본 발명은 경계층 제어를 통한 써지탱크의 흡기효율 증대구조에 관한 것으로 서, 더욱 상세하게는 항공분야에서 연구중인 흡입(suction)을 이용한 경계층 제어 이론을 자동차에 최초로 적용함으로써, 써지 탱크의 흡기효율을 향상시켜 성능향상을 도모할 수 있도록 한 경계층 제어를 통한 써지탱크의 흡기효율 증대구조에 관한 것이다.The present invention relates to a structure for increasing the intake efficiency of a surge tank through boundary layer control, and more particularly, by applying the boundary layer control theory using suction, which is being studied in the aviation field, for the first time to an automobile, The present invention relates to a structure for increasing the intake efficiency of a surge tank by controlling the boundary layer to improve performance.

차량용 흡기 장치는, 엔진을 작동시키기 위해서 실린더내에 혼합기를 공급하는 장치로서, 에어 크리너, 써지탱크, 흡기 매니폴드 등으로 이루어져 있다. A vehicle intake apparatus is an apparatus for supplying a mixer into a cylinder for operating an engine, and is composed of an air cleaner, a surge tank, an intake manifold, and the like.

상기한 에어 크리너는 엔진에 흡입하는 되는 공기중에 포함되어 있는 먼지와 이물질 등을 제거하는 장치로, 흡기 계통에서 발생하는 흡기 소음을 줄이는 역할도 한다. The air cleaner is a device for removing dust and foreign substances contained in the air that is sucked into the engine, and also serves to reduce intake noise generated in the intake system.

상기한 에어 크리너에서 정화된 공기는 쓰로틀 바디로 유입되는데, 이 쓰로틀 바디 내에는 유입되는 공기의 양을 조절하는 쓰로틀 밸브와, 이 쓰로틀 밸브의 개폐정도를 감지하는 쓰로틀 포지션 센서가 내장 되어 있다. The air purified by the air cleaner is introduced into the throttle body, and a throttle valve for controlling the amount of air introduced therein, and a throttle position sensor for detecting the opening and closing of the throttle valve are built in the throttle body.

상기한 쓰로틀 밸브의 개폐량에 따라 유입 공기의 양이 차이가 나기 때문에 쓰로틀 밸브의 개폐량으로 차속을 결정한다. Since the amount of inlet air is different depending on the opening and closing amount of the throttle valve, the vehicle speed is determined by the opening and closing amount of the throttle valve.

상기한 쓰로틀 바디 후측에 연결된 써지 탱크는 진공압 탱크로서, 실린더 내 피스톤의 행정에 의한 엔진의 부압에 의해 써지 탱크 내를 진공압으로 유지하여 공기를 흡입한다. The surge tank connected to the rear side of the throttle body is a vacuum tank, and the inside of the surge tank is maintained at the vacuum pressure by the negative pressure of the engine by the stroke of the piston in the cylinder to suck in air.

상기한 써지 탱크의 진공압으로 유입된 공기는 흡기 매니폴드로 유입되는데, 이 흡기 매니폴드는 써지 탱크에서 유입되는 공기를 될 수있는 한 저항을 적게하여 실린더 내로 유도하는 관이며, 각 실린더에 균일한 혼합기를 분배하는 역할을 한 다. The air introduced by the vacuum pressure of the surge tank is introduced into the intake manifold. The intake manifold is a tube that guides the air introduced from the surge tank into the cylinder with as little resistance as possible. It serves to dispense one mixer.

이와 같이 이루어진 흡기장치의 공기 흡입 과정을 살펴보면, 에어 크리너에서 정화된 후 쓰로틀 바디로 유입되어 쓰로틀 밸브의 개도율에 따라 그 양이 조절된 후 엔진의 부압에 의해 진공상태인 써지탱크로 압송되어 흡기 매니폴드에서 각각 분배되어 실린더로 유입된다. Looking at the air intake process of the intake device made in this way, after being purified by the air cleaner flows into the throttle body, the amount is adjusted according to the opening ratio of the throttle valve, and then the pressure is supplied to the surge tank which is vacuumed by the negative pressure of the engine to intake air. Each is dispensed from the manifold and flows into the cylinder.

한편, 도 1에 도시한 바와 같이, 상기 써지 탱크(10)의 곡률이 급격하게 변하는 집 튜브(10a)(zip tube)와 플레넘(plenum) 합류부에서 경계층(12)이 크게 형성되게 된다.On the other hand, as shown in Figure 1, the boundary layer 12 is formed large in the confluence of the zip tube 10a (zip tube) and the plenum where the curvature of the surge tank 10 changes rapidly.

미설명 부호 101은 쓰로틀 밸브이다.Reference numeral 101 is a throttle valve.

그러나, 상기 써지 탱크에 유입되는 혼합기는 경계층의 경계면을 따라 유동하게 되므로, 경계층의 두께만큼 실제 혼합기의 유동단면적이 A1에서 A2로 감소하여 흡기 효율 및 성능이 저하되는 문제점이 있다.However, since the mixer flowing into the surge tank flows along the boundary surface of the boundary layer, the flow area of the actual mixer decreases from A1 to A2 by the thickness of the boundary layer, thereby degrading the intake efficiency and performance.

상기 집 튜브의 내부 경계층에 의한 흡기 효율 감소는 실험적 및 이론적으로 널리 알려진 사실이고, 집 튜브 설계시 경계층이 최소로 형성되도록 하기 위해 집 튜브의 곡률을 최소로 할 필요가 있으나, 레이 아웃 상 불가능하여 성능 저하를 감수하고 개발을 진행하고 있는 실정이다.The reduction of intake efficiency by the inner boundary layer of the zip tube is widely known experimentally and theoretically, and it is necessary to minimize the curvature of the zip tube in order to minimize the formation of the boundary layer in the zip tube design. The situation is under development with the performance degradation.

본 발명은 상기와 같은 점을 감안하여 안출한 것으로서, 집 튜뷰 내부에 발달된 경계층을 표면의 흡입홀(suction hole)을 통하여 빨아들여 경계층을 제거함으 로써, 써지탱크의 흡기효율을 향상시켜 성능향상을 도모할 수 있도록 한 경계층 제어를 통한 써지탱크의 흡기효율 증대구조를 제공하는데 그 목적이 있다.The present invention has been made in view of the above, by sucking the boundary layer developed inside the zip tube through the suction hole of the surface to remove the boundary layer, improving the intake efficiency of the surge tank to improve performance The purpose of the present invention is to provide a structure for increasing the intake efficiency of the surge tank through control of the boundary layer.

상기한 목적을 달성하기 위한 본 발명은 집튜브 내부에 경계층이 형성되는 써지탱크에 있어서,The present invention for achieving the above object is a surge tank in which a boundary layer is formed inside the house tube,

상기 경계층이 형성될 집튜브 내부에 흡입홀을 형성하고, 이 흡입홀을 통해 경계층을 흡입하여 제거하는 것을 특징으로 한다.Suction holes are formed in the inner tube in which the boundary layer is to be formed, and the suction layer removes the boundary layer through the suction holes.

바람직한 구현예로서, 상기 써지탱크에 별도로 설치된 진공보조탱크와; 상기 흡입홀과 진공보조탱크를 연결하는 제1연결호스와; 상기 진공보조탱크와 써지탱크를 연결하는 제2연결호스;를 포함하여 구성된 것을 특징으로 한다.In a preferred embodiment, the vacuum auxiliary tank separately installed in the surge tank; A first connection hose connecting the suction hole and the vacuum auxiliary tank; And a second connection hose connecting the vacuum auxiliary tank and the surge tank.

더욱 바람직한 구현예로서, 상기 진공보조탱크는 엔진 작동시 써지탱크에 형성되는 부압으로 진공보조탱크의 공기를 흡입하여 진공이 형성되는 것을 특징으로 한다.In a more preferred embodiment, the vacuum auxiliary tank is characterized in that the vacuum is formed by sucking the air of the vacuum auxiliary tank with a negative pressure formed in the surge tank during the operation of the engine.

또한, 상기 제1 및 제2연결호스에는 각각 제1밸브 및 제2밸브가 장착되는 것을 특징으로 한다.In addition, the first and second connection hoses are characterized in that the first valve and the second valve is mounted.

또한, 상기 제1밸브 및 제2밸브 중 하나는 체크밸브인 것을 특징으로 한다.In addition, one of the first valve and the second valve is characterized in that the check valve.

이하, 본 발명의 바람직한 실시예를 첨부도면을 참조로 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부한 도 2는 본 발명에 따른 써지탱크의 구조를 나타내는 장치구성도이다.2 is a block diagram showing the structure of the surge tank according to the present invention.

본 발명은 쓰로틀 바디 후측에 연결된 써지 탱크(10)의 구조에 관한 것이다.The present invention relates to the structure of the surge tank 10 connected to the rear of the throttle body.

본 발명은 집 튜브(10a)의 내부에 형성되는 경계층(12)이 흡입홀(11) 통해 제거될 수 있도록 한 점에 주안점이 있다.The present invention focuses on the fact that the boundary layer 12 formed inside the collecting tube 10a can be removed through the suction hole 11.

전술한 바와 같이, 써지 탱크(10)는 쓰로틀 바디 후측에 연결되는 진공압 탱크이고, 실린더 내 피스톤의 행정에 의한 엔진의 부압에 의해 써지 탱크(10) 내부가 진공압으로 유지된다.As described above, the surge tank 10 is a vacuum pressure tank connected to the rear side of the throttle body, and the inside of the surge tank 10 is maintained at the vacuum pressure by the negative pressure of the engine by the stroke of the piston in the cylinder.

상기 쓰로틀 바디의 후측에는 써지 탱크의 입구인 집 튜브(10a)가 형성되고, 집 튜브(10a)를 통해 유입되는 혼합기는 플레넘에서 합류되어 흡기 매니폴드로 진입되게 된다.At the rear side of the throttle body, a zip tube 10a, which is an inlet of the surge tank, is formed, and the mixer flowing through the zip tube 10a is joined in the plenum to enter the intake manifold.

그러나 상기 집튜브(10a)는 단면적이 작고 굴곡이 심한데다 집튜브(10a)를 통과하는 혼합기량이 많으므로 혼합기의 이물질이 집튜브(10a) 내부에 쌓여서 경계층(12)이 형성되게 된다.However, since the zip tube 10a has a small cross-sectional area and severe bending and a large amount of the mixture passes through the zip tube 10a, foreign matters of the mixer are piled up inside the zip tube 10a to form the boundary layer 12.

본 발명은 상기 경계층(12)이 형성되는 위치에 형성된 흡입홀(11)과, 흡입홀을 통해 경계층(12)을 빨아 들여 제거하는 경계층 제거수단으로 구성된다.The present invention comprises a suction hole 11 formed at a position where the boundary layer 12 is formed, and boundary layer removing means for sucking and removing the boundary layer 12 through the suction hole.

상기 흡입홀(11)을 통해 경계층(12)을 제거하기 위해 써지탱크(10)와 별도로 진공보조탱크(13)가 써지탱크(10)와 인접한 위치에 설치되고, 이 진공보조탱크(13)는 써지 탱크(10)보다 상대적으로 부피가 작고, 집튜브(10a)의 하부방향으로 배치되는 것이 바람직하다.In order to remove the boundary layer 12 through the suction hole 11, a vacuum auxiliary tank 13 is installed at a position adjacent to the surge tank 10 separately from the surge tank 10, and the vacuum auxiliary tank 13 is disposed. It is preferable that the volume is relatively smaller than that of the surge tank 10 and disposed in the downward direction of the zip tube 10a.

상기 진공보조탱크(13)에는 2개의 연결호스(14,15)가 상부와 하부에 부착되는데, 제1연결호스(14)는 흡입홀(11)과 진공보조탱크(13)를 연결하고, 제2연결호스(15)는 진공보조탱크(13)와 써지탱크(10)의 하부를 연결한다.Two connection hoses 14 and 15 are attached to the upper and lower parts of the vacuum auxiliary tank 13, and the first connection hose 14 connects the suction hole 11 and the vacuum auxiliary tank 13. The two connecting hoses 15 connect the vacuum auxiliary tank 13 and the lower part of the surge tank 10.

즉, 상기 제1 및 제2연결호스(14,15)에 의해 집튜브(10a)의 흡입홀(11)→진공보조탱크(13)→써지탱크(10) 하부가 서로 연통되도록 연결해 준다.That is, the suction holes 11 → vacuum auxiliary tank 13 → surge tank 10 of the zip tube 10a are connected to each other by the first and second connection hoses 14 and 15 so as to communicate with each other.

상기 제1연결호스(14)에는 제1밸브(16)가 삽입되고, 제1밸브(16)에 의해 제1연결호스(14)의 유량을 제어할 수 있고, 제2연결호스(15)에는 제2밸브(17)가 삽입되며, 제2밸브(17)에 의해 제1연결호스(14)의 유량을 제어할 수 있다.The first valve 16 is inserted into the first connection hose 14, the flow rate of the first connection hose 14 can be controlled by the first valve 16, the second connection hose 15 The second valve 17 is inserted, and the flow rate of the first connection hose 14 can be controlled by the second valve 17.

상기 제2밸브(17)는 써지 탱크(10) 하부에서 진공보조탱크(13)로 반대로 흐르지 않도록 역방향으로 흐름을 방지하는 체크밸브인 것이 바람직하다.The second valve 17 is preferably a check valve for preventing the flow in the reverse direction so as not to flow from the lower side of the surge tank 10 to the vacuum auxiliary tank (13).

이와 같은 구성에 의한 본 발명에 따른 경계층 제어를 통한 써지탱크의 흡기효율 증대구조의 작동상태를 설명하면 다음과 같다.Referring to the operation state of the intake efficiency increasing structure of the surge tank through the boundary layer control according to the present invention by such a configuration as follows.

첨부한 도 3은 본 발명에 따른 써지탱크의 작동상태를 나타내는 상태도이다.3 is a state diagram showing an operating state of the surge tank according to the present invention.

엔진이 작동하게 되면 실린더 내 피스톤의 행정에 따른 엔진 부압에 의해 써지탱크(10)의 내부가 진공이 형성되고, 엔진 작동시 써지탱크(10)에 형성된 부압으로 진공보조탱크(13)의 공기를 흡입하여 진공보조탱크(13)에 진공이 형성되게 된다.When the engine is operated, a vacuum is formed in the surge tank 10 by the engine negative pressure according to the stroke of the piston in the cylinder, and when the engine is operated, the air in the vacuum auxiliary tank 13 is discharged by the negative pressure formed in the surge tank 10. By suction, a vacuum is formed in the vacuum auxiliary tank 13.

이때, 체크밸브인 제2밸브(17)에 의해 역방향으로는 공기가 흐를 수 없으므로 진공보조탱크(13)는 항상 진공이 유지되고, 제1밸브(16) 및 제2밸브(17)가 동시에 열릴 경우에도 제1밸브(16)로 들어오는 공기보다 제2밸브(17)로 나가는 공기의 양이 더 많으므로 부압이 유지되게 된다.At this time, since the air cannot flow in the reverse direction by the second valve 17 which is the check valve, the vacuum auxiliary tank 13 is always maintained in vacuum, and the first valve 16 and the second valve 17 are opened at the same time. In this case, since the amount of air going out of the second valve 17 is greater than that of the air entering the first valve 16, the negative pressure is maintained.

상기 집튜브(10a) 내부에 경계층(12)이 형성되고, 경계층(12)에 의한 흡기 효율의 저하로 인해 성능 저하가 발생하므로, 집 튜브(10a) 내에 경계층(12)이 발 달하게 되면, 제1밸브(16)를 열어서 진공탱크(10)의 부압으로 경계층(12)을 흡입하여 제거한다.Since the boundary layer 12 is formed inside the zip tube 10a, and the performance decrease occurs due to the decrease in intake efficiency by the boundary layer 12, when the boundary layer 12 is developed in the zip tube 10a, 1 The valve 16 is opened and the boundary layer 12 is sucked and removed by the negative pressure of the vacuum tank 10.

즉, 상기 진공보조탱크(13)의 내부에 진공이 형성됨에 따라 제1밸브(16)를 열게 되면 집튜브(10a)의 내부에 형성된 경계층(12)이 흡입홀(11)을 통해 제1연결호스(14)로, 제1연결호스(14)에서 진공보조탱크(13)로 이동하게 된다.That is, when the first valve 16 is opened as a vacuum is formed in the vacuum auxiliary tank 13, the boundary layer 12 formed inside the zip tube 10a is connected to the first through the suction hole 11. With the hose 14, it moves from the first connecting hose 14 to the vacuum auxiliary tank (13).

계속해서 진공보조탱크(13)에 저장된 경계층(12)이 제2연결호스(15)를 통해 써지탱크(10)의 하부로 분산되게 된다.Subsequently, the boundary layer 12 stored in the vacuum auxiliary tank 13 is distributed to the lower portion of the surge tank 10 through the second connection hose 15.

따라서, 써지탱크(10)에 형성된 부압으로 진공보조탱크(13)에 진공이 형성하고, 진공보조탱크(13)의 부압에 의해 집튜브(10a) 내부의 경계층(12)이 흡입홀(11)을 통해 제거될 수 있다.Therefore, a vacuum is formed in the vacuum auxiliary tank 13 by the negative pressure formed in the surge tank 10, and the boundary layer 12 inside the zip tube 10a is sucked by the negative pressure of the vacuum auxiliary tank 13. Can be removed via

이상에서 본 바와 같이, 본 발명에 따른 경계층 제어를 통한 써지탱크의 흡기효율 증대구조에 의하면, 써지탱크에 형성된 부압으로 진공보조탱크에 진공이 형성하고, 진공보조탱크의 부압에 의해 집튜브 내부의 경계층이 흡입홀을 통해 제거됨으로써, 써지탱크의 흡기효율 및 성능향상을 도모할 수 있다.As described above, according to the structure of the intake efficiency of the surge tank through the boundary layer control according to the present invention, the vacuum is formed in the vacuum subsidiary tank with the negative pressure formed in the surge tank, the internal pressure of the vacuum secondary tank By removing the boundary layer through the suction hole, the intake efficiency and performance of the surge tank can be improved.
