Abstract

본 발명은 내연기관의 가변 흡기 시스템에 관한 것으로서, 흡기가 통하는 유로의 말단부를 형성하면서 흡기를 연소실로 하향 안내하는 흡기포트의 말단부 내면에 기관의 운전 조건에 따라 ECU의 제어에 의해 동작되는 유압 구동수단에 의하여 확장 및 수축되면서 흡기포트의 유로를 가변시킬 수 있는 플랙시블 튜브를 설치해서 된 내연기관의 가변 흡기 시스템을 제공함으로써, 간단한 구성으로 기관의 운전 상태에 따라 흡입 포트의 형상을 가변화하여 기관 운전 조건에 가장 적합한 흡기 유동을 유도함으로써, 기관의 출력 및 연비를 향상시키고 배기가스를 저감시켜 운전성을 향상시킬 수 있도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable intake system of an internal combustion engine, wherein a hydraulic drive operated by control of an ECU in accordance with operating conditions of an engine is performed on an inner surface of a distal end of an intake port for guiding the intake downward to the combustion chamber while forming the distal end of the flow path through which the intake air flows. By providing a variable intake system of an internal combustion engine provided with a flexible tube capable of varying the flow path of the intake port while being expanded and contracted by means, the shape of the intake port is varied according to the operating state of the engine with a simple configuration. By inducing the intake flow that is most suitable for the engine operating conditions, it is possible to improve the output and fuel efficiency of the engine and to reduce the exhaust gas to improve the operability.
