摘要： A fuel supply method and circuit including at least one flow-rate regulating valve is provided at a return pipe for returning excess return fuel from a combustion chamber side. During the combustion operation, the fuel from the supply pipe is supplied to a fuel injection nozzle with the return pipe closed or restricted to a predetermined opening degree and the back pressure of the return pipe raised by at least one flow-rate regulating valve. The fuel is supplied to the fuel injection nozzle as being pressurized by the return back pressure, so that the fuel injection nozzle supplies to the combustion chamber the fuel that has been heated to a high-temperature. The return fuel is circulated from the return pipe directly through the supply pipe, and mixed in a sub-tank with low-temperature fuel from a fuel tank. The mixed fuel is supplied to the fuel injection nozzle.
