Abstract: Systems and methods for injecting and mixing a liquid hydrocarbon fuel to provide a uniform, homogenous fuel vapor mixture for introduction into a fuel reformer for use with a fuel cell are disclosed. Preferably, the system comprises a fuel injector that generates and aspirate a liquid fuel in the presence of an atomizing gas stream; a diverging-converging mixing chamber, into which the atomized fuel and a secondary fluid stream are introduced, to enhance the mixing of the fuel and the added heated gas or steam; and a mixer/swirler, which can be centrally located in the mixing chamber between the upper and lower chambers, to stabilize the fuel vapor mixture further for greater uniformity and homogeneity. More preferably, grooves and/or brazed wires can be provided on the surfaces of the mixing chamber and/or mixer/swirler to channel any accumulated fuel so as to provide sufficient time to evaporate the accumulated fuel.

Abstract: A carburetor for an internal combustion engine has an intake pipe 30 having a throttle valve plate 41 therein. An annular venturi tube 20 is disposed upstream or downstream of the throttle valve plate 41 inside the intake pipe 30. The annular venturi tube 20 is located at a predetermined interval with the throttle valve plate 41. The annular venturi tube 20 has a fine continuous annular slit or four or more annularly arranged fuel discharging pores 27 so as to atomize the fuel thereat. Atomization is always carried out near a position where a fastest air moves so as to improve the atomization and obtaining a uniform air-fuel mixture, thereby improving an output, fuel consumption and exhaust gas emission of the internal combustion engine.

Abstract: An idle fuel supply device for a carburetor has an idle air passage that communicates with an air intake passage and a fuel chamber. A passage extending from a fuel metering chamber is connected to the fuel chamber preferably via a fuel adjusting needle valve. A low speed fuel nozzle hole communicates the fuel chamber with the air intake passage in the vicinity of a throttle valve when in its idle position. A passage communicates with the fuel chamber and the idle air passage, so that fuel and air may mix in at least a portion of the idle air passage.

Abstract: A fuel processing device is provided that produces properly sized fuel aerosol particles that when mixed with combustion air, reduces or eliminates detonation (knock) in internal combustion engines thus reducing fuel octane requirements for engines of a given compression ratio and increasing efficiency of the engine. The device includes an adapter between a fuel injector and a port for the fuel injector, the adapter being generally of a hollow cylindrical configuration closed to external gasses at an end that sealably receives the fuel injector. A plurality of plates are disposed in the adapter, the plates provided with a central opening, with radially extending slots extending away from the central opening. Each slot may have one edge configured with a vane that creates turbulence in the air/fuel mix passing through the adapter so that larger droplets are broken up into smaller droplets until an optimum droplet size is reached. A first plate may be configured to spread out the spray from the fuel injector so that the spray is processed by following plates.

Abstract: This disclosure relates to a centrifugal vortex system for preparing a liquid, such as fuel and includes a chamber housing defining a vortex chamber An array of tangential apertures are formed in the chamber housing to permit fluid to be turbulently introduced into the vortex chamber to create a vortical flow of fluid through the vortex chamber. In one embodiment, a plurality of vortex chambers are arranged in series to allow the fluid to pass through several vortex chambers. In other embodiments, the chamber housing may be stepped, textured, or both to increase the turbulence of the flow through the chamber. In yet another embodiment, a pressure differential supply jacket is provided to normalize the amount of flow through the tangential apertures according to the location of the apertures. A centrifuge chamber is also disclosed which has a plurality of output conduits on a bottom surface and a tapered extension member downwardly extending from a top surface to enhance the centrifugal flow of the fluid. Additionally, a bypass conduit is provided to selectively permit the flow to bypass one or more chambers.

Abstract: A carburetor device (10) having a plurality of apertures (12) circumferentially positioned and equally spaced around an orifice (14) portion of the carburetor device (10). The apertures (12) have a cross sectional area dimensioned to allow an air-fuel mixture to flow therethrough when a throttle member requires maximum power and corresponding air-fuel flow rates. The apertures (12) direct the air-fuel flow (30) through a “puddle” (27) of fuel that has accumulated in the bottom portion (28) of an outer well (18) of the carburetor (10) during the normal operation of an internal combustion engine. When maximum power is required from the engine, the increased air-fuel flow through the apertures (12) causes the fuel puddle (27) to vaporize or “mist”, allowing the fuel to become a part of the air-fuel flow stream supplying the engine's cylinders (25) thereby increasing the engine's power and response while decreasing the engine's hydrocarbon emissions.

Abstract: A carburetor for small engines which can be used in all positions utilizes a cylindrical rotary throttle valve with a venturi opening and provides a porous material as a part of the throttle valve, either as the entire material for the valve, or as a sleeve surrounding the venturi portion. During idling the fuel which might collect in a pocket in the valve is absorbed into the porous material and sucked into the engine, thus avoiding the disadvantages of liquid fuel being dumped into the engine when the position of the carburetor is changed.

Abstract: An automatically regulated variable orifice desuperheater valve is disclosed which includes improved constructional features providing for a more compact installation then heretofore, one which is more reliable in operation and which is at the same time more economical to construct. The desuperheater unit has a welded-closed housing, which includes a concentrically mounted valve guide structure. The lower portion of the desuperheater valve housing structure is arranged so that, after the unit is welded closed, with the valve guide structure contained therein, the valve element may be inserted into the housing from the bottom or inlet opening, followed by a shouldered sleeve which functions as the valve seat. The sleeve is seated against a facing shoulder in the inlet opening of the valve housing, and is secured against such shoulder by appropriate means such as welding. The housing surrounding the valve and valve guide is of minimum height, sufficient to accommodate the flow of steam and injected water around the valve and valve guide, and quickly converges the flow of materials back to the diameter of the main piping systems. The construction of the new device is more rugged and compact than previous designs, significantly less costly to construct, and at the same time superior in performance.
