What is a carburetor?

Carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by engine operation. As a precise mechanical device, carburetor uses the kinetic energy of inhaled air flow to atomize gasoline. Its important role in the engine can be called the "heart" of the engine. Its complete device should include starting device, idle device, medium load device, full load device and acceleration device. The carburetor will automatically match the corresponding concentration and output the corresponding amount of mixed gas according to the requirements of different working conditions of the engine. In order to make the mixed gas mixed evenly, the carburetor also has the effect of atomizing the fuel for the normal operation of the machine.

The main classification of carburetors

Carburetors are divided into simple carburetors and complex carburetors. Carburetors can also be divided into down-suction and flat-suction types. The carburetor is divided into rotary type and lifting type from the type of throttle. The rotating throttle valve is a disc-shaped throttle valve that rotates around the axis between the carburetor hose and the intake pipe to change the flow area of the intake tract. The lifting throttle is structured as a barrel-shaped plate-shaped throttle, which moves up and down at the throat to change the channel area at the throat, and motorcycle carburetors mostly use this form. There is also a carburetor is a hybrid form of the two, using a person to control the rotating throttle, with a diaphragm to control the lifting throttle, which is also often used on motorcycles, called CV type.
