FUEL FLOW CONTROL DEVICE FOR STIRLING ENGINE

PURPOSE:To realize a normally excellent combustion state in a wide range of calorific values, by a method wherein a fuel nozzle is provided with a moving part and a stationary part, a flow rate of fuel is controlled and a fuel injection velocity is also controlled by varying a fuel injection sectional area through the drive of the moving part. CONSTITUTION:A title control device is provided with a moving part 12 mounted in a pipe 11 through which gas fuel passes, an elongated slitlike injection hole 12a, and a device, for example, a pulse motor 10, driving the moving part 12. A plurality of slits 12a are circumferentially formed at intervals of a given distance. The moving part 12 is driven with the aid of a pulse motor 10 for vertical movement to change an injection length of the slitlike injection hole 12a, i.e. fuel injection sectional area. Thus, a flow rate of fuel injected in a combustion space is controlled. Since a flow rate of fuel injected in the combustion space is also controlled, a fuel injection velocity can be also controlled along with control of a flow rate of fuel, and a normally excellent combustion state can be realized in a wide range of calorific values.
