Claim 8:
9. The method according to claim 8 comprising the further steps of:
determining a closed-loop contribution ({dot over (m)}F_CL) of a fuel flow rate by means of the PID controller, which zeroes a difference between the objective value (λOBJ) of the air/fuel ratio and the actual value (λ) of the air/fuel ratio measured by the oxygen sensor (18, 18*, 18**);
determining a further contribution ({dot over (m)}F_ADAT) of the fuel flow rate depending on the integral action of the PID controller under stationary conditions; and
determining an objective fuel flow rate ({dot over (m)}F_OBJ) by means of a sum of the nominal fuel flow rate ({dot over (m)}FUEL_N), the closed-loop contribution ({dot over (m)}FCL) of the fuel flow rate and the further contribution ({dot over (m)}FADAT) of the fuel flow rate.
