Abstract

The invention provides a carburetor comprising a carburetor main body. The carburetor is characterized in that the carburetor main body comprises a plunger passage, an intake chamber, a mixing chamberand a fuel chamber, wherein the intake chamber is provided with an air intake, an idle and low speed intake pipe and a choke valve, the mixing chamber is provided with a mixed gas outlet, and the fuel chamber is communicated with the mixing chamber through a main fuel metering tube; a needle valve is arranged between the plunger passage and the main fuel metering tube; the fuel chamber is internally provided with an atmospheric passage, a float valve subassembly and an idle fuel supply system; one end of an intake passage is communicated with the fuel chamber while the other end is communicated with an intake chamber; the float valve subassembly is arranged at the end where the atmospheric passage is communicated with the fuel chamber; the idle fuel supply system comprises an idle and lowspeed measuring tube and a mixing ratio screw; the idle and low speed measuring tube is communicated with one end of the low speed intake pipe. The carburetor has the advantages of changing the amount of air intake so as to be suitable for alcohol-based fuels, being improved and simple, and solving the problem that an existing carburetor can not burn using fuel with low combustion value.

Description

technical field [0001] The invention relates to a carburetor comprising a carburetor main body. Background technique [0002] With the increasing shortage of oil resources and the deterioration of the natural environment, the state has gradually strengthened the regulation of pollution emissions, and at the same time paid more and more attention to finding alternative energy sources. Alcohol-based biofuels and methanol gasoline are popular because of their wide range of raw materials, good environmental protection benefits and some renewable energy. Applying alcohol-based fuels and methanol gasoline to motorcycles and other vehicles can significantly play a role in energy saving and emission reduction. However, The gasoline carburetors currently used in gasoline motorcycles cannot use fuels with low combustion values, such as alcohol-based biofuels. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the object of the prese...
