The present disclosure discloses a carburetor, including a fuel passage and an oil passing passage. The fuel passage communicates with the float chamber. The carburetor further includes a magnetic sleeve assembly, a magnet assembly and a thimble assembly. The magnetic sleeve assembly is fixed to a float base and a first end of the magnetic sleeve assembly extends into the oil passing passage and is connected to a body. The first end of the magnetic sleeve assembly includes a fuel passing hole and a passage, the fuel passing hole communicates with a float chamber. The passage communicates the oil passing passage. Both the thimble assembly and the magnet assembly are installed in the magnetic sleeve assembly. The thimble assembly is configured for cutting off the passage under driving of the magnet assembly to cut off a communication between the oil passing passage and the float chamber.

In one aspect of the present invention carburetor comprises a hollow first cylinder and a hollow second cylinder. In one embodiment, hollow first cylinder comprising plurality of nozzles formed on the lateral surface and nozzles providing flow path for a fuel to flow from the hollow region to outside of the later surface of the first cylinder. In another embodiment, hollow second cylinder placed on the first cylinder and the axis of the first cylinder and the second cylinder coincide. In another aspect of the present invention, sliding the second cylinder over the first cylinder, and number of nozzles through which fuel flows out increases when the outer cylinder is slide in first direction. In one embodiment, the first cylinder is placed in a first region through which air is sucked into the combustion chamber. In another embodiment, a throttle control operative to increase the engine power, may be coupled to the second cylinder such that increasing throttle pulls the second cylinder in the first direction.

A fuel discharge nozzle for discharging fuel into an airflow passageway of a barrel of a carburetor includes a nozzle body that is attached to the carburetor and has proximal and distal ends. The nozzle body defines a fuel inlet that receives fuel, a fuel outlet that permits the fuel to flow out of the nozzle body, and a fuel passage fluidly connecting the fuel inlet and the fuel outlet so that the fuel can flow from the fuel inlet to the fuel outlet. The nozzle body is sized and shaped to position the fuel outlet in the airflow passageway of the barrel of the carburetor when the nozzle body is attached to the carburetor so that the fuel flows into the airflow passageway of the carburetor and mixes with air after the fuel flows out of the fuel outlet.

A fuel discharge nozzle for discharging fuel into an airflow passageway of a barrel of a carburetor includes a nozzle body that is attached to the carburetor and has proximal and distal ends. The nozzle body defines a fuel inlet that receives fuel, spaced apart fuel outlets disposed between the proximal and distal ends of the nozzle body that permit the fuel to flow out of the nozzle body, and a fuel passage fluidly connecting the fuel inlet and the fuel outlets so that the fuel can flow from the fuel inlet to the fuel outlets. The nozzle body is sized and shaped to position the fuel outlets in the airflow passageway of the barrel of the carburetor when the nozzle body is attached to the carburetor so that the fuel flows into the airflow passageway of the carburetor and mixes with air after the fuel flows out of the fuel outlets.

Underwater gas pressurization units and liquefaction systems, as well as pressurization and liquefaction methods are provided. Gas is compressed hydraulically by a rising pressurization liquid that is separated from the gas by a water immiscible liquid layer on top of an aqueous salt solution. Tall vessels are used to reach a high compression ratio that lowers the liquefaction temperature. The pressurizing liquid is delivered gravitationally, after gasification, transport to smaller water depths and condensation. Cooling units are used to liquefy the compressed gas. A cascade of compression and cooling units may be used with sequentially higher liquefaction temperatures, which allow eventual cooling by sea water. The pressurizing liquid, dimensions of the vessels, the delivery unit, the coolants and the implementation of the cooling units are selected according to the sea location, to enable natural gas liquefaction in proximity to the gas source.
