ABSTRACT:
A method to control the output of a turbine engine pulses individual fuel injectors completely on and then completely off in selectable groups rather than in unison. The operation of the groups are staggered in time to minimize the periods of no fuel flow to the engine. Simplicity in the control of individual injectors is achieved by electrically controlling individual injectors rather than mechanically controlling the fuel supplied to all injectors, and, in addition, offers the advantage of minimizing the periods of no fuel flow to maintain combustion stability at low loads. Electrically controlling injectors positioned at the point of fuel usage improves upon fuel atomization and eliminates the problem of unequal distribution of fuel from multiple injection points connected to a common fuel metering system.
