Abstract
PURPOSE: To lower a limit that prevents going-out by blowing, by mounting a by-path duct and an adjusting valve between an air discharge port and an outlet at the exhaust side of a heat exchanger.
CONSTITUTION: When an accelerator pedal 12 is rapidly opened due to quick deceleration, a signal for indicating the opening of a by-path valve 25 is put out because output N×G from a set instrument 13 reduces in stages, the by-path valve 25 is opened and by-path pipes 26a, 26b are communicated. Thus, excess air among compressed air discharged from a compressor 1 is discharged to an exhaust duct 28 through a by-path duct 26. Meanwhile, since fuel flow rate Gb computing indicated by means of a computing circuit 19 on the basis of a rapid deceleration command and air flow rate corresponding to Gb are fed to a combustor 5, a limit that prevents going-out by blowing (Gbmin) can be set lower than conventional devices.
