Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is made further
Describe in detail.Following example are used for illustrating this utility model, but it is new to be not limited to this practicality
The scope of type.
Described Inlet Swirl produces air flue and specifically refers to produce the air flue of Inlet Swirl, produces air inlet
The particular location of the air flue of eddy flow is relevant with inlet manifold space structure, the air inlet discrimination of different structure
Pipe, the position of the air flue producing Inlet Swirl can be different.But, for arbitrary structures
Inlet manifold, in the case of structure determines, those skilled in the art all can be by three-dimensional CFD
Simulation calculation software analog simulation determines the air flue producing Inlet Swirl in inlet manifold.Therefore,
For the inlet manifold of arbitrary structures, it is accurately to determine that its Inlet Swirl produces air flue
's.
As shown in Figures 1 and 2, show schematically show certain inlet manifold without flow deflector
Structure, it includes the air flue 2 that pressure stabilizing cavity 1 and one end connect, air flue 2 with pressure stabilizing cavity 1
The other end connect with the cylinder cap of electromotor (not shown), pressure stabilizing cavity 1 is provided with and solar term
The air inlet 3 that door (not shown) connects；Due to this inlet manifold concrete structure it has been determined that
By software CFD analog simulation, Inlet Swirl can be produced in the first air flue 2a, the
One air flue 2a is Inlet Swirl and produces air flue, and the second air flue 2b air inlet ratio is smoothly, the
Two air flue 2b are non-Inlet Swirl and produce air flue；The Inlet Swirl produced in first air flue 2a,
On the one hand can greatly increase the air inlet crushing of the first air flue 2a, limiting the first air flue 2a has
Effect air inflow, on the other hand, the air inlet crushing of air inlet the second air flue 2b smoothly is less, because of
This, the existence of Inlet Swirl can make the first air flue 2a crushing than the second air flue 2b high, starts
The intake uniformity of each cylinder of machine is poor.
As it is shown on figure 3, in order to eliminate the Inlet Swirl in the first air flue 2a, at the first air flue
Being provided with more than one flow deflector 4 on the inwall of 2a, this flow deflector 4 is at the first air flue 2a
Prolong to the one end away from pressure stabilizing cavity 1 along airintake direction by the one end near pressure stabilizing cavity 1 on inwall
Stretch, the Inlet Swirl that flow deflector 4 produces in can being effectively limited in the first air flue 2a, thus
The first air flue 2a that flows through that can guide air-flow more swimmingly enters the combustor of electromotor,
Reduce the air inlet crushing of the first air flue 2a, reduce generation Inlet Swirl to a certain extent
The first air flue 2a and air inlet the second air flue 2b smoothly between air inlet crushing difference.
Although flow deflector 4 can limit the Inlet Swirl in the first air flue 2a, reduce the first gas
The air inlet crushing of road 2a, but it is affected by the impact of 4 body structures of flow deflector, also can be first
A certain degree of air inlet crushing is there is, therefore, at the first air flue 2a and the second gas in air flue 2a
Also can there is certain air inlet crushing difference between road 2b, thus also can affect each cylinder of electromotor
The uniformity of air inlet.
As shown in Figure 4, after reducing further flow deflector be set in the first air flue 2a,
The air inlet crushing that first air flue 2a and the second air flue 2b exist is poor, in each air inlet smooth and easy the
More than one flow deflector 4 it is provided with equally in two air flue 2b (non-Inlet Swirl generation air flue),
Suitably to improve the air inlet crushing in this second air flue 2b, i.e. every in this inlet manifold
More than one flow deflector 4 it is respectively provided with, to balance the first air flue 2a and the second gas in individual air flue
The air inlet crushing of road 2b, reduces the air inlet crushing between the first air flue 2a and the second air flue 2b
Difference, the effective admission amount making each air flue is more uniform, to ensure each cylinder intake of electromotor
Uniformity.
As it is shown in figure 5, the quantity of the flow deflector 4 in single air flue is set to two or three,
It is preferably, two flow deflectors 4 is set in single air flue, it is possible to obtain preferably water conservancy diversion effect,
And along with the increase of flow deflector 4 quantity, then can increase the air inlet crushing in air flue, thus can drop
The effective admission amount of low electromotor, therefore, it is not recommended that arrange too much flow deflector 4；Each
Two ends of flow deflector 4 are respectively provided with arcuation diversion division 40, and diversion division 40 is preferably arc-shaped,
The diversion division 40 of arcuation can reduce the air inlet crushing of air flue, improves the effective admission amount of air flue.
As shown in Figure 6, the first air flue 2a (Inlet Swirl generation air flue) include a diapire 21,
Be connected to described diapire 21 two ends two sidewalls 22 and relative with described diapire and
Two ends are respectively connecting to the roof 23 of said two sidewall, and described roof 23 is to diapire 21 side
To concave shape camber inner fovea part 24, described diapire 21, both sides sidewall 22, roof 23
Junction is all by circular arc 25 transition；On the diapire 21 of each the first air flue 2a fixed
Having flow deflector 4, flow deflector 4 is substantially parallel with two sidewalls 22, preferably each first
The distance s arranged in air flue 2a between two flow deflectors 4 and this two flow deflectors 4 is two
/ 3rd of the spacing of sidewall 22, the height h of flow deflector 4 is less than diapire 21 and roof
/ 4th of the minimum spacing of 23, it is preferable that the height h of flow deflector 4 be diapire 21 with
/ 6th of the minimum spacing of roof 23；So arrange and can limit the first gas to greatest extent
Inlet Swirl in road 2a (Inlet Swirl generation air flue), fully to reduce in the first air flue 2a
Air inlet crushing.
In conjunction with shown in Fig. 4 to Fig. 6, for a preferred embodiment of the present utility model, air inlet
Mouth 3 is arranged on the middle part of pressure stabilizing cavity 1, is provided with four air flues, these four gas on pressure stabilizing cavity 1
Road is arranged in order along the length direction of pressure stabilizing cavity 1, the most solid on the diapire 21 of these four air flues
Being provided with two flow deflectors 4, the height h of flow deflector 4 is 5mm.
When being not provided with flow deflector 4 in air flue, through three-dimensional CFD software simulation analysis,
Can produce in hithermost two the first air flue 2a that is two, triplex air flues with air inlet 3
Raw Inlet Swirl, and at two second air flue 2b that is, four cylinder air flues at pressure stabilizing cavity 1 two ends
Air inlet ratio smoothly, through measuring and calculating, now the entering of two, triplex air flue and one, four cylinder air flues
Air pressure damages difference ± 10%；And respectively arrange in two, triplex air flue and one, four cylinder air flues
After two flow deflectors 4, being calculated analytically, total air flue mean air entry crushing reduces 10%,
And two, triplex air flue and one, four cylinder air flue air inlet crushing differences by original ± 10% drop to
Final ± 3%, effect of optimization is fairly obvious.
The invention also discloses starting of a kind of inlet manifold comprised in above-described embodiment
Machine, this electromotor can be petrol engine, it is also possible to be Diesel engine.
The above is only preferred implementation of the present utility model, it is noted that for this skill
For the those of ordinary skill in art field, in the premise without departing from this utility model know-why
Under, it is also possible to making some improvement and replacement, these improve and replace and also should be regarded as this practicality newly
The protection domain of type.
