ABSTRACT:
A mixture control system comprises an oxygen sensor for generating a sensor signal varying linearly as a function of the oxygen concentration of exhaust emissions from an internal combustion engine when the air-fuel ratio of mixture supplied thereto is leaner than stoichiometric value. Optimum values of the sensor signal are stored in storage locations of a memory addressable as a function of detected engine operating parameters. A data processor determines the quantity of fuel to be supplied to the engine in accordance with the detected engine operating parameters, addresses the memory as a function of the detected engine operating parameters, detects a difference between the sensor signal and a signal addressed in the memory, integrates the difference and corrects the fuel quantity with the integrated value.
