Abstract

본 발명은 와류 흡기방식에 의한 다 실린더용 흡기 매니폴드에 관한 것으로, 특히 흡기의 유속을 증가시킴과 동시에 와류를 형성하여 연료와 공기의 혼합효율을 증가시킴은 물론, 혼합기의 완전연소화를 촉진하여 연소실내의 카본층 형성과 배출 유해가스의 저감을 실현하고자, 흡기 매니폴드(11) 및 흡기 매니폴드(11)의 단면을 벤츄리관의 형상으로 구성하여 흡입공기의 유속을 증가시킬 수 있도록 하고, 실린더 헤드의 흡기포트에 접하는 부분의 흡기 매니폴드(11)의 출구측 관내 중앙에 삼각형의 안내깃(12)을 설치하여 실린더의 연소실내에 흡입되는 공기와 연료의 혼합기가 와류를 형성하도록 구성된 것인 바, 흡기 매니폴드(11)내의 관을 흐르는 공기의 압력과 유속이 변화되어 정상적인 층류의 상태로 매니폴드의 관내를 흐르고, 흡입공기가 삼각형태의 안내깃(12)에 의해 와류를 형성하면서 실린더의 연소실로 흡입되어, 인젝터를 통해 연소실에 분사되는 연료가 와류를 형성하는 공기와 균일하게 혼합되면서 폭발하여 연소 사이클을 형성하도록 된 것이다.The present invention relates to a multi-cylinder intake manifold by the vortex intake method, and in particular, to increase the flow rate of the intake and at the same time to form a vortex to increase the mixing efficiency of fuel and air, as well as to promote the complete combustion of the mixer In order to realize the formation of a carbon layer in the combustion chamber and the reduction of the exhaust harmful gas, the cross section of the intake manifold 11 and the intake manifold 11 is formed in the shape of a venturi tube to increase the flow rate of the intake air. And a triangular guide vane 12 in the center of the outlet side of the intake manifold 11 at the portion in contact with the intake port of the cylinder head, so that a mixture of air and fuel sucked into the combustion chamber of the cylinder forms a vortex. Bar pressure and flow rate of the air flowing through the tube in the intake manifold 11 is changed to flow in the tube of the manifold in a state of normal laminar flow, and the intake air is triangulated And by a guide vane (12) forming a vortex is drawn into the combustion chamber of the cylinder, to which the fuel injected into the combustion chamber through the injector to explode as uniformly mixed with the air to form a vortex to form a combustion cycle.
