ABSTRACT:
An electronic fuel injection system for an internal combustion engine comprising an electronic control system having a central processing unit for detecting engine speed, throttle setting regulating air supply to the engine, exhaust gas concentrations, and for controlling fuel injection. The central processing unit also calculates an open basic injection time, corrected by sensors for engine cooling water and air supply temperature and a closed-loop injection time using an exhaust gas sensor.
