Abstract
The utility model is a kind of engine air valve bonnet lid of Oil-gas Separation, oil sealing is uniformly provided among engine air valve bonnet lid, corresponding to be equipped with gas vent in oil sealing side, one end of engine air valve bonnet lid is additionally provided with observation panel, and engine air valve bonnet lid inner wall has multiple vertical baffles；It is equipped with the oily bottom plate of gear under the baffle, the oily bottom plate of gear is equipped with engine air valve bonnet lid oil sealing hole, a cavity is formed between the oily bottom plate of gear and engine air valve bonnet lid inner wall, multiple vertical baffles form labyrinth type oil gas separation structure in cavity, while are designed with partition board on the oily bottom plate of gear.Air-fuel mixture air-flow is parallel to the movement of air-fuel mixture air-flow direction after encountering the partition board on the oily bottom plate of gear in the utility model, the reflux movement in labyrinth type oil gas separation structure simultaneously, larger oil droplet is adsorbed on engine air valve bonnet lid inner wall surface or baffle, smaller oil droplet may then be carried over engine air valve bonnet lid with air-flow, realized using the inertia and shock of oil droplet and detach and collect.
Description
Technical field
The utility model is related to engine air valve bonnet lid, the engine air valve bonnet lids of specifically a kind of Oil-gas Separation.
Background technology
Engine at work, has part burning mixture and combustion product and seals in crankcase by cylinder through piston ring
It is interior.When engine is run at low temperature, it is also possible to there is liquid fuel to leak into crankcase.These substances will add as removed not in time
Fast machine oil goes bad and parts is made to be corroded or corrosion.Therefore, it is necessary to using crankcase ventilation system, engine is collaborated and is sent back to
Enter gas in-cylinder combustion to air inlet pipe and together with incoming mixture.
Due to organic oil particles of collaborating, machine oil can't burn completely, thus can increase exhaust pollution, while exacerbate machine oil
Consumption.
Invention content
The utility model by the function of engine air valve bonnet lid in order to reaching Oil-gas Separation, and to crankcase ventilation system
Collaborating in system carries out Oil-gas Separation processing, and spy proposes a kind of engine air valve bonnet lid of Oil-gas Separation.
The technical solution of the utility model is the engine air valve bonnet lid of a kind of Oil-gas Separation, including engine air thus
Valve bonnet lid is uniformly provided with multiple oil sealings among engine air valve bonnet lid, corresponding that multiple gas vents, hair are equipped in multiple oil sealing sides
One end of motivation air valve the cover is additionally provided with observation panel, it is characterised in that:Engine air valve bonnet lid inner wall has multiple vertical
Baffle；It is equipped with the oily bottom plate of gear under the baffle, keeps off oily bottom plate and is equipped with the corresponding oil sealing hole of the multiple oil sealings of engine air valve bonnet lid, gear
A cavity is formed between oily bottom plate and engine air valve bonnet lid inner wall, multiple vertical baffles form labyrinth type oil in cavity
Gas separation structure, while it is equipped with partition board on the oily bottom plate of gear.
Further improve is：Baffle is zigzag profile bar.
Further improve is：The oily bottom plate of gear is equipped with backflash, and has multiple oil return holes in the oily bottom plate of gear.
Further improve is：Partition board is porous plate.
Advantageous effect：
Engine air valve bonnet lid inner wall has multiple vertical baffles and air-fuel mixture air-flow direction in the utility model
In the same direction, when the engine operates, the athletic meeting of cylinder piston moves out fuel-air mixture stream, while in labyrinth type oil qi leel
From reflux movement in structure, the movement of air-fuel mixture air-flow direction is parallel to after encountering the partition board on the oily bottom plate of gear, due to oil droplet
Different with gas density, due to effect of inertia in flowing, larger oil droplet is adsorbed on engine air valve bonnet lid inner wall surface
Or on baffle, smaller oil droplet may then be carried over engine air valve bonnet lid with air-flow, inertia and shock using oil droplet
It realizes and detaches and collect.
The setting of backflash flows back to oil sump convenient for collecting the oil droplet captured and passing through oil return hole.
Partition board is increased, makes the path that dirty air is walked longer, pressure drop bigger.
Partition board for porous plate in order to preferably collect oil droplet and conducting and heat dissipation.
Baffle increases zigzag profile bar, increases the impact area of gas mixture and baffle.
The utility model improves the separative efficiency of oil mixture, increases according to the principle of engine air valve bonnet lid Oil-gas Separation
Oiling gas mixture makes the oil separated be easier to flow back to oil sump the shock number of baffle.
Description of the drawings
Fig. 1 is that the utility model looks up separation schematic diagram.
Fig. 2 is the vertical view separation schematic diagram of the utility model.
1 is engine air valve bonnet lid in figure, and 2 be multiple oil sealings, and 3 be multiple gas vents, and 4 be observation panel, and 5 be baffle, and 6 are
The oily bottom plate of gear, 7 be oil sealing hole, and 8 be partition board, and 9 be backflash, and 10 be oil return hole.
Specific embodiment
The utility model is as shown in Figure 1, 2.
The engine air valve bonnet lid of a kind of Oil-gas Separation, including engine air valve bonnet lid 1, among engine air valve bonnet lid 1
Multiple oil sealings 2 are uniformly provided with, corresponding to be equipped with multiple gas vents 3 in multiple 2 sides of oil sealing, one end of engine air valve bonnet lid 1 is also
Equipped with observation panel 4,1 inner wall of engine air valve bonnet lid has multiple vertical baffles 5；The oily bottom plate 6 of gear is had in baffle 5,
The oily bottom plate 6 of gear is equipped with more than 1 a 2 corresponding oil sealing hole 7 of oil sealing of engine air valve bonnet lid, keeps off oily bottom plate 6 and engine air valve bonnet
A cavity is formed between 1 inner wall of lid, multiple vertical baffles 5 form labyrinth type oil gas separation structure in cavity, while are keeping off
Partition board 8 is designed on oily bottom plate 6.
Baffle 5 is zigzag profile bar.
The oily bottom plate 6 of gear is equipped with backflash 9, and has multiple oil return holes 10 in the oily bottom plate 6 of gear.
Partition board 8 is porous plate.
