  • Electronic concentration control system
    Patent number: 5697214
    Abstract: An electronic concentration control system in which a first exhaust gas composition sensor located in an exhaust pipe downstream from a catalytic converter is connected to an input to a P.I. circuit which generates a control output signal comprising a succession of opposing triangular ramps. The system includes a second exhaust gas composition sensor located in the exhaust pipe upstream from the catalytic converter generating a signal which is fed to a proportional integral circuit whose integrating and multiplying coefficients are altered on the basis of the control signal. The system includes a diagnostic circuit which checks the efficiency of the first and second sensors.
    Type: Grant
