Crankcase assembly.
Background technology
As Engine Exhaust Emission increasingly requires strict, current crankcase ventilation system must all be enclosed circulation,
Gas blowby and machine oil gas will be recycled to engine aspirating system, into cylinder in burn, so for oil-gas separation efficiency
Will have high requirements, it is necessary to which oil droplet will be separated as much as possible, otherwise engine can produce burn oil phenomenon, influence
The unfailing performance of discharge performance and engine.
In the prior art, Oil-gas Separation is carried out mainly using two kinds of structures for crankcase, one kind is using a baffle plate
Formula gas oil separation structure, allows oil gas to pass through mazy passage in engine cylinder cover to reach the purpose of separation oil and gas, this knot
Structure oil-gas separation efficiency is not high.In the prior art labyrinth type oil gas separation structure shown in Fig. 1, oil gas mixture is left from passage
End enters, and because oil droplet is different with gas density, due to effect of inertia in flowing, larger oil droplet is adsorbed on separator
In interior surface or baffle plate, less oil droplet then may be carried over separator with air-flow.Using this labyrinth type oil qi leel
From passage, oil gas separation depend on cut-off number, then the resistance of whole ventilating system is increased too much, to reduction bent axle
The pressure of case is unfavorable, and then oil-gas separation efficiency is low very little.And the efficiency of current this labyrinth type oil gas separation structure is general only
Have 70% or so.
Another is that baffle-type gas oil separation structure adds a filter cartridge construction separator, although so separative efficiency
Height, but because filter core needs periodic replacement, the life-span is relatively low, and cost is high and complicated, and above-mentioned structure

In a second embodiment, crankcase Oil-gas Separation channel design is outside the first camshaft 2, in addition to the second cam
Axle 12.The first camshaft in a second embodiment is identical with first embodiment, is also quill shaft, is no longer repeated herein
Explanation.
Second camshaft 12 is substantially similar to the first camshaft 2, but its inlet end and outlet side and the phase of the first camshaft 2
Instead.Specifically, the second camshaft 12 is hollow camshaft, and having at its first end (right-hand member in Fig. 3) place is used to input oil
Second oil gas entrance 14 of gas mixture；Multiple second sidewall through holes 15 are carried on the side wall of the second camshaft 12, for arranging
Go out the fluid isolated during the rotation of the second camshaft 12；Have second at the second end (left end in Fig. 3) place of the second camshaft
Oil gas vent 16, for discharging the oil gas mixture after being separated by secondary oil gas.Second oil gas entrance 14, second sidewall are led to
Shape, size, quantity and the arrangement mode of the oil gas vent 16 of hole 15 and second can be arranged as required to.
In the embodiment shown in fig. 3, the second oil gas entrance 14 and the second oil gas vent 16 are radial passage, and it extends
Central axis of the direction perpendicular to the second camshaft 12.Advantageously, as shown in figure 3, the second oil gas entrance 14 and the second oil gas
Outlet 16 is circular hole, moreover, the quantity of the second oil gas entrance 14 and the second oil gas vent 16 could be arranged to 4 (referring to figure
4) is that is, the second oil gas entrance 14 and the second oil gas vent 16 each include four uniform through holes in the circumferential.
For the ease of the sealing of oil gas mixture, sealing shroud is also equipped with the two ends of the second camshaft 12.It can manage
Solution be, it would however also be possible to employ other sealing structures seal come the two ends to the first hollow camshaft 2.
For the ease of the input and output of oil gas mixture, with the second oil gas entrance 14 and second on crankcase bodies 1
Oil gas vent 16 is respectively arranged with the 3rd circular trough 17 and the 4th circular trough 18 at corresponding position.It will need to carry out secondary oil gas
The oil gas mixture (processing for passing through the first camshaft) of separation imports the 3rd circular trough 17 by interface channel 10
It is interior, then entered by the second oil gas entrance 14 inside the second camshaft 12, carry out Oil-gas Separation.Finally, by Oil-gas Separation
Gas mixture be directed to the 4th circular trough 18 and be exported the second camshaft 12.Similar with the first camshaft, second is convex
The inwall of wheel shaft 12 uses rough surface.In order to drive oil gas mixture to be rotated with the first camshaft, and carry out centrifugation oil gas
Separation.
In order to improve oil gas separation, the direction of rotation of the second camshaft 12 is set to the rotation with the first camshaft 2
In the opposite direction.It is right because big reverse occurs for gaseous mixture rotation direction when gaseous mixture enters the second camshaft from the first camshaft
Punching effect is the most notable, thus the Oil-gas Separation of maximal efficiency will occur in this position.The inverse rotation opposite direction collisions in this stage
Separation, belongs to the decay of central collision momentum.The gaseous mixture flowed out from the first camshaft with speed V1=r θ, front knocks rotating speed for V2=
R ω the second camshaft, moment is V=r θ+r ω with respect to impact velocity, and now the momentum of oil droplet is mr (θ+ω) extremely short
Time is attenuated, and drop pressure is attached on wall equivalent to great power, is formed oil film and then to be formed oil return by getting rid of.
In the embodiment shown in fig. 3, the diameter parallel of the second camshaft 12 is in the axis of the first camshaft 2.It is appreciated that
, the axis of the second camshaft 12 can also be with the axis of the first camshaft 2 at an angle, or is mutually perpendicular to, these changes
Example is all within protection scope of the present invention.
Referring to Fig. 3, the second end of the first end of the second camshaft 12 and the first camshaft 2 is located at the of crankcase bodies 1
Side (right side) place.The first end of second end of the second camshaft 12 and the first camshaft 2 be located at crankcase bodies 1 with it is described
First side relative opposite side (left side) place.
The first oil gas vent 6 at the second end of the first camshaft 2 is communicated to positioned at second by interface channel 10
The second oil gas entrance 14 at the first end of camshaft 12.In the illustrated embodiment, interface channel 10 is straight channel, and it extends
Direction is with the axle center of the first camshaft 2 and the axial connecting line in the axle center of the second camshaft 12 at an angle (referring to Fig. 4).
The axis of second circular trough 8 is overlapped with the axis of the first camshaft 2, and the first oil gas vent 6 of the first camshaft 2
Connected with the second circular trough 8.The axis of 3rd circular trough 17 is overlapped with the axis of the second camshaft 12, and the second camshaft 12
Second oil gas entrance is connected with the 3rd circular trough 17.Interface channel 10 connects the circular trough 17 of the second circular trough 8 and the 3rd.Will
Above-mentioned crankcase Oil-gas Separation channel design is used for crankcase assembly so that crankcase (can be needed using original camshaft
Structure of modification is carried out to camshaft, but installation dimension does not have and dramatically increased) Oil-gas Separation is carried out, so that crankcase is total
Into it is simple in construction, compact.It is last it is to be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than
It is limited.Although the present invention is described in detail with reference to the foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Carry out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention skill
The spirit and scope of art scheme.
