Description
Technical field
The utility model belongs to technical field of automobile engine, specifically a kind of cylinder cover of engine gas and oil separating plant.
Background technique
Motor cylinder head cover be a kind of for canned motor crankcase, be positioned at a kind of engine part above motor rockshaft, be otherwise known as rocking arm cover cap.The design of current most of petrol engine cylinder head covers be all common labyrinth or rare filter screen to be separated the machine oil in crankcase in mixed gas, thus reach the object of controller oil consumption and protection of the environment.But the design of this labyrinth or rare filter screen is partially simple, and oil gas separation is not too good, does not very adapt to the needs of positive crankcase ventilation (PCV) technology.Even if increase oil gas baffle more, the resistance that in cylinder head cover, oil gas advances also can be made to strengthen, well can not keep the pressure in crankcase, also make design thicken.Therefore, in cylinder head cover, the reliability of Oil-gas Separation and simplicity seem particularly important.
Summary of the invention
The purpose of this utility model is to provide a kind of cylinder cover of engine gas and oil separating plant.With the technical problem such as poor for the oil gas separation existing for current art, working life is short, and provide that a kind of oil gas separation is good, the cylinder cover oil-gas separating device of reliable operation.
The purpose of this utility model realizes like this, it includes cylinder head cover housing, the oiled-plate method be connected with cylinder head cover housing, the oil-gas separating plate be connected with oiled-plate method, suction tude, steam outlet pipe, is characterized in that: on the cylinder head cover housing near suction tude, be fixed with air inlet side oiled-plate method assembly, and the cylinder head cover housing near steam outlet pipe is fixed with side oiled-plate method assembly of giving vent to anger; Air inlet side oiled-plate method assembly and side oiled-plate method assembly of giving vent to anger are respectively arranged with overhead gage, lower pedal, oil-gas separating plate, air inlet side oiled-plate method assembly and side oiled-plate method assembly of giving vent to anger also are provided with oil trap, have oilhole in oil trap end; Described oil-gas separating plate is distributed with the Oil-gas Separation hole of interlaced setting.
For improving oil gas separation, air inlet side oiled-plate method assembly and side oiled-plate method assembly of giving vent to anger at least are provided with two oil-gas separating plate.
Working principle is: be provided with the gas-oil separation baffle staggered mutually in position, some groups of holes between side oiled-plate method assembly and cylinder head cover, cylinder head cover is provided with suction tude and steam outlet pipe, the alternate gas-oil separation baffle be interspersed in position with holes is provided with between described suction tude and steam outlet pipe, gas enters cylinder head cover inside and air-fuel mixture by suction tude, oil gas is successively by crankcase of entering after the gas-oil separation baffle of air inlet side, oil gas in crankcase successively again through the gas-oil separation baffle of side of giving vent to anger, thus will reach Oil-gas Separation object when leaving crankcase.The baffle means of a kind of hole bit interleave that the utility model designs for gas-oil separation baffle, it effectively can not only carry out Oil-gas Separation, also very significantly on reduce the resistance that oil gas advances, and cheap for manufacturing cost, make simple, oil gas separation is good.
The utility model has the advantages that:
By original entity or change to bilateral with the gas-oil separation baffle in one-sided hole and position, hole is dislocatedly distributed, both alleviated weight, make again oil gas reduce at cylinder head cover internal resistance, the pressure in crankcase more easily keeps.
Due to the practical thin board type punch designs of engine sump tank body gas-oil separation baffle, the edge designs of baffle plate can be made to be cylinder head cover inner chamber profile, thus to ensure the validity of Oil-gas Separation.
As Novel oil gas segregating unit, oiled-plate method is designed to two-part, and is fixed by several rivets between cylinder head cover, forms labyrinth channel.Simple, the practical and manufacture cost relative moderate of its structure.
As Novel oil gas segregating unit, described oiled-plate method upper punch is pressed with oil-collecting depression, is provided with oilhole, lays respectively in the middle part of pitman arm shaft and two ends in the most termination of depression.Oil-collecting depression on oiled-plate method can be that the liquid machine oil sticked in labyrinth channel flows back in crankcase more smoothly, and machine oil drops on rocking arm, also can carry out the lubrication of rocking arm.

Embodiment
example 1
As shown in Figure 1, in figure 1 is cylinder head cover housing, suction tude 4 is connected with car load gas handling system, cylinder head cover housing 1 near suction tude is fixed with air inlet side oiled-plate method assembly 2, cylinder head cover housing near steam outlet pipe is fixed with side oiled-plate method assembly 3 of giving vent to anger, air inlet side oiled-plate method assembly 2 and side oiled-plate method assembly 3 of giving vent to anger are respectively arranged with overhead gage, lower pedal, and two oil-gas separating plate, air inlet side oiled-plate method assembly 2 and side oiled-plate method assembly 3 of giving vent to anger also are provided with oil trap, have oilhole in oil trap end; Described oil-gas separating plate is distributed with the Oil-gas Separation hole of interlaced setting.Gas, by suction tude 4 inlet casing housing housing 1, mixes with the oil gas in cylinder head cover housing 1, enters in crankcase after air inlet side oiled-plate method assembly 2 is separated.Steam outlet pipe 5 is connected with engine intake manifold, and the oil gas in crankcase is entered in intake manifold by steam outlet pipe 5 after side oiled-plate method assembly 3 of giving vent to anger is separated.This gas and oil separating plant is air inlet, two-part of giving vent to anger, and directly falls back in crankcase through the isolated machine oil of this device.
As shown in accompanying drawing 2 and accompanying drawing 4-5,2-1 is air inlet side oiled-plate method, oil gas in crankcase is by lower pedal 2-3 and overhead gage 2-2, mix with the air that suction tude enters, successively be separated with oil-gas separating plate 2-5 through oil-gas separating plate 2-4, oil droplet after separation falls into oil trap 2-1-2, and by falling, oilhole 2-1-3 falls in crankcase.
As shown in accompanying drawing 3 and accompanying drawing 4,3-1 is side oiled-plate method of giving vent to anger, and the oil gas in crankcase, by lower pedal 3-3 and overhead gage 3-2, is successively separated with oil-gas separating plate 3-5 through oil-gas separating plate 3-4, oil droplet after separation falls into oil trap 3-1-2, and by falling, oilhole 3-1-3 falls in crankcase.
As shown in annex 4-5, air inlet is connected with cylinder head cover housing by rivet 2-1-4 with 3-1-4 with oiled-plate method of giving vent to anger, oiled-plate method leaves respectively oil gas through hole 2-1-1 and oil gas through hole 3-1-1, oiled-plate method leaves oil trap 2-1-2 and oil trap 3-1-2, store for oil droplet, and fallen in crankcase by the oilhole 2-1-3 and the oilhole 3-1-3 that falls that falls.
As shown in Figure 6, gas-oil separation baffle is provided with Oil-gas Separation hole 3-4-1 and dislocation Oil-gas Separation hole 3-4-2, the two is dislocatedly distributed, and both ensure that the smoothness that oil gas passes through, by the validity meeting Oil-gas Separation, the really simple and effective oil gas separation achieved in crankcase.
Motor is higher to the pressure requirements in crankcase, and the design of thin shape oiled-plate method both ensure that lightweight, facilitated again the design of oil trap, and the oil baffle of dislocation hole design really achieves the unobstructed of Oil-gas Separation and separating effect.
