Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Fig. 1 is a schematic structural view of a connecting pipe in the related art, and fig. 2 is a schematic structural view of an intake system in the related art.
Referring to fig. 1 and 2, the engine intake system includes a connecting pipeline 10, a first pipeline 20 and a second pipeline 30, one end of the connecting pipeline 10 is communicated with an air source and a gas source, the other end of the connecting pipeline 10 is communicated with one end of the second pipeline 30, one end of the first pipeline 20 is communicated with the first pipeline 20, the other end of the first pipeline 20 is communicated with an intake pipe of the engine, and the other end of the second pipeline 30 is communicated with the intake pipe of the engine.
The connecting pipeline 10 includes a first connecting section 11, a second connecting section 12 and a transition section 13, and the first connecting section 11 and the second connecting section 12 are uniformly transited through the transition section 13. In this way, air and gas can flow along the inner cavities of the first and second connection sections 11 and 12.
However, because the density of the gas and the air is different, the first connection section 11 and the second connection section 12 are smoothly connected through the transition section 13, so that under the centrifugal action, more air with higher density flows along the outer side of the inner wall of the connection pipeline 10, and gas with lower density flows along the inner side of the inner wall, thereby causing the ratio of the air and the gas entering the first pipeline 20 and the second pipeline 30 to be different, and the concentration of the gas in the first pipeline 20 is greater than that in the second pipeline 30. The mass fraction of the fuel gas in the first pipeline 20 is 19.5% higher than that in the second pipeline 30, which is obtained by CFD (Computational Fluid Dynamics) analysis. Therefore, the mixing uniformity of the air and the gas is poor.
In order to solve the technical problem, the utility model provides a connecting line, air intake system and engine, connecting line includes first linkage segment, second linkage segment and at least one vortex muscle, first linkage segment and second linkage segment intercommunication, and the axis of first linkage segment axis and second linkage segment has the contained angle, and the vortex muscle sets up on the inner wall of first linkage segment, and the extending direction of vortex muscle has the contained angle with the axial of first linkage segment. Or the turbulence ribs are arranged on the inner wall of the second connecting section, and an included angle is formed between the extending direction of the turbulence ribs and the axial direction of the first connecting section. Therefore, the turbulence ribs can break the original flow field of the air and the fuel gas and enhance the turbulence intensity of the air and the fuel gas, so that the air and the fuel gas are mixed uniformly.
Fig. 3 is a schematic structural diagram of a connection pipeline provided in an embodiment of the present invention.
Referring to fig. 3, the present invention provides a connecting pipeline for an air intake system of an engine, the connecting pipeline 100 includes a first connecting section 110, a second connecting section 120 and at least one turbulence rib 130, the first connecting section 110 is communicated with the second connecting section 120, and an included angle is formed between an axis of the first connecting section 110 and an axis of the second connecting section 120.
The spoiler rib 130 is disposed on an inner wall of the first connecting section 110, and an extending direction of the spoiler rib 130 has an included angle with an axial direction of the first connecting section 110.
Or, the spoiler rib 130 is disposed on an inner wall of the second connecting section 120, and an extending direction of the spoiler rib 130 and an axial direction of the first connecting section 110 form an included angle.
When the air-fuel gas mixing device is used, air and fuel gas collide with the turbulence ribs 130 when flowing along the inner cavities of the first connecting section 110 and the second connecting section 120, the turbulence intensity of the air and the fuel gas is enhanced, and the mixing uniformity of the air and the fuel gas is improved.
Compared with the condition that the axis of the first connecting section 110 is parallel to the axis of the second connecting section 120, the occupied space of the connecting pipeline 100 can be reduced under the condition that the length of the first connecting section 110 and the length of the second connecting section 120 are ensured to be constant.
According to the connecting pipeline 100 provided by the embodiment, the first connecting section 110 is communicated with the second connecting section 120 by arranging the first connecting section 110, the second connecting section 120 and the at least one turbulence rib 130, and an included angle is formed between the axis of the first connecting section 110 and the axis of the second connecting section 120. The spoiler rib 130 is disposed on an inner wall of the first connecting section 110, and an extending direction of the spoiler rib 130 has an included angle with an axial direction of the first connecting section 110. Or, the turbulent rib 130 is disposed on the inner wall of the second connection section 120, and an extending direction of the turbulent rib 130 forms an included angle with the axial direction of the first connection section 110. Thus, the turbulence ribs 130 can break the original flow field of the air and the gas, and enhance the turbulence intensity of the air and the gas, thereby achieving the mixing uniformity of the air and the gas.
In a possible implementation manner, the number of the turbulence ribs 130 is at least two, the at least two turbulence ribs 130 include at least one first turbulence rib 131 and at least one second turbulence rib 132, the first turbulence rib 131 is disposed on the inner wall of the first connecting section 110, and the second turbulence rib 132 is disposed on the inner wall of the second connecting section 120.
It can be understood that the air and the gas collide with the first spoiler rib 131 when flowing along the inner cavity of the first connecting section 110 and then collide with the second spoiler rib 132 again when flowing along the inner cavity of the second connecting section 120, so that the turbulence intensity of the air and the gas is increased and the mixing uniformity of the air and the gas is improved.
In some embodiments, the axis of the first spoiler rib 131 is perpendicular to the axis of the first connecting section 110, and the axis of the second spoiler rib 132 is perpendicular to the axis of the second connecting section 120. In this way, the turbulence intensity of the air and the gas can be increased.
Specifically, two ends of the first spoiler rib 131 are correspondingly connected to two opposite sides of the inner wall of the first connecting section 110, and two ends of the second spoiler rib 132 are correspondingly connected to two opposite sides of the inner wall of the second connecting section 120.
In a possible implementation manner, the inner diameter of the first connection section 110 is equal to the inner diameter of the second connection section 120, and the outer diameter of the spoiler rib 130 is 0.3-0.5 times the inner diameter of the first connection section 110.
Illustratively, the turbulator 130 has a diameter that is 0.4 times the inner diameter of the first connection section 110. For example, the inner diameter of the first connection section 110 and the inner diameter of the second connection section 120 are both 250mm, and the outer diameter of the spoiler rib 130 is 100mm.
Specifically, the spoiler rib 130 may have a cylindrical shape.
When the outer diameter of the turbulent rib 130 is less than 0.3 times of the inner diameter of the first connection section 110, the degree of damage of the turbulent rib 130 to the original flow field of air and gas is low.
When the outer diameter of the spoiler rib 130 is greater than 0.5 times the inner diameter of the first connection section 110, pressure loss is large in the air and gas flowing process.
In one possible implementation, the connecting line 100 further includes a transition section 140, one end of the first connecting section 110 is in communication with a first end of the transition section 140, and a second end of the transition section 140 is in communication with an end of the second connecting section 120.
Specifically, the first connection section 110 and the second connection section 120 are uniformly transited by the transition section 140, so that pressure loss is small during the flow of air and gas.
Fig. 4 is a schematic structural diagram of an air intake system according to an embodiment of the present invention.
Referring to fig. 4, the present invention provides an air intake system, which includes a first pipeline 200, a second pipeline 300 and the connection pipeline 100 provided in the above embodiment.
The first end of connecting line 100 is used for communicating with air source and gas source, and the second end of connecting line 100 communicates with the first end of second pipeline 300, and the first end and the connecting line 100 intercommunication of first pipeline 200, the second end of first pipeline 200 and the second end of second pipeline 300 all communicate with the intake pipe of engine, and the vortex muscle 130 of connecting line 100 is located between the first end of connecting line 100 and first pipeline 200.
When the engine is used, air and fuel gas flow along the inner cavities of the first connecting section 110 and the second connecting section 120 and collide with the turbulence ribs 130, the turbulence intensity of the air and the fuel gas is enhanced, the mixing uniformity of the air and the fuel gas is improved, then one part of the air and the fuel gas enters the first pipeline 200, the other part of the air and the fuel gas enters the second pipeline 300, and finally the air and the fuel gas in the first pipeline 200 and the second pipeline 300 enter an air inlet pipe of the engine.
The CFD analysis is performed by taking as an example that the connecting duct 100 includes a first connecting section 110, a second connecting section 120, and a transition section 140. Wherein one end of the first connecting section 110 is communicated with a first end of the transition section 140, a second end of the transition section 140 is communicated with one end of the second connecting section 120, and the first connecting section 110 and the second connecting section 120 are smoothly transited. A first turbulent rib 131 is arranged on the inner wall of the first connection section 110, and the extending direction of the first turbulent rib 131 is perpendicular to the axial direction of the first connection section 110. Meanwhile, a second turbulence rib 132 is arranged on an inner wall of the second connection section 120, and an extending direction of the second turbulence rib 132 is perpendicular to an axial direction of the second connection section 120.
Through the CFD analysis, the mass fraction of the fuel gas in the first pipeline 200 is 0.1% higher than that in the second pipeline 300. Therefore, the mixing uniformity of air and fuel gas in the air inlet system of the engine is good. And the average pressure loss connecting the first end of line 100 to the second end of first line 200 and connecting the first end of line 100 to the second end of second line 300 was 3.3kPa, with a small pressure loss.
The air intake system provided by the present embodiment is formed by providing connecting pipe 100, first pipe 200, and second pipe 300. The first end of connecting line 100 is used for communicating with air source and gas source, and the second end of connecting line 100 communicates with the first end of second pipeline 300, and the first end and the connecting line 100 intercommunication of first pipeline 200, the second end of first pipeline 200 and the second end of second pipeline 300 all communicate with the intake pipe of engine, and the vortex muscle 130 of connecting line 100 is located between the first end of connecting line 100 and first pipeline 200. Thus, the turbulence ribs 130 can break the original flow field of the air and the gas, and enhance the turbulence intensity of the air and the gas, thereby achieving the mixing uniformity of the air and the gas.
