Description
본 고안은 배기매니폴드의 배기가스 유동개선장치에 관한 것으로서, 특히 믹싱배기파이프의 내측으로 진동발생기능을 갖는 돌출형의 스월제너레이터(Swirl generator)를 설치하고 외측으로 열을 발생시키는 히터를 설치하여 배기매니폴드에서 배출되는 배기가스가 믹싱배기파이프를 지날 때, 뒷쪽으로 재순환되는 등의 흐름을 최대한 억제하여 배기가스의 흐름을 일정하게 유지함으로써, 담체내에서의 배기가스 유동을 균일하게 유지할 수 있고, 이에 따라 담체의 배기가스 정화효율을 높일 수 있도록 한 배기매니폴드의 배기가스 유동개선장치에 관한 것이다.The present invention relates to an exhaust gas flow improving device of an exhaust manifold, and in particular, by installing a swirl generator having a vibration generating function inside the mixing exhaust pipe and installing a heater to generate heat to the outside. When the exhaust gas discharged from the exhaust manifold passes the mixing exhaust pipe, the flow of the exhaust gas is uniformly restrained and the exhaust gas is kept constant so that the exhaust gas flow in the carrier can be uniformly maintained. Accordingly, the present invention relates to an exhaust gas flow improving apparatus of an exhaust manifold that can increase the exhaust gas purification efficiency of a carrier.
일반적으로 자동차 엔진에서 배출되는 배기가스는 배기매니폴드를 거쳐서 배기를 이동시켜주는 배기파이프를 거쳐 담체라고 하는 촉매가 내장된 부분에서 인체에 유해하고 대기를 오염시키는 물질이 제거되어진 상태로 소음기를 거쳐 외부로 배출되는 것이다.In general, exhaust gas emitted from an automobile engine passes through an exhaust pipe that moves exhaust through an exhaust manifold, and then passes through a silencer in a state where harmful substances to the human body and air pollutants are removed from a portion containing a catalyst called a carrier. It is discharged to the outside.
이와 같이, 담체에 내장된 촉매는 배기매니폴드를 거쳐 외부로 배출되는 배기가스가 이동하기만 하면 배기가스와 촉매변환을 일으키게 되어 배기가스를 정화시키게 되는 것으로서, 이동되는 배기가스의 이동상태를 촉매의 배기가스 정화효율에 많은 영향을 끼친다.As described above, the catalyst embedded in the carrier causes the catalytic conversion with the exhaust gas as long as the exhaust gas discharged to the outside through the exhaust manifold is moved, thereby purifying the exhaust gas. Has a great effect on the exhaust gas purification efficiency.
도 1은 종래의 일반적인 배기매니폴드에서 배기가스가 배출되는 상태를 보여주는 개략도이다.1 is a schematic view showing a state in which exhaust gas is discharged from a conventional general exhaust manifold.
엔진(1)의 실린더에서 폭발되면서 발생되는 배기가스는 4기통 엔진의 경우에는 4개의 매니폴드(2)에서 순차적으로 배출되어지며, 도 1에서는 가장 마지막에는 배기매니폴드(2)를 통하여 배기가스가 배출되는 상태를 보여주고 있다.The exhaust gas generated by the explosion of the cylinder of the engine 1 is sequentially discharged from the four manifolds 2 in the case of the four-cylinder engine, and the exhaust gas is exhausted through the exhaust manifold 2 at the end in FIG. Shows the state of discharge.
이와 같이, 배기매니폴드(2)의 가장 마지막 파이프를 통하여 믹싱배기파이프(3)로 배기가스가 유입되어지게 되면, 배기경로(4)로 표시된 부분에서와 같이 배기가스는 배기파이프(3)의 측벽부분에 부딪히면서 뒷쪽으로 재순환되는 등, 즉 배기가스의 재순환영역이 불가피하게 발생하게 되는 등 전반적으로 그 흐름이 균일하지 않게 되고, 이로 인해 담체로 유입되는 배기가스의 유동이 담체의 전체 면적에 걸쳐 균일하지 않게 되므로, 담체의 배기가스 정화효율이 떨어지는 단점이 있었다.In this way, when the exhaust gas is introduced into the mixing exhaust pipe 3 through the last pipe of the exhaust manifold 2, the exhaust gas is exhausted from the exhaust pipe 3 as shown in the portion indicated by the exhaust path 4. The flow of the exhaust gas flowing into the carrier is not uniform throughout the carrier, such that it is recycled to the back while hitting the side wall portion, that is, an inevitably occurs in the recycle zone of the exhaust gas. Since it is not uniform, there was a disadvantage in that the exhaust gas purification efficiency of the carrier is lowered.
본 고안은 이러한 점을 감안하여 안출한 것으로서, 믹싱배기파이프의 내외측으로 진동발생기능을 갖는 돌출형의 스월제너레이터와 열을 발생시키는 히터를 설치하여 배기매니폴드에서 배출되는 배기가스가 믹싱배기파이프 내에서 뒷쪽으로 재순환되는 흐름을 억제할 수 있도록 함으로써, 담체로 유입되는 배기가스가 담체의 전체 면적에 걸쳐 골고루 퍼지면서 그 유동이 균일하게 이루어질 수 있도록 하고, 이에 따라 전체적인 배기가스 정화효율을 향상시킬 수 있도록 하는데 그 목적이 있는 것이다.The present invention has been devised in view of this point, and the exhaust gas discharged from the exhaust manifold is installed inside the mixing exhaust pipe by installing a swirl generator having a vibration generating function and a heater generating heat to the inside and outside of the mixing exhaust pipe. By suppressing the flow recycled to the rear from the back, the exhaust gas flowing into the carrier can be spread evenly over the entire area of the carrier, so that the flow can be made uniform, thereby improving the overall exhaust gas purification efficiency. The purpose is to make it.
이러한 목적은 배기매니폴드를 통하여 믹싱배기파이프로 이동하는 배기가스를 담체내의 촉매로 정화시키는 장치에서, 상기 믹싱배기파이프의 내측에 설치되고 제어부의 제어를 받아 이동하는 배기가스에 진동을 가함과 더불어 돌출형 구조를 통해 배기가스의 흐름을 가로막는 스월제너레이터와, 상기 스월제너레이터와 제어부 간의 제너레이터배선과, 상기 믹싱배기파이프의 외측에 설치되고 제어부의 제어를 받아 공회전 워밍업시의 배기가스에 열을 가하여 온도를 높여주는 히터와, 상기 히터와 제어부 간의 히터배선으로 구성된 배기매니폴드의 배기가스 유동개선장치를 제공함으로써 달성된다.The purpose of the present invention is to provide an apparatus for purifying exhaust gas moving to a mixing exhaust pipe through an exhaust manifold with a catalyst in a carrier, and to oscillate the exhaust gas installed inside the mixing exhaust pipe and controlled by a control unit. A swirl generator that blocks the flow of exhaust gas through the protruding structure, a generator wiring between the swirl generator and the control unit, and is installed outside the mixing exhaust pipe and is controlled by the control unit to apply heat to the exhaust gas during idling warm-up to control the temperature. It is achieved by providing an exhaust gas flow improving device of the exhaust manifold composed of a heater to increase the heater, and the heater wiring between the heater and the control unit.

이하, 첨부한 도면에 의거하여 본 고안의 구성에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the present invention.
도 2에 도시한 바와 같이, 본 고안에 따른 배기매니폴드의 배기가스 유동개선장치의 구성은 배기매니폴드(20)를 통하여 믹싱배기파이프(30)로 이동하는 배기가스를 담체(70) 내의 촉매로 정화시키는 장치에 있어서, 상기 믹싱배기파이프(30)의 내측에 설치되고 제어부(60)의 제어를 받아 이동하는 배기가스에 진동을 가함과 더불어 돌출형 구조를 이용하여 배기가스가 뒷쪽으로 재순환되는 것을 억제하는 스월제너레이터(40) 및 제어부(60)와의 연결을 위한 제너레이터배선(42)과, 상기 믹싱배기파이프(30)의 외측에 설치되고 제어부(60)의 제어를 받아서 공회전 워밍업시의 배기가스에 열을 가하여 온도를 높여주는 히터(50) 및 제어부(60)와의 연결을 위한 히터배선(52)으로 구성된다.As shown in Figure 2, the configuration of the exhaust gas flow improvement device of the exhaust manifold according to the present invention is a catalyst in the carrier 70 to transfer the exhaust gas to the mixing exhaust pipe 30 through the exhaust manifold 20 In the apparatus for purifying the furnace, the exhaust gas is recycled to the rear side by using a protruding structure while applying vibration to the exhaust gas which is installed inside the mixing exhaust pipe 30 and is controlled by the controller 60. Generator wiring 42 for connection with the swirl generator 40 and the control unit 60 for suppressing the control, and the exhaust gas during idling warm-up under the control of the control unit 60 and installed outside the mixing exhaust pipe 30. It is composed of a heater wiring 52 for connecting the heater 50 and the control unit 60 to increase the temperature by applying heat to.
그리고, 상기 스월제너레이터(40)는 담체(70)을 향하여 내측으로 경사지도록 설치되어서, 담체(70)쪽을 향하는 배기가스의 흐름을 방해하지 않으면서 배기매니폴드(20)쪽으로 재순환되려는 배기가스의 흐름에 간섭을 줄 수 있도록 구성된다.In addition, the swirl generator 40 is installed to be inclined inwardly toward the carrier 70, so that the swirl generator 40 is recycled toward the exhaust manifold 20 without disturbing the flow of the exhaust gas toward the carrier 70. It is configured to interfere with the flow.
한편, 상기 믹싱배기파이프(30)의 외측으로 설치되는 히터(50)는 전열코일드을 믹싱배기파이프(30)의 외주면에 감싸거나 통상적으로 사용되는 적절한 방법을 사용하도록 한다.On the other hand, the heater 50 installed to the outside of the mixing exhaust pipe 30 is to wrap the heat transfer coil on the outer peripheral surface of the mixing exhaust pipe 30 or to use a suitable method commonly used.
이하, 본 고안의 작용을 개략적으로 살펴보도록 한다.Hereinafter, look at the operation of the present invention schematically.
먼저, 본 고안의 사용상태를 살펴보게 되면, 자동차를 가동시키면, 엔진을 공회전상태로 워밍업하면서 발생된 배기가스가 적절한 온도로 배출되도록 제어부(60)에서 히터배선(52)를 통하여 히터(50)의 온도를 올려주어 담체(70)로 유입되는 배기가스가 원활하게 정화되도록 한다.First, looking at the use state of the present invention, when the vehicle is operated, the heater 50 through the heater wiring 52 in the control unit 60 so that the exhaust gas generated while warming up the engine to idle state is discharged to an appropriate temperature By raising the temperature of the exhaust gas flowing into the carrier 70 is smoothly purified.
즉, 엔진 워밍업시 배기가스의 온도를 높여주는 방법으로 담체(70)의 온도를 짧은 시간 내에 정상적으로 활성화되는 적정수준까지 올려줌으로써, 담체(70)의 정화성능이 향상될 수 있게 된다.That is, by raising the temperature of the carrier 70 to a proper level that is normally activated within a short time by increasing the temperature of the exhaust gas during the engine warm-up, the purification performance of the carrier 70 can be improved.
그리고, 워밍업이 끝나고 정상적인 운행상태에서 엔진에서 발생되는 배기가스가 배기매니폴드(20)를 통하여 도 2의 화살표 방향으로 이동하게 되고, 믹싱배기파이프(30)의 내측에 설치되어 있는 스월제너레이터(40)에 제어부(60)에 의한 제너레이터배선(42)을 통해 전류를 공급하게 되면, 스월제너레이터(40)가 작동되면서 배기가스는 담체(70) 쪽으로 균일하게 유동될 수 있게 된다.Then, after the warm-up is completed, the exhaust gas generated in the engine in the normal running state is moved in the direction of the arrow of FIG. 2 through the exhaust manifold 20, and the swirl generator 40 installed inside the mixing exhaust pipe 30. When the current is supplied to the generator through the generator wiring 42 by the controller 60, the swirl generator 40 is operated to allow the exhaust gas to flow uniformly toward the carrier 70.
즉, 믹싱배기파이프(30)의 내측에서 담체(70)쪽을 향해 경사진 상태로 일정길이 돌출되어 있는 스월제너레이터(40)가 진동을 발생시키게 되면, 그 돌출된 부위의 주위로 진동에 의해 정체되는 소정의 배기가스 막이 형성되고, 이에 따라 배기매니폴드(20) 쪽으로 재순환되려는 배기가스가 상기 배기가스 막에 의해 차단되면서 재차 그 흐름이 바뀌어 담체(70)측으로 유동될 수 있게 되므로, 담체(70) 내에서의 배기가스 유동이 담체(70) 전체 면적에 걸쳐 균일하게 이루어질 수 있게 되는 것이다.That is, when the swirl generator 40 which protrudes a predetermined length in a state inclined toward the carrier 70 from the inside of the mixing exhaust pipe 30 generates vibration, it is stagnated by the vibration around the protruding portion. Since a predetermined exhaust gas film is formed, and thus the exhaust gas to be recycled toward the exhaust manifold 20 is blocked by the exhaust gas film, its flow can be changed again and flowed to the carrier 70. Exhaust gas flow in the c) can be made uniform over the entire area of the carrier (70).
이에 따라, 종전과 같은 배기가스의 재순환 영역을 없애고 담체(70) 내에서의 배기가스 유동이 균일하게 이루어질 수 있도록 함으로써, 배기가스 정화효율을 높일 수 있게 되는 것이다.Accordingly, by eliminating the recirculation region of the exhaust gas as in the past and allowing the exhaust gas flow in the carrier 70 to be uniform, the exhaust gas purification efficiency can be increased.
이상에서와 같이 본 고안은 믹싱배기파이프의 내측에 설치되는 진동발생기능을 갖는 돌출형의 스월제너레이터를 포함하는 배기매니폴드의 배기가스 유동개선장치를 제공함으로써, 믹싱배기파이프 내에서 재순환되는 배기가스의 흐름을 최대한 억제할 수 있고, 이에 따라 담체 내에서의 배기가스의 흐름을 균일하게 유지하여 배기가스 정화효율을 향상시킬 수 있는 장점이 있으며, 또한 히터를 이용하여 공회전 워밍업시에 믹싱배기파이프에 열을 가하므로 배기가스의 온도를 향상시켜 정화효율을 높일 수 있는 효과가 있는 것이다.As described above, the present invention provides an exhaust gas flow improving device for an exhaust manifold including a protrusion swirl generator having a vibration generating function installed inside the mixing exhaust pipe, whereby the exhaust gas is recycled in the mixing exhaust pipe. Can be suppressed as much as possible, thereby maintaining a uniform flow of exhaust gas in the carrier, thereby improving the exhaust gas purification efficiency, and also using a heater to mix the exhaust pipe during idling warm-up. By applying heat, the temperature of the exhaust gas is improved, thereby improving the purification efficiency.
