Abstract

본 발명은 자동차 엔지의 공연비 제어장치에 관한 것으로서, 연소후 실린더로 부터 배출되는 배기가스에 포함된 산소의 농도를 검출하는 산소센서를 각 실린더의 배기 매니폴드에 설치하여 이에 검출되는 정보가 ECU를 통해 해당 실린더에 연료를 분사하는 연료 인젝터를 독립적으로 제어 할수 있도록 함으로써, 각 실린더마다 유입되는 흡입 공기량에 따라 연료 분사량을 제어토록하여 정밀한 고연비로 출력, 연비, 배기 및 운전성을 향상시킬 수 있도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-fuel ratio control apparatus for an automobile engine, wherein an oxygen sensor for detecting the concentration of oxygen contained in exhaust gas discharged from a cylinder after combustion is installed in an exhaust manifold of each cylinder so that information detected therefrom By controlling fuel injectors that inject fuel into the cylinders independently, the fuel injection amount can be controlled according to the amount of intake air flowed into each cylinder to improve output, fuel efficiency, exhaust and operability with high fuel efficiency. will be.
