Abstract

As the step to improve fuel efficiency, there is the system to build up the eddy of combustion chamber at the suction line in order to increase the combustion efficiency. The models installed with no vortex generation system or with various shapes of the system are examined by fluid analysis. Vortex generation system is installed prior to the suction of combustion chamber. The wing of this system winds itself around the suction air and generates the vortex. This study investigates the flow of suction air and the pressure distribution of suction stroke by using the eddy generation system.

자동차의 연비개선을 위한 대책으로 연소 효율 증대를 위해서 흡입라인에 연소실의 와류를 형성시켜주는 장치를 모델링하였다. 와류발생장치가 장착되지 않은 것과 와류발생장치의 형태가 다른 모델들을 각각 장착하여 유동해석을 실시한다. 와류발생장치는 공기의 연소실 흡입 전에 설치되어 와류발생장치의 날개에 의해 흡입공기를 휘감으며 와류를 발생시키게 된다. 본 연구에서는 와류발생장치를 사용함으로써 흡입 공기의 유동과 흡입행정의 압력분포를 해석하여 와류발생장치의 효과를 조사할 수 있다.
