Description

Technical Field

[0001] The utility model relates to the technical field of auto parts, in particular to a plastic carburetor. Background Art

[0002] The carburetor is a mechanical device that mixes a certain proportion of gasoline and air under the vacuum generated by the engine. The carburetor uses the throat to generate vacuum, drive the internal piston to move, and form a gasoline-air mixture. The emergence of plastic carburetors is for environmental protection, because metal carburetors need to have a richer mixture in order to obtain better starting performance during cold start, which will result in a certain amount of exhaust emissions that do not meet the standards. The plastic carburetor has a more moderate oil-gas mixture ratio, which not only reduces pollutant emissions and effectively protects the environment, but also improves engine combustion efficiency and saves fuel.
