DRIVE
May 27, 2026
A fuel injector for a turbine engine includes a fuel scheduling valve configured for regulation of fuel flow from a fuel inlet (115), in response to fuel pressure received at the fuel inlet. Primary, secondary and auxiliary fuel circuits (117, 119, 118) receive fuel from the scheduling valve, and an electrically-controlled valve (120) is provided in fluid communication with the auxiliary circuit (118), which electrically-controlled valve (120) is adapted and configured to actively control fuel through the auxiliary circuit (118) in response to a control signal.
