Question: 1 / 400

Which component increases the air velocity and decreases the pressure in the carburetor?

Throttle

Choke

Venturi

The component that increases the air velocity and decreases the pressure in the carburetor is the Venturi. The throttle controls the amount of air flowing into the carburetor, but does not directly affect air velocity or pressure. The choke is used to restrict air flow during cold starts, but does not increase velocity or decrease pressure. The float is responsible for regulating the fuel level in the carburetor, and does not have any impact on air velocity or pressure. The Venturi, on the other hand, is a narrowing in the carburetor that creates a jet-like effect, increasing air velocity and decreasing pressure to create the optimal mixture of air and fuel for efficient combustion.
