Classification of carburetor
Carburetors are divided into simple carburetor and complex carburetor. The carburetor can also be divided into a down suction type and a flat suction type. The carburetor is divided into two types: the throttle type and the lift type. The rotary throttle valve is provided with a disc-shaped throttle valve that rotates around the shaft between the carburetor throat and the intake pipe to change the flow area of the intake passage. The lift type throttle is constructed as a barrel-shaped throttle valve, which moves up and down at the throat to change the passage area at the throat. The motorcycle carburetor adopts this form. There is also a carburetor that is a mixture of the two. The person controls the rotary throttle and uses the diaphragm to control the lift throttle. This is also commonly used on motorcycles, called CV.
