ABSTRACT:
A fuel admission valve for metering gas without using a mass flow sensor. The valve uses a flow control element and nozzle, an actuator, a fuel supply pressure sensor, a fuel supply temperature sensor, a flow control element position sensor, and a flow control circuit to meter gas in sonic flow with insensitivity to the discharge pressure.
