Abstract

An improvement scheme for a throttle valve piston of a fuel engine carburetor. At the lower end of the throttle valve piston of the carburetor, there are more than 2 comb-shaped guide grooves on the side of the engine, which are used to convect the mixed gas flowing through the throat when the throttle is small to realize multi-strand diversion. The dispersed gasoline after diversion is easier to combine with air and mix evenly, so as to improve the degree of atomization of oil and gas mixing, and realize fuel combustion more fully and quickly, so as to achieve the purpose of stable idle speed, energy saving and emission reduction.

Description

technical field [0001] The invention relates to a fuel engine carburetor, in particular to a throttle valve piston in an engine carburetor. Background technique [0002] The lower end of the throttle valve piston in the existing fuel engine carburetor is mostly planar by the side of the engine. [0003] Fuel is ejected from the carburetor foam tube 5 under the negative pressure suction of the air sucked by the piston in the engine cylinder equipped with a carburetor, and then mixed and atomized with the high-speed air flow entering the throat, and finally enters the engine cylinder The combustion chamber is ignited by the spark plug to generate high-temperature and high-pressure instantaneous explosion gas, which drives the piston and drives other mechanical parts to move and do work. [0004] The lower end of the throttle valve piston in the existing carburetor is mostly planar by the side of the engine. A mixed air flow flows to the engine, so gasoline is not easy to be ...
