  • Fuel combustion control system
    Patent number: 4545009
    Abstract: Estimated fuel flow rate is calculated by reading first data of the relationship between the opening degree of a fuel control valve and a fuel flow rate. Then, a compensation coefficient is calculated based on the estimated fuel flow rate, and the actual fuel flow rate is controlled on the basis of the compensation coefficient. Estimated excess air ratio is calculated by reading second data representing the relationship between the opening rate of an air control damper and the air flow rate. Then, the actual fuel flow rate and the air flow rate are controlled depending on the predetermined relationship of values between the estimated excess air ratio and the desired excess air ratio.
