filter opening aperture is arranged on 3-5mm, and pitch-row is set to 4-7mm.
Further, the end in described Oil-gas Separation slot length direction arranges oil gas entrance, and the other end arranges gas outlet and oil outlet.
The beneficial effects of the utility model: engine oil gas splitter cylinder housing of the present utility model, Oil-gas Separation groove is set, and on the cover plate of labyrinth, filter plate is set, filter plate is placed in Oil-gas Separation groove, when oil gas enters after Oil-gas Separation groove, oil gas not only with Oil-gas Separation groove inner member, Oil-gas Separation groove bottom, sidepiece and labyrinth cover plate bump, but also there is further collision with filter plate, greatly increased the collision frequency of mist of oil in Oil-gas Separation groove, and under the cooperation of filter plate, the walking path of oil gas is more complicated, compared with prior art, stroke is significantly improved, make cylinder head cover in adapting to motor, especially after in supercharged engine, there is better oil gas separation, in addition, by the filter plate of further raising oil gas separation is set on the cover plate of labyrinth, without realizing by changing existing labyrinth separation structure, avoided changing the complicated preparation process that labyrinth separation structure is brought, greatly reduce cost of production, and, without to replacing and can realize realization of the present utility model with existing labyrinth separation structure cylinder head cover, avoid the waste of material, saved cost of production.
