摘要

PROBLEM TO BE SOLVED: To provide a fuel flow controller capable of dealing with a change in flow characteristics of a valve.SOLUTION: A fuel flow controller comprises: a flow estimation unit acquiring pressures before and after a nozzle provided downstream of a fuel flow regulating valve from a state quantity of fuel flowing in a fuel system in which the fuel flow regulating valve is provided, and estimating a flow volume of the fuel flowing in the nozzle on the basis of the acquired pressures; and a valve degree-of-opening adjustment unit adjusting a degree of opening of the fuel flow regulating valve on the basis of an estimation result of the flow estimation unit.SELECTED DRAWING: Figure 2
