How does venturi of a carburetor works?

The venturi of a carburetor works by creating a narrowing in the airflow path, which increases the speed of the air as it passes through. According to Bernoulli's principle, this increase in velocity results in a decrease in pressure, causing fuel from the carburetor's float chamber to be drawn into the airstream. This mixture of air and fuel is then atomized and delivered into the engine's intake manifold for combustion. The design ensures proper fuel atomization and mixing with air, which is crucial for efficient engine performance.
