Description

Technical Field

[0002] For different operating conditions of the engine (such as different speeds and torques), it is crucial for the performance of the engine that the exhaust components of the engine can match reasonable exhaust back pressure. In the related art, the engine controls the exhaust back pressure of the engine by adjusting the opening of the valve structure.

This is not conducive to the control of the exhaust emissions of the engine and may make the exhaust back pressure unable to meet the operating requirements of the engine, resulting in limited engine performance.

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] Reference below Figure 1-Figure 2 The exhaust component 100 according to the embodiment of the present utility model is described, and the direction indicated by the arrow in the figure is the flow direction of the airflow in the exhaust component 100.

[0037] refer to Figure 1-Figure 2According to the exhaust component 100 of the first aspect embodiment of the utility model, the exhaust component 100 is used for an engine, and the exhaust component 100 includes: an exhaust pipeline 3 and a regulating mechanism 2, the regulating mechanism 2 includes a regulating pipe 6 and a control component, the exhaust pipeline 3 is connected in series with the regulating pipe 6 and the length of the regulating pipe 6 is adjustable, and the control component is connected to the regulating pipe 6 for adjusting the length of the regulating pipe 6.

[0038] When the length of the regulating tube 6 is extended, the exhaust back pressure of the exhaust component 100 is reduced; when the length of the regulating tube 6 is shortened, the exhaust back pressure of the exhaust component 100 is increased. By flexibly adjusting the length of the regulating tube 6 by the control component, the exhaust back pressure of the exhaust component 100 can be adjusted, and the adjustment range of the exhaust back pressure of the exhaust component 100 is wide.

[0039] Optionally, the exhaust component 100 may be used in a four-cylinder engine but is not limited thereto.

[0040] For example, when the exhaust back pressure required by the engine operating conditions increases, the control component adjusts the length of the regulating tube 6 to shorten the regulating tube 6, so that the exhaust back pressure of the exhaust component 100 increases. The increase in exhaust back pressure is beneficial to increasing the low-speed response of the engine and can effectively cope with scenarios with high intake pressure requirements and engine operating conditions.

[0041] For example, when the exhaust back pressure required by the engine operating conditions is reduced, the control component adjusts the length of the regulating tube 6 to extend the regulating tube 6, so that the exhaust back pressure of the exhaust component 100 is reduced. The reduction in exhaust back pressure is beneficial to suppressing engine combustion knock and other phenomena, and improving the engine combustion performance and fuel consumption level.

[0042] According to the exhaust component 100 of the embodiment of the utility model, by providing an adjustment mechanism 2 including an adjustment tube 6 with adjustable length and a control component, the length of the adjustment tube 6 can be flexibly adjusted through the control component, and the adjustment of the length of the adjustment tube 6 can achieve the adjustment of the exhaust back pressure of the exhaust component 100, so that the adjustment range of the exhaust back pressure of the exhaust component 100 is wide, which is beneficial to improving the control accuracy of the exhaust emission of the engine, and enabling the exhaust component 100 to better meet the needs of different operating conditions of the engine, thereby helping to improve the performance of the engine.

[0043] refer to Figure 2 According to some embodiments of the present invention, at least a portion of the adjusting tube 6 is retractable along the extension direction of the adjusting tube 6 , and the control component is used to drive the adjusting tube 6 to move so as to extend or shorten the adjusting tube 6 .

[0044] Among them, at least part of the adjusting tube 6 is retractable along the extension direction of the adjusting tube 6, which may include the following situations: for example, part of the adjusting tube 6 is retractable along the extension direction of the adjusting tube 6; for another example, the entire adjusting tube 6 is retractable along the extension direction of the adjusting tube 6.

[0045] By making at least a portion of the adjusting tube 6 retractable along the extending direction of the adjusting tube 6 , the length of the adjusting tube 6 is easy to adjust, and the length of the adjusting tube 6 can be conveniently adjusted by controlling the retractable movement of the adjusting tube 6 through the control component.

[0046] refer to Figure 2 According to some optional embodiments of the utility model, the adjustment mechanism 2 includes a housing 20, and the control assembly and at least part of the adjustment tube 6 are located in the housing 20. The control assembly includes a first control member 11 and a second control member 10. The first control member 11 is connected to the adjustment tube 6 and can move relative to the housing 20. The movement of the first control member 11 relative to the housing 20 can drive the adjustment tube 6 to move, so that the adjustment tube 6 is extended or shortened. The second control member 10 is located on a side of the first control member 11 away from the adjustment tube 6. There is a magnetic force between the second control member 10 and the first control member 11 to drive the first control member 11 to move. The magnetic force between the second control member 10 and the first control member 11 is adjustable.

[0047] Among them, at least part of the control component and the regulating tube 6 are located in the shell 20, which may include the following situations: for example, part of the control component and the regulating tube 6 are located in the shell 20; for another example, the control component and the regulating tube 6 are all located in the shell 20.

[0048] Optionally, the first control member 11 and the regulating tube 6 may be fixed by welding, bolting or the like.

[0049] Optionally, the first control member 11 is slidably connected to the shell 20. For example, a guide rail is provided on the shell 20, and a pulley is provided on the first control member 11. The pulley is accommodated in the guide rail and can slide relative to the guide rail, so that the first control member 11 can slide relative to the shell 20 through the pulley and the guide rail.

[0050] For example, the direction of the magnetic force between the first control member 11 and the second control member 10 can be adjusted, and there can be an attractive force between the first control member 11 and the second control member 10, or there can be a repulsive force between the first control member 11 and the second control member 10. By adjusting the direction of the magnetic force between the first control member 11 and the second control member 10, the first control member 11 can be moved closer to or farther from the second control member 10, thereby driving the adjustment tube 6 connected thereto to extend or shorten. For example, the magnitude of the magnetic force between the first control member 11 and the second control member 10 can be adjusted, and by adjusting the magnitude of the magnetic force, the travel of the movement of the first control member 11 can be controlled, thereby adjusting the degree of extension or shortening of the adjustment tube 6.

[0051] By providing a first control member 11 and a second control member 10, and connecting the first control member 11 to the regulating tube 6 and providing the first control member 11 and the second control member 10 with a magnetic force, the magnetic force between the first control member 11 and the second control member 10 can be used as a driving force to control the adjustment of the length of the regulating tube 6, and the magnetic force as a driving force can provide a stable control effect; by making the magnetic force between the first control member 11 and the second control member 10 adjustable, the size and direction of the driving force of the first control member 11 can be changed by adjusting the magnetic force, so that the movement state of the first control member 11 can be stably and accurately controlled, thereby stably and accurately adjusting the length of the regulating tube 6, and further stably and accurately controlling the exhaust back pressure of the exhaust component 100, so that the exhaust component 100 can better meet various different working conditions of the engine.

[0052] According to some optional embodiments of the utility model, the first control member 11 is a permanent magnet, and the second control member 10 is an electromagnet. By making the second control member 10 an electromagnet, the magnitude and direction of the magnetic force between the second control member 10 and the first control member 11 formed as a permanent magnet can be controlled by changing the magnitude and direction of the current input to the second control member 10. For example, the second control member 10 and the first control member 11 can be controlled to generate an attractive force or a repulsive force, so that the second control member 10 can be used to control the first control member 11 to approach or move away, and the first control member 11 can drive the regulating tube 6 connected thereto to extend or shorten, so as to achieve the adjustment of the exhaust back pressure of the exhaust component 100, so that the exhaust component 100 can better meet the different operating conditions of the engine.

[0053] refer to Figure 2According to some optional embodiments of the utility model, the regulating tube 6 is U-shaped and includes a fixed section 7 and two variable sections 8, the fixed section 7 is connected between the two variable sections 8, the variable section 8 is retractable along the extension direction of the variable section 8, the variable section 8 and the control assembly are located on opposite sides of the fixed section 7, the fixed section 7 is connected to the first control member 11, one end of the variable section 8 is connected to the fixed section 7 and the other end is connected to the shell 20. This arrangement enables the fixed section 7 to form a supporting and connecting function between the first control member 11 and the variable section 8, so that the fixed section 7 and the first control member 11 are stably connected and the fixed section 7 can stably transmit the power from the first control member 11 to the two variable sections 8, and by making the two variable sections 8 of the regulating tube 6 retractable along the extension direction of the variable section 8, the first control member 11 can drive the variable section 8 of the regulating tube 6 to retract and extend along the extension direction of the variable section 8, and the variable section 8 can be extended or shortened along its extension direction, so as to adjust the length of the regulating tube 6, thereby adjusting the exhaust back pressure of the exhaust component 100, which is beneficial to improving the performance of the engine under different working conditions.

[0054] Optionally, the fixed section 7 of the regulating tube 6 and the two variable sections 8 can be integrally formed. Optionally, the fixed section 7 of the regulating tube 6 and the two variable sections 8 can be separately arranged, for example, the fixed section 7 and the variable section 8 can be connected by a quick-connect connector or the like.

[0055] refer to Figure 2 According to some optional embodiments of the utility model, the variable section 8 is formed as a bellows. By forming the variable section 8 as a bellows, the bellows has a certain flexibility, so that the length of the variable section 8 formed as a bellows along its extension direction can be flexibly adjusted, so as to flexibly adjust the length of the regulating tube 6; and the bellows can play a role of buffering and shock absorption during the operation of the engine, which can improve the connection stability between the regulating tube 6 and the first control member 11 and the regulating tube 6 and the housing 20.

[0056] refer to Figure 2 According to some optional embodiments of the utility model, the adjustment mechanism 2 further includes a support spring 9, which is arranged in the accommodation space enclosed by the adjustment tube 6, and one axial end of the support spring 9 is connected to the fixed section 7 and the other axial end is connected to the housing 20. By arranging the support spring 9 in the accommodation space enclosed by the adjustment tube 6, the support spring 9 can provide support for the adjustment tube 6, and can reduce or avoid the adjustment tube 6 from twisting and deforming in the housing 20; and the support spring 9 provides auxiliary force for the adjustment tube 6 in the process of the control component driving the adjustment tube 6 to move, so as to achieve more stable control of the length of the adjustment tube 6.

[0057] Optionally, the support spring 9 may be connected to the fixing section 7 by welding; optionally, the support spring 9 may also be connected to the housing 20 by welding.

[0058] Optionally, a plurality of metal support rods may be provided in the shell 20 of the adjustment mechanism 2, and the plurality of metal support rods may be located on the outer peripheral sides of the two variable sections 8, which may also reduce or avoid twisting and deformation of the variable section 8 of the adjustment tube 6 in the shell 20.

[0059] For example, when the exhaust back pressure required by the engine operating conditions increases and the length of the adjusting tube 6 needs to be shortened, the magnetic force between the first control member 11 and the second control member 10 is adjusted to a repulsive force. The magnetic force between the first control member 11 and the second control member 10 drives the first control member 11 to move in a direction away from the second control member 10. The first control member 11 drives the variable section 8 of the adjusting tube 6 to move along its extension direction through the fixed section 7, and compresses the support spring 9 to shorten the length of the adjusting tube 6, thereby increasing the exhaust back pressure in the exhaust component 100.

[0060] For example, when the exhaust back pressure required by the engine operating condition needs to be reduced and the length of the regulating tube 6 needs to be extended, the magnetic force between the first control member 11 and the second control member 10 is adjusted to an attractive force, and the magnetic force between the first control member 11 and the second control member 10 drives the first control member 11 to move in a direction close to the second control member 10. The first control member 11 drives the variable section 8 of the regulating tube 6 to move along its extension direction through the fixed section 7, and causes the support spring 9 to gradually recover, so that the length of the regulating tube 6 is extended, thereby reducing the exhaust back pressure in the exhaust component 100.
