ABSTRACT:
An air-fuel ratio control system for an automobile engine of a type having a fuel injection system wherein at least two of parameters including the engine speed, the opening of a throttle valve and the negative pressure developed inside a fuel intake passage are utilized to detect the rate of flow of incoming air to be mixed with an injected mist of fuel to form a combustible mixture. The amount of fuel to be injected into the intake passage depends on the detected rate of flow of the incoming air. A composition sensor for detecting the concentration of an exhaust gas component is also provided for controlling an EGR control valve for controlling the recirculation of a portion of exhaust gases from an exhaust passage into the intake passage.
