Anti-toppling carburetor structure based on external fuel oil container

Abstract

The invention discloses an anti-toppling carburetor structure based on an external fuel oil container. The anti-toppling carburetor structure comprises a float type carburetor, a float chamber and at least one external fuel oil container, wherein the float chamber is formed inside the carburetor; the external fuel oil container is arranged outside the carburetor; the bottom of the fuel oil container is communicated with the float chamber in the carburetor. According to the technical scheme, regardless of the inclination angle of an engine, fuel oil in the float chamber of the carburetor cannot be leaked out through a main spraying pipe, a main air channel or an idling channel, and the effects of saving fuel, preventing the environment pollution and the potential safety hazard and improving the reliability of the engine are achieved; moreover, according to the structure, only an oil cup of an original carburetor needs to be changed, a carburetor body does not need to be corrected, and the structure has the advantages of simplicity in implementation, low cost and high reliability.

Description

technical field [0001] The invention belongs to the technical field of engine carburetor anti-dumping, and more specifically refers to a carburetor anti-dumping structure based on an external fuel container. Background technique [0002] The structure of the fuel supply system of the carburetor engine is relatively simple and cost-effective. It is widely used in general engines, generator sets, water pumps, garden machinery, agricultural machinery, ships and other industries. [0003] The carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the negative pressure of the cylinder generated by the movement of the engine piston. There is a float with a needle valve in the float carburetor, and the external fuel enters the carburetor through the oil inlet nozzle. Under the buoyancy of the float, the needle valve can control the opening and closing of the oil inlet valve connected to the oil inlet nozzle to stabilize Fuel level in float cha...

AI Technical Summary

Problems solved by technology

but if figure 2 As shown, when the carburetor 10 tilts to the left to a horizontal state, due to the large amount of fuel in the float chamber 1012, the fuel level 8 is higher than the bottom opening 1007 of the upper oil pipe, and the fuel floods the main nozzle pipe 1008 and the idle speed channel 1010, at this time the fuel will leak from the main nozzle 1008 and the idle channel 1010

Obviously, when the existing carburetor 9 tilts to the right side to a horizontal state, the fuel level 8 will also be higher than the bottom opening 1007 of the oil pipe, and the fuel in the float chamber 1012 will submerge the main air passage 1009, and the fuel will be will leak from the main air channel 1009
