A carburetor has a carburetor body having a venturi passage that conveys air from an air inlet to an air outlet. A throttle valve controls flow of the air in the venturi passage. The throttle valve is movable into a closed position, an open position, and at least one transition position between the closed position and the open position. A fuel bowl holds fuel for mixing with the air in the venturi passage. A main nozzle discharges the fuel from the fuel bowl to the air in the venturi passage when the throttle is in the open position. A secondary circuit that is smaller than the main nozzle discharges fuel from the fuel bowl to the air in the venturi passage when the throttle is in the closed position, the transition position, and the open position. A filter is configured to remove particulate matter from the fuel in the fuel howl prior to discharge via the secondary circuit. Methods are for making the carburetor and operating the carburetor.

The present disclosure generally relates to an engine with an integrated mixing of fluids device and associated technology for improvement of the efficiency of the engine, and more specifically to an engine equipped with a fuel mixing device for improvement of the overall properties by inline oxygenation of the liquid, a change in property of the liquid such as cooling form improved combustion, or the use of re-circulation of exhaust from the engine to further improve engine efficiency and reduce unwanted emissions.

A gaseous fuel and air mixing venturi device is adapted for installation in a gaseous fuel carburetor and has a venturi body defining annular inner and outer venturi passageways which each have a throat of reduced cross-sectional area and have inlet ends in communication with an air inlet of the carburetor. A fuel inlet is configured for connection to a fuel port of the carburetor, and communicates with a plurality of fuel supply ports in the body communicating radially with the inner and outer venturi passages to mix with the air flowing in the passageways.

The present invention generally relates to a method and device that enhances fuel atomization in a carburetor or a similar apparatus. Specifically, it introduces a unidirectional fuel nozzle that is designed to improve the atomization of fuel injected into the fuel-air mixing chamber of a combustion engine. The fuel nozzle comprises a cylindrical body with a plurality of perforations on one half and a plurality of dimples on the outer surface of the other half. Each dimple is designed with an air turbulator, which creates turbulence on the surface of the fuel nozzle in response to the air pressure, delaying the separation of the air from the surface of the fuel nozzle. As a result, fuel droplets break down further, improving fuel atomization. This enhances the combustion efficiency of the engine by allowing the fuel to mix with air more effectively.
