High-altitude-area carburetor device

Abstract

In order to solve the problem that engine power of a carburetor in the high altitude area is affected, the invention provides a high-altitude-area carburetor device. The high-altitude-area carburetordevice comprises a carburetor body, the carburetor body comprises a float chamber and a float chamber cover, a main jet is arranged in the float chamber, a protrusion is arranged on the inner side ofthe float chamber cover, a channel is arranged in the protrusion, an electromagnetic valve is arranged on the outer side of the float chamber cover, and is connected with a first needle valve, an oilinlet is formed in the side wall of the channel, an opening is formed in the float chamber cover, a fuel oil adjusting device is further included, and comprises a needle valve part, the needle valve part comprises a second needle valve, the second needle valve is matched with the oil inlet, and a valve cover is arranged at the tail end of the second needle valve. Through the electromagnetic valve,the main oil inlet amount of the main jet can be rapidly controlled, the opposite position of the second needle valve and the oil inlet can be adjusted, the oil inlet amount of the main jet can be controlled, the valve cover is arranged at the tail end of the second needle valve, according to the air thinning degree, the positions of the second needle valve and the oil inlet can be precisely adjusted, and the air-fuel ratio of an engine is optimal.

Description

technical field [0001] The invention relates to the technical field of carburetors, in particular to a carburetor device for high altitude areas. Background technique [0002] The 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 automatically 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 o...
