ABSTRACT:
To control the quantity of fuel supplied to an I.C. engine, a sensor generates an exhaust gas component concentration signal. If the present fuel supply quantity does not exceed a reference quantity, the fuel supply is set according to engine operation parameters. If the preset quantity is greater than the reference quantity for a predetermined reference time, the fuel supply is set without regard to the signal. The reference time is changed as a function of engine temperature.
