Turbine engine pulsed fuel injection utilizing stagger injector operation

A method for controlling the injection of fuel in pulses by selectable groups of injectors in a turbine engine having a engine shaft and a combustion chamber and having at least four fuel injectors arranged in groups and at least one sensor for sensing operating signals from said engine, said method comprising the steps of:

• a) sensing at least one operating sensor signal from said turbine engine using said sensor;
• b) receiving and comparing with a programmable electronic control unit the value for said sensor signals from said turbine engine to the value of a desired signal and generating with said electronic control unit fuel injector control signals to said selected groups of injectors in response thereto;
• c) directing said fuel injector signals to said selected groups of fuel injectors to modify the pulse duration and/or frequency of fuel injection of said groups independently from each other in response to a deviation from desired engine operating parameters caused by variable operating loads encountered by said turbine engine;
• and
• c) delivering fuel in pulses to said combustion chamber using said selected groups of fuel injectors.
