    摘要: A fuel injector may include a housing, a pintle nozzle assembly and an actuation assembly. The housing may define a longitudinal bore, a high pressure fuel duct in communication with the longitudinal bore and a valve seat including a valve seat surface and an aperture. The pintle nozzle assembly may include a stem and a pintle and may be at least partially disposed within the longitudinal bore and be variably displaceable between a first position and a second position. In the first position, the pintle nozzle assembly may abut the valve seat to seal the aperture. In the second position, the pintle nozzle assembly may be displaced from the valve seat to open the aperture. The actuation assembly may be coupled with the pintle nozzle assembly and operate to move the pintle nozzle assembly to a plurality of positions between the first position and the second position.

    摘要: Methods, systems, and devices are disclosed for delivery a fluidic substance using Lorentz forces. In one aspect, a method to accelerate particles into a chamber includes distributing a fluidic substance between electrodes configured at a location proximate a chamber, in which electrodes include a low work function material, generating a current of ionized particles by applying an electric field between the electrodes to ionize at least some of the fluidic substance, and producing a Lorentz force to accelerate the ionized particles into the chamber. In some implementations, the method further includes applying an electric potential on an antenna electrode interfaced at the port to induce a corona discharge into the chamber, in which the corona discharge ignites the ionized particles within the chamber.

    摘要: A fuel injector-igniter incorporating adaptive swirl injection and ignition. The fuel injector-igniter comprises a housing, an actuator, and a valve. The valve includes a valve head operative to open and close against a valve seat in response to activation of the actuator. The valve seat includes an electrode portion extending beyond the valve head and within the housing to form at least one gap, such as an annular gap. A current discharge between the housing and electrode portion establishes a plasma and electromagnetic forces driving the plasma from the gap. The injector-igniter may further comprise a power supply connected to the housing and valve seat that is operative to provide the current discharge. The electrode portion includes a plurality of flow shaping features, such as a plurality of twisted fins disposed around the electrode portion and thereby operative to impart a rotation to the plasma.

    摘要: A pressure swirl atomizer has a swirl chamber with an exit orifice and a plurality of tangential swirl channels disposed around the circumference of the swirl chamber. A pintle bearing surrounds a pintle. The pintle has a body portion and a nose portion that is narrower than the body portion. The nose portion has a tip that opens and closes the exit orifice and a side that is movable in the pintle bearing. In one embodiment, a return path formed between the nose portion of the pintle and the pintle bearing drains fluid from the swirl chamber when the exit orifice is closed. The nose portion positions the return path closer to a centerline of the atomizer, forcing fluid to swirl in the swirl chamber before draining. Since the fluid does not remain static in the chamber, less energy is needed to increase the fluid velocity and quickly form a desired spray pattern when the exit orifice is opened.
