摘要： 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.

摘要： A rotary ring has a seal end face located at an end of the axial line direction thereof perpendicularly to the axial line and an anti-seal end face located at the other end thereof in the axial line direction, wherein the seal end face and the seal end face of a fixed ring slide each other through a subject to be sealed. The cross-sectional shape of the rotary ring is made asymmetric with respect to right and left by forming a step around the outer peripheral portion thereof so that the center of gravity of the rotary ring is located at a position nearer to the anti-seal end face than the center of the plate thickness thereof. With this arrangement, the convex deformation made to the seal end face by the deformation of the rotary ring due to heat is canceled by the concave deformation made to the seal end face by a large amount of centrifugal force acting on the anti-seal end face. Accordingly, the rotary ring exhibits a stable sealing property.
