Abstract

본 발명의 목적은 연소실로 유입되는 혼합기가 강력한 텀블을 일으킬 수 있도록 텀블포트를 제공하면서 흡기포트의 스로트부의 단차발생도 해결할 수 있는 엔진의 흡기 포트구조를 제공하는데 있다.An object of the present invention is to provide an intake port structure of the engine that can solve the step generation of the throat portion of the intake port while providing a tumble port so that the mixer flowing into the combustion chamber can cause a strong tumble.

이를 실현하기 위한 본 발명은 실린더헤드의 연소실 측에 밸브시이트가 삽이되는 부위의 상측에 형성되는 제1스로트부에 대해 소정의 각도(B)로 형성된 유입통로부를 포함하여 이루어지는 엔진의 흡기 포트구조를 특징으로 한다.The present invention for realizing this includes an inlet port portion including an inlet passage portion formed at a predetermined angle B with respect to a first throat portion formed above the portion at which the valve seat is inserted on the combustion chamber side of the cylinder head. It is characterized by a structure.

상기한 제1스로트부는 소정의 기구에 의해서 형성되며, 혼합기 유동이 향상되도록 내측에 단수직부와 외측에 장수직부가 형성되어 이루어지는 엔진의 흡기 포트구조를 제공하는데 있다.The first throat part is formed by a predetermined mechanism, and the inlet port structure of the engine is provided with a short vertical part on the inside and a long vertical part on the outside so that the mixer flow is improved.

상기한 제1스트로부의 상측에 형성되는 제2스트로부와, 이 제2스트로부에 대해 각도 (B)보다 작은 각도(C)로 형성된 유입통로부를 포함하여 이루어지는 엔진의 흡기 포트구조를 제공하는데 있다.It is to provide an intake port structure of an engine comprising a second straw portion formed above the first straw portion and an inflow passage portion formed at an angle C smaller than the angle B with respect to the second straw portion. .

상기한 제2스트로부는 소정의 기구에 의해 형성되며, 혼합기의 유동이 향상되도록 내측에 제1수직부와, 제2수직부가 형성되어 이루어지는 엔진의 흡기 포트구조를 제공하는데 있다.The second straw portion is formed by a predetermined mechanism, and provides an intake port structure of an engine in which a first vertical portion and a second vertical portion are formed inside so that the flow of the mixer is improved.
