Description
Technical field
The present invention relates to a kind of gas valve, particularly a kind of exhaust gas valve of turbosupercharged engine.
Background technique
The supercharged engine of existing automobile, usually adopt bi-turbo or turbosupercharger to add mechanical supercharger to dissolve its turbo lag, ubiquity supercharged engine structure is numerous and diverse, the shortcoming of cost height enterprise; Although what have directly adopts mechanical supercharger, but still the power of loss supercharged engine, oil consumption is higher.
Summary of the invention
The technical problem to be solved in the present invention is, supercharged engine structure for existing automobile is numerous and diverse, cost height enterprise, the shortcoming that oil consumption is higher, a kind of exhaust gas valve is provided to configure turbosupercharged engine to dissolve its turbo lag, thus it is simple to realize a kind of structure, with low cost, the single turbine supercharged engine that oil consumption is lower.
Technological scheme of the present invention is, a kind of exhaust gas valve, comprises valve, cylinder barrel, and the air valve seat ring that described cylinder barrel is arranged, valve guide bushing and spring are connected with valve; Described valve is nail-shaped pneumatic door, and its head is connected with air valve seat ring, spring, and bar portion is connected with valve guide bushing; The top of described cylinder barrel is connected with exhaust passage, and bottom is connected with gas exhaust manifold.
The invention has the beneficial effects as follows, contribute to the turbo lag dissolving turbosupercharged engine, thus it is simple to realize a kind of structure, with low cost, the single turbine supercharged engine that oil consumption is lower.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention;
Fig. 2 is the worm's eye view of embodiment of the present invention cylinder barrel;
Fig. 3 is the plan view of embodiment of the present invention cylinder barrel.
Embodiment
Below in conjunction with accompanying drawing and implementation column, further describe technological scheme of the present invention.
Technological scheme of the present invention is, a kind of exhaust gas valve comprises valve 1, cylinder barrel 2, and the air valve seat ring 4 that described cylinder barrel 2 is arranged, valve guide bushing 6 and spring 7 are connected with valve 1; Described valve 1 is nail-shaped pneumatic door, and its head is connected with air valve seat ring 4, spring 7, and bar portion is connected with valve guide bushing 6; The top of described cylinder barrel 2 is connected with exhaust passage, and bottom is connected with gas exhaust manifold.
Embodiment
In the embodiments of the invention shown in Fig. 1, Fig. 2, Fig. 3, cylinder barrel 2 adopts cast iron or alloy material to make internal diameter to mate with the exhaust passage of single turbine supercharged engine, wall height about 2-5cm, and wall thickness is about the funnel shape cylinder barrel of 0.5-1.5cm; Symmetrical four splicing holes, road 3 on the cross-section of cylinder barrel 2, to configure; Inlaying at the inwall on cylinder barrel 2 top metallic material that one employing have a some strength, to make specification suitable, and inner side is processed with the annular air valve seat ring 4 on a circle cone angle inclined-plane; To distribute four road fanlights 5 at cylinder barrel 2 bottom symmetrical, to be vented; Center bottom cylinder barrel 2 is processed with the suitable circular hole of one internal diameter, inlay metallic material that one employing have a some strength in this circular hole to make bar portion diameter and mate with its internal diameter, head diameter is about less than following spring seat internal diameter, internal diameter and the nail-shaped valve guide bushing 6 be of convenient length; Bottom cylinder barrel 2, arrange one specification suitable, two ends respectively have boss shape spring seat and resistant to elevated temperatures spiral spring 7.The metallic material that valve 1 employing of the present invention has some strength is made head diameter and is about greater than air valve seat ring 4 internal diameter, and bar portion diameter is about less than valve guide bushing 6 internal diameter, the nail-shaped pneumatic door be of convenient length; The cone angle inclined-plane that a circle mates with air valve seat ring 4 is processed with, to guarantee that valve 1 and air valve seat ring 4 fit tightly in the upside of valve 1 head; The diameter matches of one diameter and valve guide bushing 6 head is processed with, highly suitable boss below valve 1 head.In this example, valve guide bushing 6 can guide valve 1 to do correct axial stretching motion; The boss of valve guide bushing 6 head and valve 1 head touches, and effectively can limit the open degree of valve 1.Conveniently assemble, first valve guide bushing 6 should be fixed on bottom cylinder barrel 2 in this example, and spring 7 is arranged on bottom cylinder barrel 2, then by valve 1 bar portion through spring 7 and valve guide bushing 6, then air valve seat ring 4 is fixed on cylinder barrel 2 top.
As everyone knows, four cylinder supercharged engine light or compression ignite order for first cylinder-the third cylinder-Ding cylinder-second cylinder.The gas exhaust manifold of four common cylinder single turbine supercharged engine is by four exhaust passage parallel connections, makes waste gas rush at turbosupercharger along scroll; Its drawback is, if during the third cylinder working, the intake valve of cylinder in a flash and exhaust valve is had all to be in opening state, first cylinder has completed acting and has been exhausted this moment, because the exhaust passage of first cylinder and the third cylinder communicates with each other by means of gas exhaust manifold, this alters into the third cylinder with regard to causing the waste gas of first cylinder, the air inflow of the third cylinder is reduced, causes the power of its expansion stroke to decrease; In like manner, other cylinders move in circles.In order to evade above-mentioned drawback, in this example, four the present invention are configured in respectively four of four cylinder single turbine supercharged engine between exhaust passage and gas exhaust manifold, when the waste gas that certain cylinder produces arrives at of the present invention along exhaust passage, valve 1 is washed open by the tension force that its heat wave can overcome spring 7 easily, and rush at turbosupercharger through transom window 5 along gas exhaust manifold and scroll, otherwise then valve 1 is closed rapidly by spring 7 automatically, the waste gas produced to stop other cylinders is altered into this cylinder through gas exhaust manifold, therefore, be exhausted when first cylinder completes acting, third cylinder enters aspirating stroke, do not communicate each other because first cylinder is all configured with the present invention with the exhaust passage of the third cylinder, so the exhaust of first cylinder can not have influence on the air inlet effect of the third cylinder, the air inlet of two cylinders like this, exhaust does not interfere with each other, impel the air inflow that each cylinder reaches maximum, air displacement, to promote the efficiency of this supercharged engine further.Even if compared to the supercharged engine that existing automobile adopts bi-turbo, turbosupercharger adds mechanical supercharger or mechanical supercharger, not only overall structure is relatively simple to be configured with single turbine supercharged engine of the present invention, manufacture cost is corresponding cheap, and pulse pressure-charging effect is quite powerful, this is in the low turn of turbo lag accelerated by dissolving single turbine supercharged engine as much as possible, so that its Peak torque embodies more early, fuel economy is better.
The invention has the beneficial effects as follows, contribute to the turbo lag dissolving turbosupercharged engine, thus it is simple to realize a kind of structure, with low cost, the single turbine supercharged engine that oil consumption is lower; It is mainly used in the single turbine supercharged engine configuring various automobile.
