ABSTRACT:
A closed-loop mixture control system for an internal combustion engine comprises an electronic control section and an electromechanical section comprised of the engine, an air-fuel metering system and an exhaust composition sensor. The system further comprises a first diagnosis circuit for testing the electromechanical section by application of a recurrent series of binary signals to the metering system, and second and third diagnosis for circuits for testing the function of the electronic control section by application of staircase waveform signal or a train of variable width pulses selectively to the input of the control section. The applied test signals are received by the respective diagnosis circuits to check the performance of the control loop.
