How carburetor works
A mechanical device that mixes a certain proportion of gasoline and air under the vacuum generated by engine operation. As a precision mechanical device, the carburetor uses the kinetic energy of the inhaled air flow to atomize gasoline. Its important role in the engine can be called the “heart” of the engine. The complete device should include starting device, idle device, medium load device, full load device and acceleration device. The carburetor will automatically proportion the corresponding concentration and output the corresponding amount of mixed gas according to the different working conditions of the engine. In order to make the mixed gas mixture evenly mixed, the carburetor also has the effect of atomizing the fuel for the normal operation of the machine.
Classification of carburetors
Carburetors are divided into simple carburetors and complex carburetors. Carburetors can also be divided into downdraft and flat-draft types. Carburetors can be divided into rotary type and lift type based on the type of throttle valve. The rotary throttle is a disc-shaped throttle that rotates around an axis between the carburetor throat and the intake pipe to change the flow area of the intake duct. The lift-type throttle is constructed as a barrel-shaped plate-shaped throttle, which moves up and down at the throat to change the channel area at the throat. This form is often used in motorcycle carburetors. There is also a type of carburetor that is a hybrid form of the two. The rotary throttle is controlled by a human and the lift throttle is controlled by a diaphragm. This is also often used on motorcycles and is called the CV type.
