Carburetors mix oil and air into mist in proportion, and then enter the combustion chamber. Of course, the fault of carburetor is unstable idle speed. If the fuel consumption is serious, the car will not start.

The carburetor is near the engine cylinder and connected to the engine through the intake pipe, and the other end of the carburetor is connected to the fuel tank through the oil pipe. If it's a straddle bike, it's under the fuel tank and behind the engine. If it is bent down, it is blocked by the fender on the engine, but it can be seen from the hole on the left or right side of the fender. If it is a scooter, you need to remove the cargo box under the cushion to see the 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 airflow to atomize gasoline. Its important role in the engine can be called the "heart" of the engine. Its complete device should include starting device, idling device, medium load device, full load device and accelerating 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 mix the mixture evenly, the carburetor also has the function of atomizing fuel for the normal operation of the machine.

Carburetors are divided into simple carburetors and complex carburetors. Carburetors can also be divided into downward suction type and horizontal suction type. According to the type of throttle, carburetor can be divided into rotary type and lifting type. The rotary throttle valve is a disc-shaped throttle valve, which rotates around the axis between the carburetor throat and the intake pipe to change the flow area of the intake pipe. The lifting throttle valve is a bucket-shaped plate throttle valve, which moves up and down in the throat to change the channel area of the throat. This form is often used in motorcycle carburetor. There is also a carburetor that is a mixture of the two. The rotating throttle is controlled by people, and the lifting throttle is controlled by diaphragm, which is also often used on motorcycles and is called CV type.
