Abstract

자동차의 흡기 장치를 통과한 공기 및 연료의 흡입량을 향상시키기 위하여 흡기와 배기 사이에 오버랩 구간을 설정할 때 너무 크게 설정하면 연소실(53)로 유입된 혼합기가 역류하거나 흡기 유동이 방해되어 역 효과를발생시킴으로써 엔진 출력이 저하됨을 방지하기 위하여, 흡기 매니폴드(55)의 출구 부분에서 역류되는 혼합기를 감지하여 서지 탱크(56)로 유입되는 공기를 차단함으로써 혼합기의 역류를 차단하게 되는 역류 방지 수단을 포함하여 구성함으로써 엔진 출력을 향상시킬 수 있게 된다.To set an overlap section between intake and exhaust in order to improve the intake amount of air and fuel passing through the intake device of the vehicle, if it is set too large, the mixer introduced into the combustion chamber 53 flows backward or obstructs the intake flow, thereby causing adverse effects. In order to prevent the engine output from being lowered, it includes a backflow preventing means for detecting the backflow of the mixer in the outlet portion of the intake manifold 55 and blocking the backflow of the mixer by blocking the air flowing into the surge tank 56. In this way, the engine power can be improved.
