ABSTRACT:
A fuel system for a gas turbine engine is arranged to schedule fuel flow between primary and secondary fuel injectors in order to obtain good ignition and light round when the engine is operating on diesel fuel. The system includes either two solenoid valves in parallel with flow restrictors or a single solenoid operated valve and two flow restrictors. The two valves or the diverter valve schedule the fuel flow so that at engine start up, the flow to the primary and secondary fuel injectors is according to requirement proportioned. At a certain engine speed the flow to the secondary fuel injectors is reduced to purge flow and the major part of the fuel flow passes to the primary fuel injectors.
