본 발명은 흡기매니폴드의 가변 노우즈 장치에 관한 것으로, 더욱 상세하게 는 흡기매니폴드의 노우즈부 크기를 저속과 중속, 고속의 성능에 대한 전체적인 경향을 보면서, 적당한 속도가 발생되도록 노우즈부의 면적 크기를 결정할 수 있게 되는 흡기매니폴드의 가변 노우즈 장치에 관한 것이다.The present invention relates to a variable nose device of an intake manifold. More specifically, the size of the nose portion of the intake manifold is measured while the overall size of the nose portion of the intake manifold is considered to be low speed, medium speed, and high speed performance. The variable nose device of the intake manifold can be determined.

V6 엔진의 성능을 향상시키는 인자들 중 가장 많은 영향을 주는 인자로는 흡기매니폴드가 있다. 상기 흡기매니폴드는 에어크리너와 쓰로틀바디를 통해 유입된 공기를 각 실린더로 보내기 위해 만들어진 장치이다.The most influential factor that improves the performance of the V6 engine is the intake manifold. The intake manifold is a device made to send the air introduced through the air cleaner and the throttle body to each cylinder.

도 1은 종래 기술에 따른 흡기매니폴드를 도시한 도면이고, 도 2는 도 1의 A부를 도시한 측단면도이다.1 is a view showing an intake manifold according to the prior art, Figure 2 is a side cross-sectional view showing part A of FIG.

상기한 흡기매니폴드(2)는 엔진 성능에 큰 영향을 주는데, 특히 쓰로틀바디 후단의 노우즈부(4)의 형상은 그 엔진의 전체적인 성능 경향을 결정하는 중요한 인자로 작용된다. 그리고 흡기매니폴드(2)는 입구부분에 형성된 노우즈부(4)를 절단. 확대한 것으로 중심부분에 짚튜브(Zip Tube)(6)를 가지고 있으며 그 상하부분에 측벽이 확장된 부분이 노우즈부(4)가 되는 것이다. The intake manifold 2 has a great influence on the engine performance. In particular, the shape of the nose portion 4 at the rear end of the throttle body serves as an important factor in determining the overall performance tendency of the engine. And the intake manifold 2 cuts the nose part 4 formed in the inlet part. The enlarged portion has a zip tube (6) in the center portion, and a portion in which the side wall is extended at the upper and lower portions thereof becomes the nose portion (4).

상기 흡기매니폴드(2)의 입구부분인 노우즈부(4))의 개구부분이 작을 경우, 저속 성능에서는 탁월한 효과를 보여주나 중속 및 고속에서는 공기 유입량이 작아져서 성능의 저하를 발생하게 된다.When the opening portion of the nose portion 4, which is the inlet portion of the intake manifold 2, is small, an excellent effect is exhibited at low speed performance, but air inflow is small at medium speed and high speed, resulting in a decrease in performance.

반대로, 노우즈부(4)를 크게 할 경우 고속에서는 공기의 유입량이 크게 되고 또한 상하 압력파의 간섭이 회피되어 높은 성능을 가지는 엔진이 되지만, 저속에서는 충분한 층상 흐름이 생성되지 않아 오히려 성능 저하를 유발하게 되는 문제점이 있었다. On the contrary, when the nose part 4 is made large, the inflow of air is high at high speeds, and the interference of up and down pressure waves is avoided, and the engine has high performance, but at low speeds, sufficient laminar flow is not generated, causing performance deterioration. There was a problem.

상기한 바와 같이 이루어지는 종래기술의 문제점을 해소하기 위하여 제안된 것으로 본 발명의 목적은 흡기매니폴드의 노우즈부 크기를 저속과 중속, 고속의 성능에 대한 전체적인 경향을 보면서, 적당한 속도가 발생되도록 노우즈부의 면적 크기를 결정할 수 있게 되는 흡기매니폴드의 가변 노우즈 장치를 제공한다.The object of the present invention has been proposed to solve the problems of the prior art made as described above, while the overall size of the nose portion of the intake manifold is observed while watching the overall tendency for the performance of low speed, medium speed, and high speed, so that a proper speed is generated. Provided is a variable nose device of an intake manifold capable of determining an area size.
