PURPOSE:To obtain a small sized and high reliable equipment whose fuel injector is easily manufactured, by feeding liquid fuel of super fine flow rate to a fuel injector containing a check valve through a high pressure constant flow rate pump, mixing the fuel with an inert gas and spouting it in the form of mist from an exhaust nozzle of the injector. CONSTITUTION:By using a high pressure constant flow rate pump 21, liquid fuel such as benzen with a super fine flow rate is supplied to an fuel injector 24 involving the structure of a check valve 25. Thereinto an inert gas having compressibility such as nitrogen gas is blown, and is mixed in the injector 24. Then the abovementioned liquid fuel is spouted in the form of mist from an exhaust nozzle 27 of the injector 24. Thereby exact control of fuel of super fine flow rate is enabled without the influence of change of combusion pressure, so that the diameter of the exhaust nozzle of the fuel injector can be made large, and the unstable combusion does not occur in the case of low difference pressure. Thus the injector dose not suffer from thermal damage. Further, the timing adjustment for feeding oxdizing agent can be facilitated by making the rise time of feeding fuel short. |
