<p>A fuel/air metering system with an air throttle valve and fuel valve positively linked with the flow cross-sectional area of each valve proportional to the other. The air pressure drop across the air throttle valve is sensed and a corresponding fuel pressure drop is computed. A servo valve in series with the fuel valve is controlled so that the pressure drop across the fuel valve corresponds to this computed value.</p> |
