The present invention relates to an intake quantity control device included in an intake manifold, and an operating method thereof. The present invention includes: an intake manifold inducing air into each combustion chamber; a surge tank installed at the front end of the intake manifold to prevent intake pulsation; and an intake quantity control device installed in the intake manifold to control an air volume flowing from the surge tank to each runner formed in the intake manifold. The intake quantity control device includes: a control valve blocking a runner by being expanded from the inner surface of the runner to the longitudinal center of the runner, or being contracted from the longitudinal center of the runner to the inner surface of the runner. As an aperture opening structure, included in a camera lens, is applied to two ports (tangential port, helical port), formed in a cylinder head of the intake manifold, and then the ports are opened in different sizes, the present invention is capable of controlling the amount of fresh air, supplied to the combustion chamber through each of the ports, in accordance with combustion conditions such as emission reduction, the improvement of fuel efficiency, and high-speed driving. 본 발명은 흡기 다기관에 구비된 흡기량 제어장치 및 그 작동방법에 관한 것으로, 각각의 연소실로 공기를 유도하는 흡기 다기관과, 흡기 맥동이 발생되지 않도록 흡기 다기관 전단에 구비된 써지 탱크 및, 써지 탱크로부터 흡기 다기관에 형성된 각각의 러너를 향해 유입되는 공기량을 제어하도록 흡기 다기관에 장착된 흡기량 제어장치를 포함하며, 흡기량 제어장치는, 러너의 내측면에서 러너의 길이방향 중심을 향해 확장됨으로써 러너를 막거나, 러너의 길이방향 중심에서 러너의 내측면을 향해 수축됨으로써 러너를 여는 조절 밸브를 포함하며, 카메라 렌즈에 구비되는 조리개 개폐 구조를 흡기 다기관에서 실린더 헤드에 형성된 2개의 포트(탄젠셀 포트, 헬리컬 포트)에 적용하고 각기 다른 크기로 개구함으로써, 에미션 저감, 연비 향상 또는 고속 주행 등의 연소조건에 따라 각각의 포트를 통해 연소실로 공급되는 신기의 양이 조절될 수 있는 효과가 있는 본 발명은 흡기 다기관에 구비된 흡기량 제어장치 및 그 작동방법을 제공한다.
