Description
본 고안은 배기매니폴드의 배기가스 유동특성 개선장치에 관한 것이다.The present invention relates to an apparatus for improving exhaust gas flow characteristics of an exhaust manifold.
엔진에서 연소된 배기가스는 배기매니폴드를 거쳐 방출되는데 4실린더 엔진의 경우 도 2에 도시하는 것과 같이 각 실린더에 접속하는 단위 배기매니폴드(1~4)가 2개씩 합하여진 후 최종적으로 하나의 통합된 배기관로(5)를 통해 배출되어지게 되는데 배기매니폴드(1~4)의 통합관로에는 촉매변환기(6)가 접속되어 배기가스중의 유해성분인 HC, CO, Nox 등을 산환환원 반응에 의해 정화처리하게 된다.The exhaust gas combusted by the engine is discharged through the exhaust manifold. In the case of a four cylinder engine, as shown in FIG. 2, two unit exhaust manifolds 1 to 4 connected to each cylinder are added together, and finally one The exhaust gas is discharged through the integrated exhaust pipe (5). The catalytic converter (6) is connected to the integrated pipe of the exhaust manifold (1 to 4) to carry out a redox reaction of HC, CO, Nox, etc., which are harmful components in the exhaust gas. Purification is performed by.
그러나 촉매변환기(6)와 각 배기매니폴드(1~4)의 접속 구조상 배출가스가 폭발순서, 예를들어 4기통 엔진의 경우 1→3→4→2 또는 1→2→4→3의 순서로 배출되기 때문에 서로 간섭을 일으켜 배기가스 유동에 심한 불균형을 가져오고 촉매 변환기(6)의 특정부위에 집중되므로 정화 효율이 저하되는 문제점이 있게 된다.However, due to the connection structure between the catalytic converter 6 and each exhaust manifold 1 to 4, the exhaust gas is exploded in order of explosion, for example, 1 → 3 → 4 → 2 or 1 → 2 → 4 → 3 for a four-cylinder engine. Since it causes the discharge to cause interference with each other to bring about a severe imbalance in the exhaust gas flow and concentrate on a specific portion of the catalytic converter 6 there is a problem that the purification efficiency is lowered.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 배기매니폴드를 통해 배출되는 배기가스가 촉매변환기의 특정 부위로 집중되지 아니하고 고르게 분산되도록 유동분포 특성을 개선하여 정화 효율을 향상시킨 배기매니폴드의 배기가스 유동특성 개선장치를 제공하는데 있다.The present invention has been proposed in view of the above problems, and its purpose is to improve purification efficiency by improving flow distribution characteristics so that the exhaust gas discharged through the exhaust manifold is not concentrated to a specific portion of the catalytic converter and is evenly dispersed. The present invention provides an apparatus for improving exhaust gas flow characteristics of an improved exhaust manifold.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1 은 본 고안에 의한 배기매니폴드의 배기가스 유동특성 개선장치를 나타내는 도면이다.1 is a view showing an apparatus for improving the exhaust gas flow characteristic of an exhaust manifold according to the present invention.
도면중 부호 1~4는 각 실린더의 배기포트에 접속된 단위 배기매니폴드이며 각 배기매니폴드(1~4)가 하나로 통합된 통합관로(5)에는 촉매변환기(6)가 접속되어 있다.In the drawings, reference numerals 1 to 4 denote unit exhaust manifolds connected to the exhaust ports of the respective cylinders, and catalytic converters 6 are connected to the integrated conduit 5 in which the exhaust manifolds 1 to 4 are integrated into one.
그리고 상기 통합관로(5)내에는 각 단위 배기매니폴드(1~4)로부터 엔진점화 순서에 따라 배출되는 배기가스의 층류흐름을 안내하기 위한 복수개의 회동베인(7)이 설치되어 있으며 상기 회동베인(7)은 액츄에이터(8)에 의해 회동각이 제어된다.In addition, a plurality of rotating vanes 7 are installed in the integrated pipe 5 to guide the laminar flow of exhaust gas discharged from the unit exhaust manifolds 1 to 4 in the order of engine ignition. (7), the rotation angle is controlled by the actuator (8).
이와같은 본 고안은 각 실린더의 점화순서에 따라 당해 배기포트에 접속된 배기매니폴드를 통해 배기가스가 배출되어지게 될 때 전자제어장치(9)가 액츄에이터(8)를 구동하여 회동베인(7)을 회동시켜 촉매변환기(6)에 평행하게 안내되는 유동 특성을 갖도록 안내하게 된다.In the present invention, when the exhaust gas is discharged through the exhaust manifold connected to the exhaust port according to the ignition order of each cylinder, the electronic control device 9 drives the actuator 8 to rotate the vane 7. Rotate to guide to have a flow characteristic that is guided parallel to the catalytic converter (6).
이에따라 배기되는 배기가스의 상호 충돌 등의 간섭이 감소되고 유동 관성력에 의해 촉매변환기(6)의 특정 부위로 집중되는 배기가스 흐름이 회동베인(7)의 안내를 받아 촉매변환기(6)에 유도되므로 유동분배 특성이 개선된다.Accordingly, the interference such as the collision of the exhaust gases exhausted is reduced and the exhaust gas flow concentrated to a specific portion of the catalytic converter 6 by the flow inertia is guided to the catalytic converter 6 by the rotation vane 7. Flow distribution characteristics are improved.
이상과 같은 본 고안에 의하면 배기매니폴드의 출구와 촉매변환기 입구 사이의 접속지점에 액츄에이터에 의해 작동되는 회동베인을 각기 설치하는 것에 의하여 배기가스에 평행한 층류 유동을 만들어주데 배기가스 상호간의 간섭 현상을 줄이므로써 유동분배 특성을 개선하여 정화효율을 향상하게 되는 효과가 있다.According to the present invention as described above, by installing a rotary vane operated by an actuator at the connection point between the outlet of the exhaust manifold and the inlet of the catalytic converter, the laminar flow parallel to the exhaust gas is generated. By reducing the flow distribution characteristics are improved to improve the purification efficiency.
