Detailed description of the invention
From background technology, the Comprex supercharger of prior art is not having extra gas recirculation system
In the case of can not form waste gas recirculation.Inventor analyzes discovery, in prior art, it is contemplated that
Engine energy consumption efficiency and the problem of performance, the design of Comprex supercharger requires it is only will by exhaust gas pulse
Fresh air press-in internal combustion engine in Comprex supercharger.It is to say, existing Comprex supercharger
Rotor in unit exhaust gas pulse to the amount of internal combustion engine expellant gas be changeless, with realize just
The purpose that air in rotor is discharged.But, under some duty of internal combustion engine, more suitably
Portion is also pressed in internal combustion engine.Therefore, the present invention provides capacity adjustable pressure-wave supercharging
Device, when capacity is few, is only pressed into air to internal combustion engine, when capacity is many, in addition to air also
It is pressed into a part of waste gas to internal combustion engine.By above-mentioned means, it is achieved that according to different conditions, controllably enter
The purpose of row waste gas recirculation.
Illustrate how to regulate the capacity of Comprex supercharger below by specific embodiment.For making the present invention
Above-mentioned purpose, feature and advantage can become apparent from understandable, concrete to the present invention below in conjunction with the accompanying drawings
Embodiment is described in detail.It should be noted that provide the purpose of these accompanying drawings to contribute to understand this
Inventive embodiment, and should not be construed as the restriction improperly to the present invention.
The structural representation of existing Comprex supercharger 100, described pressure wave is shown with reference to Fig. 1, Fig. 1
Supercharger 100 includes rotor 110, the first dish 101, the second dish 103, internal combustion engine 150；Wherein, described turn
Son 110 includes multiple air flue 1102；Described first dish 101 connects free-air diffuser 104 and air outlet passage
102, described second dish 103 connects gas inlet road 106 and waste gas gas off-take 108.Described internal combustion engine 150
Exhaust gas pulse enter useless by described gas inlet road 106 in the air flue 1102 of described rotor 110
Gas.Described waste gas is compressed in described rotor 110 air sucked by described free-air diffuser 104.Quilt
The air of compression enters the cylinder of described internal combustion engine 150 by described air outlet passage 102.And it is trapped in institute
State the waste gas in rotor 110 and discharge described rotor 110 by described waste gas gas off-take 108 subsequently.
As it is shown in figure 1, the part that described first dish 101 connects described air outlet passage 102 has gas outlet
1011, the size of described gas outlet 1011, the quantity of described rotor air flue 1102, described rotor 110 turn
Speed, all can affect in an exhaust gas pulse to the capacity of internal combustion engine.Therefore, in prior art, this
A little parameters are all changeless, to realize only to the purpose of described internal combustion engine air-out.
Need explanation, the rotor 110 of above-mentioned pressure wave prelum only to described internal combustion engine 150 air-out,
Therefore be formed without waste gas recirculation, and described rotor 110 in each release for described internal combustion engine
The capacity of 150 is uncontrollable, and one of them release is that all described air flues 1102 are through described
Time used by gas outlet 1101.Through research, inventor finds no need for extra waste gas recirculation system
System, on the basis of above-mentioned Comprex supercharger enters, adds regulation parts, just can regulate described rotor
The discharge capacity discharging gas to internal combustion engine 150 of 110, thus realize waste gas recirculation.
Coordinate the structure of the Comprex supercharger of prior art, the adjustable pressure of capacity that the present invention provides
Pressure-wave supercharging device, farther includes to regulate parts, discharges the discharge of gas to internal combustion engine for regulating rotor
Amount.In an embodiment of the present invention, some regulation parts realize discharge capacity by the size adjusting QI KOU can
The function adjusted, some regulation parts realizes the adjustable function of discharge capacity by adjusting the rotating speed of rotor.
Fig. 2 illustrates the regulation parts of the adjustable Comprex supercharger of discharge capacity 200 of one embodiment of the invention

In certain embodiments, the shapes and sizes of described second gas outlet 2201 and described first gas outlet
(mark) is completely the same.So, as in figure 2 it is shown, described second gas outlet 2201 and described first
Gas outlet (mark) can be completely superposed, thus maximally utilises the first gas outlet so that it is can
The state that capacity is maximum can be operated in.As in figure 2 it is shown, under this duty, be completely superposed
Opening can make each air flue 2102 of rotor 210 maximum through gas outlet, i.e. evacuation time is the longest, from
And make the capacity of each described air flue 2102 reach the maximum in all working state.With existing skill
The gas outlet of art is compared, and the size of the first gas outlet in the embodiment of the present invention can arrange bigger, from
And realize the effect increasing capacity to discharge waste gas.Because the opening size of described first gas outlet is adjustable,
If having only to air-out in other duties, then can adjust the opening of described first gas outlet
Size is to existing size.
Fig. 3 illustrates that the regulation parts shown in Fig. 2 are in the structural representation under another kind of duty.
Under this duty, as it is shown on figure 3, give vent to anger in described second gas outlet 2201 and described first
Mouth (illustrating with label 2011 in figure 3) partially overlaps, and the opening size of intersection could be arranged to
Gas outlet consistent size with existing Comprex supercharger.Under this duty, described discharge capacity is adjustable
The Comprex supercharger of joint is consistent with the capacity of existing Comprex supercharger, in the most only air flows into
Combustion engine, thus do not form waste gas recirculation.
Need explanation, the gas of inflow internal combustion engine can also be regulated by controlling the opening size of intersection
The ratio of air and waste gas in body thus realize the change of quick control waste gas recirculation dilution rate.
In other embodiments, described Comprex supercharger also includes ring-like chiller, described ring-like cold

Described bent axle 170 rotates and drives described second pulley 1302, and described second pulley 1302 is by described transmission
Belt 1303 drives described first pulley 1301, described first pulley 1301 to drive described rotating shaft 1101 again,
So that described rotor 110 rotates.In prior art, described first pulley 1301 and described second is slided
The radius ratio of wheel 1302 is fixed, and the most described pulley system 130 is the pulley system of fixed proportion, at song
In the case of axle rotating speed is fixing, the rotating speed of rotor is also constant.
In some embodiments of the present invention, by the change to described pulley system 130 so that it is become defeated
Enter output than adjustable variable proportion pulley system.The input-output ratio of described variable proportion pulley system can
Adjust, such that it is able to the rotating speed of regulation rotor.In certain embodiments, described variable proportion pulley system
Parts and assembly relation are referred to existing pulley system 130 and arrange, and difference is described first pulley
1301 and described second pulley 1302 at least one replace with the adjustable pulley of radius, thus realize
The input-output ratio of this pulley system is adjustable.Wherein, the method for adjustable pulley radius can be technology in field
Any commonly employed control method known to personnel, is not defined this at this.
Air and waste gas in the gas of inflow internal combustion engine can also be regulated by changing the rotating speed of described rotor
Ratio thus realize the change of quick control waste gas recirculation dilution rate.
Although present disclosure is as above, but the present invention is not limited to this.Any those skilled in the art,
Without departing from the spirit and scope of the present invention, all can make various changes or modifications, therefore the guarantor of the present invention
The scope of protecting should be as the criterion with claim limited range.
