The Role of the carburetor is:
It atomizes gasoline and mixes with air to form a combustible mixture, which is then fed into each cylinder.When gasoline by gasoline pump into the carburetor float chamber, in float indoor one empty, it can form in the gas pressure and nozzle (vacuum) pressure difference, oil injection directly to roar, into the oil mixed with the roar of upper tube through the air cleaner air, carburetor and also five systems, the main oil supply, idle, add thick, acceleration and starting.
Provide a certain amount and concentration of flammable mixture under various engine starting, cold starting, acceleration, idle speed, normal operation and so on.It includes the main oil supply system, idle oil supply system, excessive nozzle, acceleration pump, throttle, atomizing throat, choke, fast idle mechanism, air conditioning speed mechanism, oil plane float adjustment device and other devices, using the siphon effect of the high-speed air flow through the main and secondary chamber to suck out the gasoline from the float chamber.At the same time, the gasoline is broken into fine particles to form a preliminary mixture by the cutting effect of the air flow, and then the combustible gas is formed by heating and evaporation through the intake manifold and the inlet valve piston.
The air flows through the carburetor at a higher velocity under the suction of the intake stroke.
The air flows through the carburetor throat (the area of the airway cross-section is reduced) to form a vacuum degree, and the nozzle nozzle connecting the float chamber is also at the throat. The oil is sucked out of the nozzle, and the high-speed air intake will be blown and atomized by the gasoline inhaled into the carburetor throat to form a combustible mixture into the cylinder.
