Abstract: A combustor assembly for a gas turbine engine is provided. The combustor assembly generally includes an annular dome and a liner that at least partially define a combustion chamber. The annular dome defines a plurality of circumferentially spaced fuel injection ports and a plurality of mounting assemblies are configured for receiving and supporting a plurality of fuel injector assemblies within the fuel injection ports. Each mounting assembly includes a ferrule positioned adjacent to and extending around a peripheral edge of the respective fuel injection port. A spring finger is coupled to an interior surface of the ferrule and extends toward a centerline of the fuel injection port to form a seal with the fuel injector assembly.

Abstract: An engine speed management control system for machines such as cold planers to regulate the idle engine speed as components of the machine are operated to perform functions while the engine is idling. An auto engine speed control routine may determine a combination of active functions of the components being performed and a corresponding idle engine speed to generate sufficient power and pressurized fluid flow to perform the functions. Upon detecting a change in the combination of active functions, the algorithm may change the idle engine speed as dictated by the new combination, or may wait for a specified delay period to determine whether further changes occur to the combination of active functions.
