Abstract:
A fuel control system for an engine system including a fuel supply and a combustion chamber, the system comprising:at least one fuel injector with a calibrated nozzle to direct a fuel flow from a fuel supply into a combustion chamber of an engine, the calibrated nozzle having a known fuel flow vs. pressure drop characteristic;a servo valve connected between the fuel supply and the calibrated nozzle to meter the fuel flow from the fuel supply to the calibrated nozzle;a pressure transducer operably associated with the at least one calibrated nozzle to measure a pressure drop in the fuel flow across the calibrated nozzle; anda controller operably associated with the pressure transducer and the servo valve to control the metering of the fuel flow by the servo valve based on the pressure drop measured by the pressure transducer and the known fuel flow vs. pressure drop characteristic of the calibrated nozzle.
