Description

EGR밸브 장착구조EGR valve mounting structure

본 고안은 인테이크 매니폴드에 일체형으로 형성되도록 하여 가스의 리크(Leak)를 방지하고, 제작비가 절감되도록 하는 EGR밸브 장착구조에 대한 것이다.The present invention relates to an EGR valve mounting structure that is formed integrally with the intake manifold to prevent leakage of gas and to reduce manufacturing costs.

배기가스 재순환 장치(Exhaust Gas Recirculation, 약칭해서 EGR이라 함)는 배기가스 중의 일부를 익조스트 매니폴드(Exhaust Manifold) 하부로부터 유출시켜 이를 인테이크 매니폴드(Intake Manifold)로 공급되도록 하므로서 연료와 공기의 혼합기와 혼합되도록 하여 이를 다시 연소실로 공급시켜 재연소되도록 하는 것이다.Exhaust gas recirculation (abbreviated as EGR) causes some of the exhaust gas to flow out of the bottom of the exhaust manifold so that it is fed to the intake manifold, thus mixing the fuel and air It is mixed with and is fed back into the combustion chamber to be reburned.

배기가스가 재순환하게 되면 새혼합기의 충진율은 낮아지게 되고, 재공급된 배기가스는 질소에 비해서 열 용량이 큰 탄산가스를 다량으로 함유하게 되므로 더이상 연소작용을 할 수 없기 때문에 동력 행정시의 연소온도를 낮게 형성시키면서 질소 산화물의 생성을 현저하게 감소시키게 된다.When the exhaust gas is recycled, the filling rate of the new mixer is lowered, and since the re-supplied exhaust gas contains a large amount of carbon dioxide gas having a larger heat capacity than nitrogen, the combustion temperature at the power stroke can no longer be operated. Forming a low reduces the production of nitrogen oxides significantly.

상기와 같은 질소 산화물의 생성을 억제시키기 위해 차량에 설치되는 배기가스 재순환 장치에는 익조스트 매니폴드로부터 도입되는 배기가스의 공급을 단속 제어토록 하는 EGR밸브를 도 3에서와 같이 인테이크 매니폴드(1)에 장착시키게 되는바 현재는 인테이크 매니폴드(1)에 2개의 볼트(11)를 사용하여 체결 고정되도록 하고 있다.The exhaust gas recirculation apparatus installed in the vehicle for suppressing the generation of nitrogen oxides as described above includes an intake manifold (1) having an EGR valve for intermittently controlling the supply of the exhaust gas introduced from the ixost manifold. Currently, two bolts 11 are used to fasten and fix the intake manifold 1.

하지만 상기의 EGR밸브(10)는 별도로 제작되어 독립된 조립공정을 통해 볼트(11)로 체결시켜야만 하므로 제작 및 장착이 번거롭고, 특히 비용이 많이 들며, 장시간 사용시 가스가 외부로 리킹(Leaking)되는 문제점이 있다.However, since the EGR valve 10 is manufactured separately and must be fastened to the bolt 11 through an independent assembly process, manufacturing and mounting are cumbersome, particularly expensive, and the problem of leaking gas to the outside when used for a long time is problematic. have.

이에 본 고안은 상기한 문제점을 개선시키기 위하여 인테이크 매니폴드의 제작시 밸브 홀을 일체로 형성하고, 밸브 홀 내부로는 부품만을 삽입시킨 후 밀폐시켜 장착되도록 하므로서 제작 및 장착에 따른 원가가 절감되고, 영구적인 사용을 가능케하는 동시에 외부로 배기가스 리크를 방지될 수 있도록 하는 EGR밸브를 제공코자 하는데 본 고안의 주된 목적이 있다.In this regard, the present invention forms a valve hole integrally when fabricating an intake manifold to improve the above problems, and inserts only a part into the valve hole to seal and mount the valve hole, thereby reducing the cost of manufacturing and mounting. The main object of the present invention is to provide an EGR valve that enables permanent use and at the same time prevents leakage of exhaust gas to the outside.

또한 본 고안은 EGR밸브를 외부로 노출시키지 않게 되므로 엔진 룸내 다른 부품들의 장착에 따른 간섭을 줄이면서 미관이 개선되도록 하는데 다른 목적이 있다.In addition, since the present invention does not expose the EGR valve to the outside, it is another object to improve the aesthetics while reducing the interference caused by the mounting of other components in the engine room.

이를 첨부한 실시예 도면을 참조하여 보다 상세하게 설명하면 도 1에서 보는바와 같이 본 고안은 인테이크 매니폴드(1)의 인렛 홀(2)과 아웃렛 홀(3)이 연통되게 밸브 홀(4)이 일체로 형성되도록 한 구성이 가장 두드러진 특징이다.Referring to this in more detail with reference to the accompanying drawings, the present invention as shown in Figure 1 is the valve hole (4) is in communication with the inlet hole (2) and the outlet hole (3) of the intake manifold (1) The configuration which is formed integrally is the most outstanding feature.

통상 주물에 의해서 제작되는 인테이크 매니폴드(1)를 제작시 밸브 홀(4)이 동시에 형성되도록 하되 상기 밸브 홀(4)의 상부 일측면으로는 외부와 연통될 수 있도록 하는 진공 홀(5)을 천공하고, 밸브 홀(4) 상단부 내주면으로는 나사가 형성되도록 한다.When manufacturing the intake manifold 1, which is usually manufactured by casting, the valve hole 4 is formed at the same time, but the upper side of the valve hole 4 allows the vacuum hole 5 to communicate with the outside. Perforations and screws are formed in the inner peripheral surface of the upper end of the valve hole (4).

상기와 같이 형성된 밸브 홀(4)내에는 밸브 로드(6)와 리턴 스프링(7)이 삽입되도록 한 후 상단부에서 테이퍼 플러그(8)로 나사체결시켜 밀폐되도록 한다.The valve rod 6 and the return spring 7 are inserted into the valve hole 4 formed as described above, and then screwed with the tapered plug 8 at the upper end to be sealed.

또한 밸브 홀(4) 일측으로 천공시킨 진공 홀(5) 단부에는 진공 호스와의 연결을 위해 니플(9)이 압입되도록 한다.In addition, the nipple 9 is press-fitted to the end of the vacuum hole 5 drilled to one side of the valve hole 4 for connection with a vacuum hose.

한편 상기의 진공 홀(4)은 도 2에서와 같이 테이퍼 플러그(8)에 편심되게 형성시켜 그 단부로 니플(9)을 압입시켜 형성되도록 하는 것도 가능하다.Meanwhile, the vacuum hole 4 may be eccentrically formed in the tapered plug 8 as shown in FIG. 2 so as to press-fit the nipple 9 to the end thereof.

상기한 구조에 따라 인렛 홀(2)을 통해 유입되는 배기가스는 밸브 홀(4)내에서 리턴 스프링(7)을 압축시키면서 밸브 로드(6)를 상승시키게 되면 유도된 배기가스는 아웃렛 홀(3)을 통해서 인테이크 매니폴드(1)의 흡기 통로로 공급이 된다.According to the above structure, when the exhaust gas flowing through the inlet hole 2 raises the valve rod 6 while compressing the return spring 7 in the valve hole 4, the induced exhaust gas is the outlet hole 3. ) Is supplied to the intake passage of the intake manifold (1).

이같은 밸브 로드(6)의 작동은 니플(9)과 진공 홀(5)을 통해 유도되는 엔진 부압에 의해서 작동이 되며, 다시 부압이 작용하지 않게 되면 리턴 스프링(7)에 의해서 밸브 로드(6)가 하강하면서 헤드(6A)가 인렛 홀(2)측 단부를 폐쇄시키게 되어 더이상 인테이크 매니폴드(1)측 흡기 통로로의 배기가스 도입을 중단시키게 된다.The operation of the valve rod 6 is operated by the engine negative pressure induced through the nipple 9 and the vacuum hole 5, and when the negative pressure is not applied again, the valve rod 6 is operated by the return spring 7. As the head is lowered, the head 6A closes the inlet hole 2 side end to stop the introduction of exhaust gas into the intake manifold 1 side intake passage.

따라서 인테이크 매니폴드(1)내에서의 배기가스는 더이상 외부로 누출될 염려가 없어지게 되고, 내부로 장착되므로 엔진 룸내 미관 개선및 다른 인접한 부품과의 간섭이 없어지게 된다.Therefore, the exhaust gas in the intake manifold 1 is no longer leaked to the outside, and is mounted inside so that the aesthetic improvement in the engine room and the interference with other adjacent parts are eliminated.

특히 본 고안은 인테이크 매니폴드(1)의 주물 제작시 동시에 형성되고, 단순히 몇가지 부품만 삽입및 체결시키기만 하면 되므로 장착이 대단히 간편해지면서 원가가 대폭 절감되는 영구적인 사용이 가능한 효과를 제공하게 되는 것이다.In particular, the present invention is formed at the same time when the casting of the intake manifold (1) is formed, and only a few parts are inserted and fastened, so that the installation is very simple and the cost is greatly reduced, thereby providing a permanent use effect. .
