Embodiment
In the accompanying drawings, use same or similar label to represent same or similar element or there is element that is identical or similar functions.Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Suction port 1, intake duct 2, pressure regulator valve 4, pressurized machine inlet end interface 5 intake manifold interface 6 and spiral oil gas separation assembly 7 have been shown in Fig. 2.Spiral oil gas separation assembly 7 comprises housing 71, and housing 71 is provided with separation assembly suction port 72 and spiral gas guide groove 73.
As shown in Figure 2, crankcase fuel-air mixture enters suction port 1, is entered in spiral oil gas separation assembly 7 by intake duct 2.Gas after separation enters pressurized machine inlet end interface 5 or the intake manifold interface 6 of engine aspirating system under the control of pressure regulator valve 4.
When engine idle or low load operation, intake manifold is negative pressure, and the gas after separation enters in-cylinder combustion through intake manifold interface 6; During full engine load running, intake manifold is malleation, and pressurized machine inlet end is negative pressure, and the gas after being now separated enters in-cylinder combustion through pressurized machine inlet end interface 5.
See Fig. 3, the housing 71 of spiral oil gas separation assembly 7 is provided with separation assembly suction port 72 and spiral gas guide groove 73.Spiral gas guide groove 73 is arranged on the inwall of described housing 71, to spin motion for guiding the gas mixture entered from separation assembly suction port 72.
Preferably, described housing 71 limits a bucket-shaped space wide at the top and narrow at the bottom.
Preferably, described spiral gas guide groove 73 extends to the bottom in described bucket-shaped space from the top in described bucket-shaped space.
Preferably, described spiral gas guide groove 73 is limited by the inwall of described housing and the helical blade be fixed on described inwall.In a preferred embodiment, helical blade is bonding or be threaded on the inwall of housing 71.Helical blade is advantageously combined by the blades that multi-disc is identical, and blades is with injection molding manner manufacture.
Preferably, the degree of depth of described spiral gas guide groove 73 is between 1-5 millimeter.
Preferably, the width of described spiral gas guide groove 73 is between 3-15 millimeter.
Preferably, the pitch of described spiral gas guide groove 73 is between 5-20 millimeter.
Preferably, described separation assembly suction port 72 is connected with described spiral gas guide groove 73 is tangent.
Preferably, described separation assembly suction port 72 is positioned at the top place of described housing.
The utility model also provides a kind of engine assembly, and wherein, described engine assembly comprises spiral type oil gas separating device as above.
Housing due to the spiral oil gas separation assembly of spiral type oil gas separating device of the present utility model is provided with spiral gas guide groove, thus can lead to mixed gas, it is made to move along spiral gas guide groove, can gas be effectively avoided mutually to disturb, gas can be made again to obtain larger centrifugal force, thus obtain better separating effect.
Compared to traditional cyclone type oil air separation, spiral oil gas separation assembly can better carry out Oil-gas Separation work.Mixed gas is in the tangent housing 71 entering spiral oil gas separation assembly 7 of separation assembly suction port 72, and under the effect of contraction of spiral gas guide groove 73, mixed gas carries out circular movement, by Oil-gas Separation under centrifugal action along spiral gas guide groove 73.Oil droplet after separation enters oil sump from housing 71 lower end, and gas enters combustion system from housing 71 upper end.
Spiral type oil gas separating device of the present utility model has following advantage.
The first, engine oil consumption can be reduced.Except normal lubrication system consumption, there is a large amount of fuel-air mixture in engine oil consumption, if do not say, this part mixed gas carries out being separated direct burning, can cause the too fast consumption of machine oil in crankcase.So spiral type oil gas separating device can reduce Oil Consumption of Engine better.
The second, existing cyclone type oil-gas separator separating effect is not good, and during time of engine low speed, the gas after separation directly enters intake manifold, because separation rate is not high, so can there is fuel oil at recent manifold tube wall place, affects engine charging efficiency; When high engine speeds operates, can there is fuel oil through pressurized machine in the too much gas of oil-containing, affect booster performance equally on booster turbine blade and inwall.Spiral type oil gas separating device can effectively avoid intake manifold tube wall to have the phenomenon of oil; Effectively can keep the clean of pressurized machine internal work environment, increase pressurized machine operating life.
