Problems solved by technology

[0004] Most of the existing multi-chamber carburetors are dual-chamber split type, but there is a problem that the air pressure ratio is not easy to adjust, and manual adjustment and trial are required, so the corresponding intake ratio and mixing ratio also need to be adjusted. The process is very cumbersome, which greatly reduces the practicability of the carburetor

Abstract

The invention discloses a multi-chamber carburetor structure. The multi-chamber carburetor structure comprises a carburetor body, wherein the carburetor body comprises an oil-gas mixing chamber shell;a first throat pipe chamber and a second throat pipe chamber are formed in the oil-gas mixing chamber shell in a penetrating manner side by side; a first vacuum membrane cushion chamber and a secondvacuum membrane cushion chamber are separately symmetrically arranged at the upper end of the first throat pipe chamber and the upper end of the second throat pipe chamber; a first vacuum membrane anda second vacuum membrane are transversely glued to the inside of the first vacuum membrane cushion chamber and the inside of the second vacuum membrane cushion chamber separately; the lower end air chamber of the first vacuum membrane and the lower end air chamber of the second vacuum membrane separately communicate with the first throat pipe chamber and the second throat pipe chamber; the upperend air chamber of the first vacuum membrane and the upper end air chamber of the second vacuum membrane separately communicate with the insides of two air pressure detection devices; and the two airpressure detection devices are separately connected with air pressure adjusting valves through air pipes. The multi-chamber carburetor has a good regulation and control effect on the working state ofan engine; manual regulation and test steps are omitted; and the practicability of the carburetor is improved well.

Description

technical field [0001] The invention mainly relates to the technical field of carburetors, in particular to a structure of a multi-chamber carburetor. Background technique [0002] A carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine. As a precise mechanical device, the carburetor uses the kinetic energy of the inhaled air flow to realize the atomization of gasoline. Its important role in the engine can be called the "heart" of the engine. Its complete device should include starting device, idle speed device, medium load device, full load device and acceleration device. The carburetor will mix the corresponding concentration according to the requirements of different working conditions of the engine, and output the corresponding amount of mixed gas. In order to make the mixed gas mixed evenly, the carburetor also has the function of atomizing the fuel. effect for the normal operation of the machi...
