Abstract

The invention relates to an electric vehicle extend range power improved type membrane type carburetor. The electric vehicle extend range power improved type membrane type carburetor comprises a carburetor body. An air inlet channel penetrating the carburetor body is arranged in an upper body of the carburetor body. An oil atomization cavity used for storing fuel oil is formed in the lower side face of the carburetor body. A negative pressure adjusting device used for controlling an oil tank to feed oil into the oil atomization cavity is arranged at the lower portion of the carburetor body. The oil atomization cavity is located above the negative pressure adjusting device, and accordingly the side, located in the oil atomization cavity, of the negative pressure adjusting device is subjected to uniform oil immersion through the fuel oil in the oil atomization cavity. The horizontally-arranged negative pressure adjusting device is adopted, a negative pressure elastic film is subjected to even oil immersion, the situation that due to different oil erosion degrees of the negative pressure elastic film, a local part is seriously damaged is prevented, and the quality problem that due to physical performance changes during negative pressure elastic film deformation, oil supply of the carburetor is poor is solved.

Description

technical field [0001] The invention relates to the technical field of carburetors, in particular to an improved diaphragm carburetor for electric vehicles with extended range power Background technique [0002] As a precision mechanical device, the carburetor uses the kinetic energy of the inhaled air flow to realize the atomization of gasoline. Specifically, it is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine. Its important role in the engine can be called the "heart" of the engine. According to the requirements of different working conditions of the engine, the carburetor will match the corresponding concentration through mechanical debugging, and output the corresponding amount of mixed gas. [0003] Common carburetors control oil intake through floats, but there are also carburetors that do not use floats to control oil intake on the market, such as carburetors that use negative pressure to control oil...
