Description
Technical field
The present invention relates to diesel engine arts, more particularly to a kind of V-type diesel air inlet tube.
Background technology
For diesel engine, air is simply distributed and is transitioned on air inlet pipe of diesel engine by air inlet tube after charge air cooler cooling,
In order to reduce in gas flow resistance, raising air inlet ability, air inlet tube, gas flow inwall should be smooth, and length should be as far as possible
It is short.The air inlet tube of traditional straight-row diesel engine is exactly one section of adapter, and the air inlet tube of traditional V-type diesel is also two sections mutual
Separated adapter.Or adapter separated from each other is simply integrated into an air inlet tube, but inner chamber is also divided into independence
Levels adapter.
Existing V-type diesel air inlet tube has the disadvantages that：1st, air inlet tube special purpose parts separated from each other is more, takes
Space is big, and assembling is complicated difficult, does not reach lightweight requirements；2nd, complete machine arrangement is complicated, and not compact enough, outward appearance is in disorder, unsightly；
3rd, independent air inlet tube circulation area separated from each other diminishes, and causes flow resistance to increase, air inlet scarce capacity；4th, air inlet is cut
Flow, rob gas phenomenon, each cylinder air inlet is uneven.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
When the prior art for being considered as recognizing or implying the information structure in any form well known to persons skilled in the art.
The content of the invention
It is an object of the invention to provide a kind of V-type diesel air inlet tube, air inlet uniformity, compact conformation.
To achieve the above object, the invention provides a kind of V-type diesel air inlet tube, including：Tube body, sets inside it
There is pressure stabilizing cavity；Two outlet interfaces, it is arranged on the low side both sides of tube body, the internal diameter of two outlet interfaces it is consistent and respectively with
Pressure stabilizing cavity is connected, and the centre distance that two outlets are interfaced to pressure stabilizing cavity is equal：Intake interface, its internal diameter is more than two outlet interfaces
Internal diameter, the intake interface is arranged on the upper end of tube body, intake interface and pressure stabilizing cavity insertion.
Preferably, intake interface is arranged on the tube body of two outlet interface middle upper parts.
Preferably, intake interface and two outlet interfaces are integrally formed with tube body and then form trifid structure.
Compared with prior art, the present invention has the advantages that：By designed on a tube body outlet interface,
Outlet interface, intake interface and a pressure stabilizing cavity, belong to integrated design, reduce amount of parts, simple in construction, convenient
Arrangement, it is convenient for assembly, cost, reduction assembly difficulty and intensity are reduced, compact conformation is elegant in appearance.And pass through two outlets
Interface is symmetrically arranged on the low side both sides of tube body, and the internal diameter of two outlet interfaces is consistent and is connected respectively with pressure stabilizing cavity, two
The centre distance that individual outlet is interfaced to pressure stabilizing cavity is equal, can solve V-type diesel air inlet and dam, robs gas phenomenon, it is ensured that each cylinder
Intake uniformity so that each cylinder of diesel engine fully burns, improves emission level.
Brief description of the drawings
Fig. 1 is the structural representation according to V-type diesel air inlet tube of the present invention.
Embodiment
Below in conjunction with the accompanying drawings, the embodiment to the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in Fig. 1 to figure, according to a kind of V-type diesel air inlet tube of the specific embodiment of the invention, including pipe sheet
Body 3, two outlet interfaces (2,4) and intake interface 1, the wherein inside of tube body 3 are provided with pressure stabilizing cavity 5, two outlet interfaces (2,4)
The low side both sides of tube body 3 are arranged on, the internal diameter of two outlet interfaces (2,4) is consistent and is connected respectively with pressure stabilizing cavity 5, and two go out
Gas interface (2,4) is equal to the centre distance of pressure stabilizing cavity 5, and the internal diameter of intake interface 1 is more than the interior of two outlet interfaces (2,4)
Footpath, the intake interface 1 is arranged on the upper end of tube body 3, intake interface 1 and the insertion of pressure stabilizing cavity 5.
As a kind of preferred embodiment, intake interface 1 is arranged on the tube body 3 of two outlet interface (2,4) middle upper parts
On.
As a kind of preferred embodiment, intake interface 1 and two outlet interfaces (2,4) be integrally formed with tube body 3 and then
Form trifid structure.
In such scheme, V-type diesel air inlet tube is securely fitted on V-type diesel by tube body 3, tube body 3
Outlet interface 2, outlet interface 4, intake interface 1 and a pressure stabilizing cavity 5 are provided with, the internal diameter of outlet interface 2 and outlet interface 4 is
Identical, the internal diameter of intake interface 1 is greater than the internal diameter of outlet interface 2 and outlet interface 4, and pressure stabilizing cavity 5 is to penetrate into outlet to connect
Mouthfuls 2, outlet interface 4, on intake interface 1, pressure stabilizing cavity 5 can guarantee that the stabilization of admission pressure, and then reduce charge pulsation.
Air through charge air cooler cooling it is laggard arrive intake interface 1, flow through pressure stabilizing cavity 5, by voltage stabilizing be diverted to outlet interface 2 with
On outlet interface 4, air is entered on air inlet pipe of diesel engine by outlet interface 2 and outlet interface 4.Because pressure stabilizing cavity 5 is to pass through
Pass-out gas interface 2 and outlet interface 4, and two interface internal diameters are the same, institute the same to the air inlet pipe on both sides distance from pressure stabilizing cavity 5
With in the absence of damming, robbing gas phenomenon, so as to can guarantee that each cylinder intake uniformity so that each cylinder of diesel engine can fully burn, and carry
Maximum discharge level.
To sum up, the V-type diesel air inlet tube of the present embodiment, by designing outlet interface 2 on a tube body 3, going out
Gas interface 4, intake interface 1 and a pressure stabilizing cavity 5, belong to integrated design, reduce amount of parts, simple in construction, side
Just arrange, it is convenient for assembly, cost, reduction assembly difficulty and intensity are reduced, compact conformation is elegant in appearance.And gone out by two
Gas interface (2,4) is symmetrically arranged on the low side both sides of tube body 3, the internal diameter of two outlet interfaces (2,4) it is consistent and respectively with
Pressure stabilizing cavity 5 is connected, and two outlet interfaces (2,4) are equal to the centre distance of pressure stabilizing cavity 5, can be solved V-type diesel air inlet and be cut
Flow, rob gas phenomenon, it is ensured that each cylinder intake uniformity so that each cylinder of diesel engine fully burns, improve emission level.
It is foregoing to the present invention specific illustrative embodiment description be in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explaining that the certain principles and its reality of the present invention should
