Which component in this carburetor system sprays fuel into the intake manifold?

• A. Pumps
• B. Valves
• C. Nozzles
• D. Jets

Answer: (C)

Fuel has to be atomized before it enters the engine, and the thing that does the spraying is the nozzle inside the carburetor. The nozzle releases fuel into the incoming air stream so it can mix with air as it flows through the venturi and into the intake manifold. That atomized spray is essential for proper combustion.

Pumps push fuel into the carburetor, but they don’t spray it into the air. Valves regulate the flow, controlling when and how much fuel can pass. Jets set the amount of fuel that can flow at different operating conditions, but the actual spraying into the air stream happens at the nozzle.
