Fig. 3 shows to be provided with the cross sectional shape of the charge air flow path 10 of the orifice plate 140.With regard to the orifice plate 140 shown in Fig. 3
Speech, embodiment of the present utility model forms multiple plates in the left side or right side of orifice plate 140, but compares positioned at left side and right side most
The height of the plate on top, is able to know that different.
In the utility model so that the left side and right side of orifice plate 140 are highly formed as different, this is in order to which basis is started
The operating condition of machine changes air inlet flow behavior, and this is specifically described below.
As the utility model, changing air inlet flow section using orifice plate 140 and flap 120, and trigger rolling
In the case of flow phenomenon, especially when vehicle is to run at a low speed area and when the operating condition of engine is lower-speed state, with high speed shape
State is compared, and the air inflow flowed into combustion chamber is less, correspondingly, and fuel injection amount is also less situation, for reality
Now stablize and efficient burning, the initiation degree of preferably tumble flow phenomenon is uprised.
Now, the formation of flap 120 swing offset, and together with orifice plate 140 flow section of air inlet is subtracted
Less and keep, thus, occur the tumble flow phenomenon of combustion chamber, so as to lift the mixed performance between fuel and air inlet, and improve complete
Efficiency of combustion.
On the contrary, being the area etc. that runs at high speed when vehicle, when the operating condition of engine is lower-speed state, by than lower-speed state
The piston movement of fast combustion chamber and ensure the sinuous flow of combustion chamber.Therefore, compared to lower-speed state, what tumble flow phenomenon flowed must
The property wanted halves.
In addition, it is necessary to which the amount of the air inlet flowed into combustion chamber increases, in such situation under the fast state of engine
Under, if forming the swing offset of flap 120, the flow section of air inlet reduces, so that flow coefficient halves, it is unfavorable on the contrary
It is sufficient in air inflow, consequently, it is possible to causing engine efficiency to halve.In other words, the air inlet determined by flap 120
The flow section degree required according to the operating condition of engine changes.
Thus, the decision scope of the flow section of air inlet is various, then can more meticulously meet and be based on starting
The Air intake characteristics of the operating condition of machine, so that become favourable, wherein, the air inlet is determined by flap 120 and by orifice plate
140 keep and stabilize.
But, even if rotation flap 120 on the other, if to be also configured as position variable for the orifice plate 140, since it is desired that volume
Outer increase drive division 110 or design and the linkage structure of flap 120, so unfavorable in generation structure.
Thus, the utility model, which replaces, causes orifice plate 140 is set to variable, and the height for being arranged to left side and right side has
It is variant, so that air inlet flow section setting range is diversified.
For example, in the upper installing hole plate 140 of charge air flow path 10, the right side of the orifice plate 140 is highly set higher than left side height
Degree (equivalent to the situation that the right plate positioned at bottom is removed in the orifice plate 140 shown in Fig. 3), in the case, if hair
The operating condition of motivation is lower-speed state, then compared to fast state, triggers the degree requirement of the tumble flow phenomenon of combustion chamber
Higher, the flow section decrement of air inlet requires bigger.
In the case, flap 120 with cause its end be matched with the orifice plate 140 right side height it is (higher than left side
Position) mode rotate, tumble flow phenomenon trigger degree be set as maximum.
Now, the right side of orifice plate 140 is formed as the height corresponding with the rotation height of the flap 120 so that pass through
The flow section degree of described 120 reductions of flap is kept completely, and although the left side of orifice plate 140 is formed as keeping a little
Less than the height of the rotation height of the flap 120, but a certain degree of height is formed, effect is being triggered with tumble flow phenomenon
Aspect is abundant.
In addition, when the operating condition of the engine surmounts lower-speed state and is middling speed state, with the lower-speed state
Compared to, it is necessary to a little increase of the air inflow flowed into combustion chamber, compared to the lower-speed state of the engine, the rotation of flap 120
Highly it is decided to be a little low, is especially determined as highly corresponding with the left side of the orifice plate 140.
Now, air inlet is in the left side of orifice plate 140, is reduced and flowed with the highly corresponding height of the left side with the orifice plate 140
Dynamic sectional area simultaneously flows, and on the right side of orifice plate 140, although the flow section of reduction do not keep, but compared to flap
Before 120 swing offset is formed, the upper side collection to charge air flow path 10 occurs for the mean air entry flowing on the left side of orifice plate 140 and right side
In effect, compared with the lower-speed state of the engine, a little reduction of tumble flow effect, and air inflow (discharge coefficient) can be made a little
Perhaps increase.
In addition, the operating condition of the engine surmounts middling speed state and close to fast state on the basis of its rotary speed
When, flap 120 does not form the anglec of rotation, and is preferably located at the bottom of charge air flow path 10 in snugly manner, and the flowing of air inlet is cut
Area is identical with the sectional area of charge air flow path 10.Now, air inflow reaches maximum, and tumble flow phenomenon triggers effect to be minimum.
As described above, in the utility model, the left side of orifice plate 140 is different with the height that right side is formed, even if so as to set
Multiple air inlet flow sections can also be determined by putting an orifice plate 140, can be to the air inlet of the operating condition based on engine
Flow behavior carries out careful regulation, so as to effectively seek the lifting of engine efficiency while seeking to simplify the structure.
Fig. 1 shows the air inlet regulating device 100 of the vehicle of embodiment of the present utility model, and Fig. 2 shows of the present utility model

10 are divided by the orifice plate 140.
But, in the case where the flap 120 is located at than at the downstream of orifice plate 140, even if charge air flow path 10
Sectional area in a part of air inlet flowing cut off by the flap 120, because such cut-out is first to reach flap in air inlet
It can be realized after 120, thus it is interior as the interval that warp-wise is divided by orifice plate 140 before air inlet reaches flap 120
The state that portion is flowed into, thus in a part for the charge air flow path 10 for being divided and being cut off by flap 120 by the orifice plate 140
May occur the sinuous flows such as the vortex of air inlet.
As described above, setting the interval of abacus 140, the structure that air inlet is stagnated inlet air flow because of air inlet generation sinuous flow etc.
Moving may be hindered, consequently, it is possible to unfavorable.Thus, in embodiment of the present utility model, specially it is set to flap 120
Positioned at the upstream side of orifice plate 140, so as to carry out the regulation to the flow section of air inlet, thus improve air inlet flow section and adjust

Corresponding shape is set, so that charge air flow path 10 can be close to by being set to flap 120.
As mentioned earlier, sometimes according to vehicle travel speed or the operating condition of engine, in particular according to RPM shapes
State, it is necessary to which air inflow is increased as maximum situation compared with the initiation of tumble flow phenomenon.Especially, the rotating speed of engine is more high
Speed is more such.
Now, the situation of flap 120 is set on charge air flow path 10 turns into the key element for hindering air inlet flowing, can rise on the contrary
To the effect for being unfavorable for being lifted engine efficiency.Therefore, in embodiment of the present utility model, the shape of the flap 120 with
