Abstract

보조 공기 공급계에 역류하여 체류하는 연료에 의하여, 공연비가 변동하고, 따라서, 배기성능이 악화하는 것을 방지한다.By the fuel which flows back in the auxiliary air supply system, the air-fuel ratio fluctuates, thereby preventing the exhaust performance from deteriorating.

보조 공기 공급로(7)를 통해 스로틀밸브 상류측으로부터 유도되는 보조 공기가 보조 공기용 어댑터(5)의 외주와 홀더(2)내주로 형성되는 링상의 보조 공기 도입 중공부(6)내로 도입된다. 그리고, 상기 보조 공기 도입 중공부(6)로부터 보조 공기 분공을 통해 보조 공기를 분출시킨다. 여기서, 상기 보조 공기 도입 중공부(6)에 보조 공기 공급경로를 회피하여 스페이서부재(8)를 사이에 끼워넣음으로써 보조 공기 도입 중공부(6)의 공간용적을 보조 공기 공급로(7)축으로 기울여서, 역류연료가 체류하는 공간용적을 감소시키고 있다.Auxiliary air guided from the upstream side of the throttle valve through the auxiliary air supply passage 7 is introduced into the ring-shaped auxiliary air introduction hollow 6 formed around the outer periphery of the adapter 5 for auxiliary air and the holder 2. . Then, the auxiliary air is ejected from the auxiliary air introducing hollow part 6 through the auxiliary air hole. Here, the space volume of the auxiliary air introduction hollow portion 6 is reduced to the auxiliary air supply passage 7 by sandwiching the spacer member 8 between the auxiliary air introduction hollow portion 6 and avoiding the auxiliary air supply path. Tilt to reduce the volume of space in which reflux fuel resides.
