Abstract
본 발명은 람다 피드백 컨트롤에 의한 세컨드리 에어량 제어장치에 관한 것으로, 특히 배기관에 설치한 산소센서와, 산소센서 부근의 배기관으로 에어크리너를 통한 2차공기를 제공받는 공기주입관과, 상기 산소센서의 레벨로 감다(F/A)를 판단하여 2차공기량을 제어토록 프로그램된 제어유니트로 구성하여 람다가 리치일 경우 세컨드라이 에어의 공기량을 증대시켜 촉매의 산화반응을 촉진시켜 오염물질인 HC,CO의 량을 감소시키기로, 반대로 감다가 라인일 경우 공기량을 줄여 NOx의 생성을 억제시켜줌으로써 배기가스로 인한 대기오염을 방지토록함을 특징으로 하는 람다 피드백 컨트롤에 의한 세컨드라이 에어량 제어장치에 관한 것이다.The present invention relates to a secondary air amount control device by lambda feedback control, and in particular, an oxygen sensor installed in the exhaust pipe, an air injection pipe receiving secondary air through the air cleaner to the exhaust pipe near the oxygen sensor, and the oxygen sensor The secondary air volume is configured as a control unit that is programmed to control the F / A by determining the level of F / A. The second air volume control device by lambda feedback control to reduce the amount of CO, to prevent the air pollution caused by the exhaust gas by reducing the amount of air in the case of the line, while reducing the amount of air in the case of the line .
