Carburetor suitable for srm210 srm211 gt200 pe200 hc150 shc210 trimmerA carburetor is a fuel supply system for an internal combustion engine, mainly used in automobiles, motorcycles, ships and other internal combustion engine equipment. Its function is to mix liquid fuel (usually gasoline) and air into a combustible gas for the engine to burn. The main components of a carburetor include: Intake pipe: used to introduce air into the carburetor. Throttle valve: a device that controls the air flow. By operating the throttle valve, the engine speed and power output can be adjusted. Nozzle: used to spray fuel, atomize gasoline and mix it with the air entering the engine. Float chamber: stores and controls the flow of fuel, maintains a constant fuel level in the carburetor to ensure the stability of the engine's fuel supply. Mixing chamber: located above the float chamber, used to mix fuel and air to form a combustible gas. Fuel pump: used to increase the pressure of the fuel supply in some high-performance engines or special working conditions to ensure the normal operation of the engine. The working principle of the carburetor is based on the air entering the mixing chamber through the throttle valve, and the gasoline injected from the float chamber through the nozzle also enters the mixing chamber. In the mixing chamber, gasoline mixes with the incoming air to form a combustible mixture. The mixture then enters the engine through the intake pipe, where it is compressed and ignited before burning to drive the engine.
