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 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.

摘要： A fuel injection valve in which, even in an engine in which a fuel containing many foreign matters is used, pinching of solid foreign matters, such as impurities, dirt and dust, and combustion residues, in a sliding part on the outer periphery of a needle valve, the tip of the needle valve, and a seat of a nozzle tip, malfunction an seizure of the needle valve due to such containing, and poor combustion due to irregular injection are prevented from occurring.The fuel injection valve has a first groove cut in the periphery surface of the needle valve and the second grooves cut in a seat surface of the nozzle tip. The first groove is provided so that the needle valve is rotated by flow of the fuel in the first groove caused by reciprocating motion of the needle valve, and the upper and lower ends of the first groove are opened to the outside so that a part of fuel can be introduced in to the groove. The second grooves are twisted or tilted in the same direction as the rotating direction of the needle valve and are cut along the circumferential direction of the nozzle tip. The second grooves have an edge part for scraping off solid matters in the fuel into the second grooves in cooperation with of the tip seat surface of the needle valve affected by the rotation of the needle valve.
