Description
본 발명은 차량 엔진의 흡기포트 구조에 관한 것으로서, 상세하게는 엔진의 연소실로 흡기시 흡기포트에서 발생되는 맥동의 발생을 감소시킬 수 있도록 형성한 차량 엔진의 흡기포트 구조에 관한 것이다.The present invention relates to an intake port structure of a vehicle engine, and more particularly, to an intake port structure of a vehicle engine formed so as to reduce the occurrence of pulsation generated at the intake port during intake into the combustion chamber of the engine.
일반적으로 차량의 엔진에서 흡배기장치는 도 1에 도시한 바와 같이 에어클리너(11) 및 서지탱크(12)를 통과한 흡기가 흡기매니폴드(13)를 거쳐 엔진의 실린더헤드(14)에 형성된 통로인 흡기포트(15: Intake Port)로 분배되어 연소실(16)로 유입된 후, 배기포트(17)와 배기매니폴드(18)를 통해 배기가스가 배출되도록 되어있다.In general, the intake and exhaust device of the engine of the vehicle is a passage formed in the cylinder head 14 of the engine via the intake manifold 13, the intake air passing through the air cleaner 11 and the surge tank 12 as shown in FIG. After being distributed to the intake port 15 (Intake Port) and introduced into the combustion chamber 16, the exhaust gas is discharged through the exhaust port 17 and the exhaust manifold 18.
도 2는 본 발명의 적용부를 보다 구체적으로 나타낸 사시도로서, 서지탱크(12)로부터 흡기매니폴드(13)가 연결되고, 이러한 흡기매니폴드(13)가 실린더헤드(14)의 흡기포트(15) 입구로 연결되는 상태를 나타낸 것이다.2 is a perspective view showing the application of the present invention in more detail, in which the intake manifold 13 is connected from the surge tank 12, the intake manifold 13 is the intake port 15 of the cylinder head 14 It shows the state connected to the inlet.
도 5는 종래 흡기포트 부위의 구조를 나타낸 단면예시도로서, 실린더헤드(14)에 장착된 흡기매니폴드(13)로 분배된 흡기가 흡기포트(15)를 통하여 각 연소실(16)로 유도되는 것을 나타내었다.5 is a cross-sectional view illustrating a structure of a conventional intake port portion, in which intake air distributed to an intake manifold 13 mounted on a cylinder head 14 is guided to each combustion chamber 16 through an intake port 15. It was shown.
그러나 상기와 같은 종래의 흡기포트 구조에서는 연소실로 흡입되는 혼합기나 공기가 관성에 따라 흡기관내를 일정한 상태로 흐르려고 하지만, 흡기밸브가 열리는 것은 흡기행정 뿐이므로 흐름이 막혔다가 흐르게 되는 움직임을 하게 되는 맥동이 발생되는 바, 엔진의 RPM 변화에 따른 흡입공기의 관성력과 상기한 바와 같이 흡기밸브의 개폐에 의한 맥동이 발생된다. 이에 따라 2차 흡기시에 정체(Delay)현상이 발생되며 흡입효율이 떨어지게 되는 문제점이 있었다.However, in the conventional intake port structure as described above, the mixer or air sucked into the combustion chamber tries to flow in the intake pipe in a constant state according to the inertia. However, the intake valve is opened only because the intake stroke is opened. Pulsation is generated, the inertia force of the intake air according to the RPM change of the engine and the pulsation by opening and closing of the intake valve as described above. Accordingly, there is a problem in that delay occurs during the second intake and the suction efficiency decreases.
본 발명은 이러한 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은 실린더헤드의 흡기포트로 유입되는 공기의 진행을 원활히 유지시켜 맥동을 감소시키도록 하며, 흡기의 충진효율을 향상시키도록 하는 차량 엔진의 흡기포트 구조를 제공하는 데 있다.The present invention has been made in view of the above problems, an object of the present invention to smoothly maintain the progress of the air flowing into the intake port of the cylinder head to reduce the pulsation, and to improve the filling efficiency of the intake engine It is to provide an intake port structure of.
