Abstract: A fluidic component having a flow chamber allowing a fluid flow to flow through, said fluid flow entering the flow chamber through an inlet opening of the flow chamber and emerging from the flow chamber through an outlet opening of the flow chamber, and which flow chamber has at least one means for changing the direction of the fluid flow at the outlet opening in a controlled manner. The flow chamber has a main flow channel, which interconnects the inlet opening and the outlet opening, and at least one auxiliary flow channel as a means for changing the direction of the fluid flow at the outlet opening in a controlled manner. The inlet opening has a larger cross-sectional area than the outlet opening or the inlet opening and the outlet opening have cross-sectional areas that are equal in size.

Abstract: Apparatus and method for a combustion turbine engine are provided. A pre-mixing passage (24) has an upstream inlet arranged to receive a flow of air to be mixed with fuel. A fuel-injecting lance (12) is disposed in the pre-mixing passage. At least a first fuel ejection orifice (40) is disposed at a first axial location of the fuel-injecting lance. At least a second ejection orifice (42) is disposed at a second axial location of the fuel-injecting lance. A spacing between the first and second axial locations is arranged to effect oscillatory interference patterns in pockets comprising mixtures of air and fuel that flow towards a downstream outlet of the pre-mixing passage. The oscillatory interference patterns may be effective to promote homogeneity in the mixtures of air and fuel and dampen thermoacoustic oscillations in a flame (46) formed upon ignition of the mixtures of air and fuel.

Abstract: A ducted combustion system includes a combustion chamber and a fuel injector in fluid connection with the combustion chamber, which includes an orifice opening from an injector tip of the fuel injector, the orifice injecting fuel into the combustion chamber as a fuel jet, the fuel jet flowing, within the combustion chamber, in a fuel flow direction. The system includes at least one duct disposed within the combustion chamber, the at least one duct being disposed such that the fuel jet, at least partially, enters one of the at least one ducts upon being injected into the combustion chamber. The at least one duct may be configured for having a flow field air stream within the duct, prior to entrance of the fuel jet, the flow field air stream having a flow direction that is substantially similar to the fuel flow direction.

Abstract: An engine has an engine body, an injector, and a control section which controls a fuel injection amount and an injection state of the injector. The control section predicts a state of temperature in the combustion chamber, and controls the injector such that a volume of an air-fuel mixture layer formed in the combustion chamber is larger when the predicted temperature is high, than when the predicted temperature is low, even when same fuel amounts are injected.

Abstract: A valve assembly for a fluid injection valve contains a hollow valve body which hydraulically connects a fluid inlet to an injection orifice and has a longitudinal axis. A valve needle is received in the valve body in an axially displaceable fashion for sealing the injection orifice in a closing position. An electromagnetic actuator assembly is provided for displacing the valve needle away from the closing position, the actuator assembly containing a movable armature and a pole piece which is positionally fixed relative to the valve body. A guide element is positionally fixed relative to the pole piece, has a first guide surface for axially guiding the armature and a second guide surface for axially guiding the valve needle.

Abstract: A fuel injector for supplying fuel to a fuel consuming devise includes a fuel inlet for receiving the fuel, a nozzle tip for dispensing the fuel from the fuel injector, a conduit for communicating the fuel from the fuel inlet to the nozzle tip, a valve seat, and a valve selectively seatable and unseatable with the valve seat for selectively preventing and permitting fuel flow out of the nozzle tip. The nozzle tip includes a non-circular recess on a downstream side thereof and a metering hole on an upstream side thereof opening into the non-circular recess to allow fuel to exit the nozzle tip, the metering hole having a smaller area than the non-circular recess.
