Present disclosure relates to a injector, which comprises a first lance, provisioned with at least one first inlet port, to receive a first fluid. Further, a second lance is coaxially disposed within the first lance, and provisioned with at least one second inlet port, to receive a second fluid. The injector further includes a tube member, disposable within the second lance to receive the first fluid at one end, while sealed at another end. The tube member is provisioned with at least one recess for the first fluid in the tube member to mix with the second fluid and form the effervescent fluid. The effervescent fluid is then dispensed through at least one of a first exit port of the first lance and a second exit port of the second lance. The injector may be employed in applications such as, fuel injection, spray coating and the like.

A fuel supply device has a housing and an intake channel section formed in the housing. At least one fuel port opens into the intake channel section. At least one fuel channel is provided and a valve with valve plate is arranged in the fuel channel. The valve has a closed position and an open position. The valve plate contacts a valve seat in the closed position. The valve plate carries out a valve stroke between open position and closed position. At least one annular gap is formed in the fuel channel. A gap width of the at least one annular gap is matched to a length of the valve stroke of the valve plate such that the gap width is not larger than twice a length of the valve stroke. A flow cross section of the annular gap is larger than a flow cross section of the valve.

Method for optimizing the limitation of dust emissions from a gas turbine or combustion plant comprising a line for supplying liquid fuel oil, a line for generating fuel oil atomizing air, and a central controller, wherein: a first definition step, starting from a nominal temperature of the fuel oil and a nominal pressure ratio of the atomizing air of the fuel oil, and by controlling the injection of the soot inhibitor, of a nominal operating point corresponding to the maximum permissible level of emitted dust; a second step of controlling a first parameter, taken from the group of the fuel oil temperature and the pressure ratio of the fuel oil atomizing air, in order to reach another operating point; and a third step of controlling the soot inhibitor injection to achieve the maximum permissible level of emitted dust.

A dual fluid injection system which comprises a liquid fuel metering device, a fluid delivery device, and apparatus providing an interface therebetween. The interface conveys liquid fuel along a flow path from the metering device to a mixing zone for mixing with air from a pressurized supply to provide an air-fuel mixture for injection by the fluid delivery device into a combustion chamber of an internal combustion engine. The flow path may involve a directional change by way of a turn section. The flow path is sized such that liquid fuel is retained therein by virtue of capillary action, whereby a quantity of liquid fuel is retained after a delivery event such that the flow path remains substantially filled with liquid fuel in readiness for the next delivery event during operation of the engine.

An injection gate (44,144,244,344) for high pressure, high velocity secondary fluid for admixture of an atomized spray (80,180) thereof with another or primary fluid that atomizes the other fluid. The secondary fluid may be an accelerant and the primary fluid may be a low pressure fuel/air mixture in a fuel injection arrangement for an internal combustion engine. An injection billet (10,110,210,310) for an engine is interposed between the carburetor (12) and the manifold (14), with an array of such injection gates (44,244,344) paired with an array of fuel/air gates (34,234,334) about an aperture coinciding with a throttle bore (60,160,260,360) and evenly balancing the spray about the throttle bore, creating a halo effect of atomized admixture of accelerant/fuel. The injection of accelerant is directed sharply downwardly toward the center of the bore and through the injected fuel stream, atomizing the fuel thereof for a high efficiency boost of horsepower.

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.
