Description
Technical field
A kind of air flue is the utility model is related to, particularly a kind of air passage of internal combustion engine.
Background technology
Internal combustion engine mainly includes air inlet system and exhaust system, fuel feed system and combustion chamber, and the core of air inlet system and exhaust system zero
One of part is exactly air flue, and it largely affects the fresh charge for being often recycled into cylinder and the motion of cylinder interior air-flow is strong
Degree.
The air flue of prior art is generally configured to the air intake duct of two difference, still, due to two air flues to have it is certain
Clearance distance and wall thickness, cause that air inlet sectional area is smaller, and air inlet is insufficient, it is impossible to and mist of oil mixes well.
Utility model content
The purpose of this utility model is to provide a kind of air passage of internal combustion engine, to solve technical problem of the prior art, its energy
Enough ensure larger air inflow and larger intake swirl, form larger swirl ratio, the gas of abundance is entered combustion chamber.
The utility model provides a kind of air passage of internal combustion engine, including spiral inlet duct, and the spiral inlet duct is close to internal combustion
One end of machine is provided with vortex air intake road and tangential inlet duct Liang Ge branches；
The vortex air intake road and the tangential inlet duct are arranged side by side, and the vortex air intake road and the tangential admission
Road is connected with the spiral inlet duct arc transition respectively.
Foregoing air passage of internal combustion engine, it is preferable that the one end of the spiral inlet duct away from internal combustion engine is open-like shape.
Foregoing air passage of internal combustion engine, it is preferable that the vortex air intake road and the tangential inlet duct and the spirally inlet air
Road has the angle more than 90 °, and corner's rounding off.
Foregoing air passage of internal combustion engine, it is preferable that the spiral inlet duct, the vortex air intake road and the tangential inlet duct
Inner surface it is smooth.
Foregoing air passage of internal combustion engine, it is preferable that the spiral inlet duct, the vortex air intake road and the tangential inlet duct
On be respectively equipped with multiple escape groove.
Compared with prior art, the utility model is by designing a spiral inlet duct, and in the end of spiral inlet duct
Vortex air intake road and tangential inlet duct Liang Ge branches are set so that the air passage of internal combustion engine not only has larger intake swirl and entered
Tolerance, also with larger swirl ratio, the gas of abundance is set to enter combustion chamber；And two air flues are combined into one, air inlet sectional area
Greatly, air inflow is bigger than two air flues of prior art, is also easier to arrange in arrangement.

Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng
The embodiment for examining accompanying drawing description is exemplary, is only used for explaining the utility model, and can not be construed to of the present utility model
Limitation.
Embodiment of the present utility model：As Figure 1-4, a kind of air passage of internal combustion engine, it is mainly used for the air inlet of internal combustion engine
System, including spiral inlet duct 1, the spiral inlet duct 1 are provided with vortex air intake road 2 and tangential admission close to one end of internal combustion engine
The Liang Ge branches of road 3；The vortex air intake road 2 and the tangential inlet duct 3 are arranged side by side, and the vortex air intake road 2 and described
Tangential inlet duct 3 is connected with the arc transition of spiral inlet duct 1 respectively.The utility model is by designing a spiral inlet duct
1, and in the end set vortex air intake road 2 of spiral inlet duct 1 and the Liang Ge branches of tangential inlet duct 3 so that the air passage of internal combustion engine
Not only there is larger intake swirl and air inflow, also with larger swirl ratio, the gas of abundance is entered combustion chamber.Its
In, vortex air intake road 2 can form larger intake swirl；The big air inflow of the principal security of tangential inlet duct 3；Spiral inlet duct
1 mainly provides larger swirl ratio.And two air flues are combined into one, air inlet sectional area is big, and than two air flues of air inflow are bigger, cloth
Put and be also easier to arrange.
Specifically, in order to be open-like shape with larger air inflow, the described one end of spiral inlet duct 1 away from internal combustion engine,
I.e. the inlet end of spiral inlet duct 1 is open-like shape, is advantageous to the entrance of gas.
In a kind of specifically embodiment, in order to avoid the air flue abrupt change of cross section, the vortex air intake road 2 and described tangential
Air intake duct 3 has the angle more than 90 °, and corner's rounding off with the spiral inlet duct 1.Because inside internal-combustion engine system
Space is limited, and the inlet and outlet of its air intake duct not point-blank, in order to avoid the air flue abrupt change of cross section, influences air inlet mostly
Vortex and swirl ratio, are designed as obtuse angle, and rounding off around the corner.More specifically, the spiral inlet duct 1, the vortex
The inner surface of air intake duct 2 and the tangential inlet duct 3 is smooth.Can further smaller extraneous factor to intake swirl and vortex
The influence of ratio.
In another specifically embodiment, in order to avoid interference, the spiral inlet duct 1, the vortex air intake road 2
With multiple escape groove 4 are respectively equipped with the tangential inlet duct 3.Because interior space is limited, the parts of internal-combustion engine system are again
More, air intake duct, which cheats you, to produce interference with other parts, so in spiral inlet duct 1, vortex air intake road 2 and tangential admission
Multiple escape groove 4 are respectively equipped with road 3, to avoid the interference with other parts.
Construction, feature and action effect of the present utility model is described in detail according to the embodiment shown in schema above, with
Upper described is only preferred embodiment of the present utility model, but the utility model is to limit practical range shown in drawing, it is every according to
According to the made change of conception of the present utility model, or the equivalent embodiment of equivalent variations is revised as, still without departing from specification and figure
, all should be in the scope of protection of the utility model when showing covered spirit.
