A butterfly valve carburetor is a fuel supply device commonly used in small general-purpose gasoline engines. Its core design lies in precisely controlling airflow through the rotation of the butterfly valve to achieve an ideal mixture of fuel and air, th
The butterfly valve carburetor precisely controls the cross-sectional area of the intake passage through the rotation of the butterfly valve, thereby achieving dynamic adaptation of the throttle response under different operating conditions.
The opening control of the rotary valve also needs to be matched with the engine's ignition system, intake manifold design, etc., in order to achieve the optimization of overall performance.
The butterfly valve carburetor achieves precise control of the air-fuel ratio at different speeds through a clever combination of mechanical structure and fluid dynamics.
The valve body typically uses a high-precision machined conical or cylindrical channel. By rotating it, the cross-sectional area of the airflow is changed, thereby regulating the amount of air entering the throat of the rotary valve carburetor.
In low-temperature environments, the mechanical properties and chemical stability of carburetor components may change, leading to decreased sealing or increased wear.
