본 고안은 흡기매니폴드(Intake manifold) 플랜지의 벤트(VENT)구조에 관한 것으로, 특히 이물질이 흡기매니홀드 플랜지를 통하여 엔진내부로의 유입을 방지하여 엔진성능의 안정화를 이룰수 있는 흡기매니폴드 플랜지의 벤트구조에 관한 것이다.The present invention relates to a vent structure of an intake manifold flange. Particularly, an intake manifold flange of the intake manifold flange can prevent stabilization of engine performance by preventing foreign substances from entering the engine through the intake manifold flange. It relates to a vent structure.

일반적으로 흡기매니폴드는 기화기의 혼합실 출구와 각 실린더의 흡기구멍을 연결하여 기화기에서 만들어진 무화혼합가스를 각 실린더에 배분하는 주철제 분기관이다.Generally, the intake manifold is a cast iron branch pipe that distributes atomized mixed gas produced in the vaporizer to each cylinder by connecting the outlet of the vaporizer chamber and the intake hole of each cylinder.

다기통엔진에서는 인접하는 실린더의 흡기구멍을 2개씩 공통으로 갖는 것이 보통이며, 기화기와 각 실린더 흡기구멍사이의 관내 길이는 되도록 같은 것이 좋으며, 관의 내경은 클수록 흡입효율이 높아지게 된다.In a multi-cylinder engine, it is common to have two intake holes of adjacent cylinders in common, and the same length as the pipe length between the vaporizer and each cylinder intake hole is good.

이러한 흡기매니폴드의 설치는, 실린더헤더의 각 연소실부위에 주위보다 돌출되게 흡기매니폴드장착용 플랜지면이 마련되어 있고 상기 플랜지면상에 플라스틱 흡기매니폴드 플랜지를 설치하여 실린더헤드의 연소실과 흡기매니홀드를 서로 연결시키게 된다.The intake manifold is provided with an intake manifold mounting flange surface protruding from the surroundings of each cylinder chamber of the cylinder header, and a plastic intake manifold flange is provided on the flange surface to connect the combustion chamber and the intake manifold of the cylinder head. Are connected to each other.

도 2 및 도 3를 참조하면, 흡기매니폴드 플랜지(10)상에는 주위보다 두께가 얇은 다수의 홈부(12)가 마련되어 있고, 상기 홈부(12)와 인접되게 챔버(14)가 형성되어 있다. 또한, 상기 홈부(12)와 이와 연접하는 상기 챔버(14)에는 하부 즉 두께방향으로 이물질이 유출될 수 있도록 이물질 제거용홀(16)이 형성되어 있다.2 and 3, on the intake manifold flange 10, a plurality of grooves 12 having a thickness thinner than the surroundings are provided, and a chamber 14 is formed adjacent to the grooves 12. In addition, the foreign material removal hole 16 is formed in the chamber 14 which is in contact with the groove portion 12 so that foreign matter can flow out of the lower portion, that is, in the thickness direction.

따라서 차량운행중 흡기매니폴드 플랜지(10)부에 외부에서 유입되는 물과 기름등의 이물질이 상기 홈부(12)와 챔버(14)에 형성된 이물질 제거용홀(16)을 통하여 용이하게 외부로 배출시킬 수 있다. 이러한 홀의 형성은 플랜지하면에서 핀을 사용해 플라스틱 흡기매니폴드 사출시 형성하게 된다.Therefore, foreign matters such as water and oil introduced from the outside into the intake manifold flange 10 during vehicle operation can be easily discharged to the outside through the foreign material removal hole 16 formed in the groove part 12 and the chamber 14. have. These holes are formed by injecting plastic intake manifolds using pins at the bottom of the flange.

도 4는 실린더헤드의 흡기매니폴드 장착용 플랜지면을 도시하는 것으로, 도면에 도시된 바와 같이 실린더헤드(18)면으로 부터 돌출되게 형성되어 있고 고정볼트 장착용 다수의 볼트구멍(24)이 형성되어 있다.4 shows a flange face for mounting the intake manifold of the cylinder head, which is formed to protrude from the face of the cylinder head 18 as shown in the drawing, and a plurality of bolt holes 24 for fixing bolt mounting are formed. It is.

따라서 상기 흡기매니폴드 플랜지(10)를 실린더헤드(18)의 흡기매니폴드 장착용 플랜지(20)면에 가스킷을 설치한 상태에서 양자의 포트구멍을 일치시켜 고정볼트를 사용하여 서로 고정하여 흡기매니폴드와 연소실의 흡기포트를 서로 연결하게 된다.Therefore, while the gasket is installed on the surface of the intake manifold mounting flange 20 of the cylinder head 18, the inlet manifold flange 10 is matched with both port holes to be fixed to each other using a fixing bolt. The fold and the intake port of the combustion chamber are connected to each other.

이상에서와 같은 본 고안에 따른 플라스틱 흡기매니폴드의 플랜지부 벤트구조에 의하면, 차량의 운행중 흡기매니폴드 플랜지로 유입되는 물과 기름등의 이물질을 이물질 제거용홀을 통하여 용이하게 제거할 수 있어 엔진 연소실내부로의 이물질 침입을 방지할 수 있는 효과가 있다.According to the flange portion vent structure of the plastic intake manifold according to the present invention as described above, the foreign matter, such as water and oil flowing into the intake manifold flange during the operation of the vehicle can be easily removed through the hole for removing foreign substances engine combustion chamber There is an effect that can prevent the entry of foreign matter into the interior.
