도 1 및 도 2를 참조하면, 본 발명의 일 실시례에 따른 내연기관의 와류 발생기(100)는 외경관부(110), 내경부(120) 및 와류 날개(130)를 포함할 수 있다. 1 and 2, the vortex generator 100 of the internal combustion engine according to an embodiment of the present invention may include an outer diameter tube portion 110, an inner diameter portion 120, and a vortex blade 130.

본 발명에 따른 내연기관의 와류 발생기(100)는 외부에서 흡입되는 한 부분 또는 흡입되는 공기를 공급한 후 엔진룸을 거쳐 배기관으로 배출되도록 하는 흡·배기관의 한 부분에 설치되어, 자동차 등의 내연기관이 흡입하여 배기되는 공기가 와류를 형성하도록 한다. 또한 본 발명에 따른 와류날개를 가지는 내연기관의 와류 발생기(100)는 내연기관이 공기를 흡입하는 부분의 엔진과 배기하는 부분의 사이에서 다양한 위치를 선택하여 설치할 수 있다.The vortex generator 100 of the internal combustion engine according to the present invention is installed in a part of an intake / exhaust pipe for supplying a part sucked from outside or air to be sucked and then discharged to an exhaust pipe through an engine room, Allow the air to be sucked and exhausted by the engine to form a vortex. Further, the vortex generator 100 of the internal combustion engine having the vortex blades according to the present invention may be installed at various positions between the engine and the exhausting portion of the portion where the internal combustion engine sucks air.

외경관부(110)은 내연기관의 엔진과 외부 사이에 설치되는 흡배기관 내에 설치되는데, 관형으로 이루어짐으로써 중공부재로 이루어지게 되고, 금속재질을 비롯하여 통과하는 공기의 온도를 고려하여 내열이 가능한 재질로 이루어질 수 있다.The outer diameter tube portion 110 is provided in an intake and exhaust pipe provided between the engine and the outside of the internal combustion engine. The outer diameter tube portion 110 is made of a hollow member by a tubular shape. The outer diameter tube portion 110 is made of a metal material and a heat- Lt; / RTI >

외경관부(110)은 내주면에서 와류 날개(130)의 볼록면(131)이 접하는 측에 가이드홈(111)이 형성된다. 이러한 가이드홈(111)은 공기가 와류를 형성할 경우, 와류 날개(130)의 볼록면과 외경관부(110)의 내주면 연결 부위에 충돌을 일으키게 되는데, 이때 공기와의 충돌로 인한 정체를 최소화하여, 원활한 공기의 통과에 도움을 주도록 한다.  The outer diameter tube portion 110 is formed with a guide groove 111 on the side where the convex surface 131 of the vortex vane 130 is in contact with the inner circumferential surface. When air forms a vortex, the guide groove 111 collides with the convex surface of the vortex 130 and the inner circumferential surface connecting portion of the outer diameter tube portion 110. At this time, stagnation due to collision with air is minimized , Helping to pass smooth air.

내경부(120)은 외경관부(110)의 내부에 외경관부(110)과 동심원을 이루도록 위치하는데, 바람직하게는 관형이 아닌 링부재로 이루어짐으로써 외경관부(110) 내부에서 차지하는 부피가 최소화되어, 공기의 흐름에 미치는 간섭을 최소화하도록 하면서, 다수의 와류 날개(130)가 정해진 자세를 유지하도록 고정 지지하는 역할을 한다. The inner diameter portion 120 is disposed concentrically with the outer diameter tube portion 110 within the outer diameter tube portion 110. The inner diameter portion 120 is preferably made of a non-tubular ring member, so that the volume occupied inside the outer diameter tube portion 110 is minimized, And serves to fix and support the vortex vanes 130 so as to maintain the predetermined attitude while minimizing the interference on the air flow.

도 3 및 도 4를 참조하면, 와류 날개(130)는 다수, 예컨대 3개로 이루어져서, 내경부(120)에 연결되어 나선형태로 곡률을 가짐과 동시에 경사지도록 형성되어 외경관부(110)의 내주면에 연결됨으로써, 외경관부(110)을 통과하는 공기에 와류를 형성하도록 하고, 곡률이 변하도록 꺾임부(135)가 형성된다. 여기서, 와류 날개(130)는 꺾임부(135)에 의해, 2단으로 형성되어, 3 and 4, the vortex vane 130 includes a plurality of, for example, three vortex blades 130 connected to the inner diameter portion 120 and having a curvature in a spiral shape and being inclined, and is formed on the inner peripheral surface of the outer diameter tube portion 110 Thereby forming a vortex in the air passing through the outer diameter tube portion 110, and a bending portion 135 is formed so that the curvature changes. Here, the vortex blade 130 is formed in two stages by the bending portion 135,

와류 날개(130) 각각은 앞서 설명한 바와 같이, 동일한 방향의 나선형태로 곡률을 가지되, 공기의 통과방향을 기준으로 전체적으로 경사각(α)을 가지고서 일정한 높이를 가지도록 마련되어, 내경부(120)을 매개로 서로 연결되는데, 외경관부(110)을 통과하는 공기의 흐름이 와류를 형성하도록 하여, 효과적인 유동 박리 현상을 감소시키고, 이로 인해 공기의 흐름이 원활하도록 하여 소음을 감소시키도록 한다. As described above, each of the vortex blades 130 has a curvature in the same direction as a spiral shape and has a constant height with an inclination angle? As a whole based on the passage direction of the air, The flow of air passing through the outer diameter tube portion 110 forms a vortex so as to reduce the effective flow separation phenomenon and thereby to smooth the flow of air to reduce the noise.

한편, 와류 날개(130)는 나선형태의 곡률을 가짐으로써, 일측면에 볼록하게 형성되는 볼록면(131)이 형성되고, 그 반대측면에 오목하게 형성되는 오목면(132)이 형성된다.On the other hand, the vortex vane 130 has a spiral curvature to form a convex surface 131 convex on one side, and a concave surface 132 concave on the opposite side.

와류 날개(130)는 내경부(120)이 연결되는 단부에 볼록면(131)이 향하는 측으로 돌출되어, 와류 형성의 시작을 가이드하는 제 1 가이드돌기(133)가 형성될 수 있다. 따라서, 제 1 가이드돌기(133)에 의해 공기의 와류 형성에 도움을 주도록 함으로써, 와류 형성 효율을 증강시키는 역할을 한다. The vortex blade 130 may be formed with a first guide protrusion 133 protruding toward the convex surface 131 toward the end where the inner diameter portion 120 is connected to guide the start of vortex formation. Accordingly, the first guide protrusion 133 helps air vortex formation, thereby enhancing vortex formation efficiency.

와류 날개(130)는 외경관부(110)이 연결되는 단부에서 오목면(132) 측에 가이드홈(111)으로의 공기 흐름을 가이드하는 제 2 가이드돌기(134)가 형성된다. 따라서, 공기가 와류를 형성시, 제 2 가이드돌기(134)에 가이드되어 가이드홈(111)을 따라 원활하게 통과하도록 한다. 여기서 제 2 가이드돌기(134)는 공기의 흐름을 가이드하도록 본 실시례에서처럼 와류 날개(130)의 단부 두께를 급격히 증가시키는 돌기 구조를 가질 수 있다. The vortex blade 130 has a second guide protrusion 134 for guiding the air flow from the concave surface 132 side to the guide groove 111 at the end where the outer diameter tube portion 110 is connected. Therefore, when air is formed in the vortex, it is guided by the second guide protrusion 134 and smoothly passes along the guide groove 111. Here, the second guide protrusion 134 may have a protruding structure for rapidly increasing the end thickness of the vortex vane 130 as in the present embodiment to guide the flow of air.

와류 날개(130)는 외경관부(110)의 내주면에 인접하는 측의 두께(d2)가 상기 내경부(120)의 외주면에 인접하는 측의 두께(d1)보다 두껍도록 형성될 수 있다. 따라서, 와류 날개(130)에서 볼록면(131)과 오목면(132) 간에 압력 차이를 증가시키고, 이로 인해 볼록면(131)과 오목면(132) 간의 공기 유속의 차이를 증가시킴으로써, 와류 형성력에 도움을 주고, 이로 인해 와류의 형성력을 증가시키도록 할 수 있다. 와류 날개(130)는 상기한 바와 같은 와류 형성 효율의 증대로 인해, 공기의 흐름이 원활하도록 함으로써, 별도의 터보를 설치하지 않아도 터보 과급기의 역할을 수행할 수 있도록 한다.The vortex blade 130 may be formed such that the thickness d2 of the side adjacent to the inner peripheral surface of the outer diameter tube portion 110 is thicker than the thickness d1 of the side adjacent to the outer peripheral surface of the inner diameter portion 120. [ Thus, by increasing the pressure differential between the convex surface 131 and the concave surface 132 in the vortex vane 130 and thereby increasing the difference in air velocity between the convex surface 131 and the concave surface 132, , Thereby increasing the formation capacity of the vortex. The vortex vanes 130 facilitate the flow of air due to the increase of the vortex formation efficiency as described above, thereby performing the role of the turbocharger without providing a separate turbo.

도 5을 참조하면, 본 발명에 따른 내연기관의 와류 발생기는 외경관부의 직경이나 내경부의 직경 등을 비롯하여, 내연기관의 흡기관 규격에 따라 그 치수를 여러 가지로 달리할 수 있음을 나타내며, 이로 인해 설치 규격의 상이함은 물론, 증강 출력의 크기 역시 달리할 수 있음은 물론이다.Referring to FIG. 5, the vortex generator of the internal combustion engine according to the present invention may have various dimensions depending on the diameter of the outer diameter tube portion, the diameter of the inner diameter portion, and the like of the internal combustion engine. Therefore, it is needless to say that the size of the reinforcement output can be varied as well as the installation standard is different.

이와 같은 본 발명에 따른 내연기관의 와류 발생기에 따르면, 와류 날개가 꺾임부에 의해 2단으로 형성되도록 하여, 공기를 분산시켜서 와류 형성량을 증가시킬 수 있다.According to the vortex generator of the internal combustion engine according to the present invention, the vortex vanes are formed in two stages by the bent portions, so that the amount of vortex formation can be increased by dispersing the air.

본 발명에 따르면, 와류 날개의 두께가 외경관부 측이 두껍게 형성되도록 함으로써, 와류 날개의 볼록면과 오목면 사이의 공기 속도 차이를 증가시켜서 와류 형성력을 증대시킬 수 있으며, 외경관부의 내측면에 와류 날개에 의해 형성되는 와류가 정체되는 것을 해소하도록 가이드홈이 형성됨으로써 와류의 원활한 흐름을 보장할 수 있다.According to the present invention, the thickness of the vortex blade is formed to be thick on the outer diameter tube portion side, thereby increasing the air velocity difference between the convex surface and the concave surface of the vortex blade to increase the vortex formation force, The guide grooves are formed to eliminate stagnation of the vortex formed by the wings, thereby ensuring smooth flow of the vortex.

본 발명에 따르면, 이러한 점들로 인해 공기의 흐름을 원활하게 하여 연소효율을 증대시켜 연비를 향상시킬 수 있으며, 매연을 감소할 수 있고, 엔진의 수명연장과 소음을 감소시킬 수 있다.According to the present invention, it is possible to improve the fuel efficiency by improving the combustion efficiency by smoothly flowing the air through these points, reducing the soot, extending the life of the engine and reducing the noise.
