Range extender carburetor. How does gasoline flow directly to the gasoline engine side?

Gasoline engine in carburetor era! ? …

1. Zip accelerator is the accelerator pedal with a line connected to the accelerator. Pulling that line is actually to increase the throttle opening.

2. The air from the intake pipe first enters the carburetor and then the throttle. Because the piston of the engine moves, a vacuum (negative pressure) will be generated, and atmospheric pressure will push air into the engine.

The carburetor is full of gasoline and there is a small hole leading to the intake pipe. Due to the pull wire, the throttle opening becomes larger, and more gas is washed into the intake pipe, so that the carburetor is affected by the pressure difference near the intake pipe orifice, and the gasoline liquid flows out. Under the action of airflow, it becomes a finer liquid gasoline state and enters the engine for combustion.

In other words, the gasoline in the carburetor is actually "sucked".
