What is the primary purpose of a carburetor?

The primary purpose of a carburetor is to mix fuel and air in the appropriate ratio to support combustion within an internal combustion engine. This mixing process is critical because an engine requires a specific blend of air and fuel to operate efficiently, ensuring optimal power production and performance. The carburetor atomizes the fuel and combines it with air, allowing it to be drawn into the engine’s combustion chamber.

An effectively functioning carburetor contributes to smoother engine operation, better fuel efficiency, and reduced emissions. If the mix is not correct, the engine may run rich (too much fuel) or lean (too much air), leading to performance issues and potential engine damage. This function is fundamental to an engine's operation, making the carburetor vital for its overall effectiveness.

The other options do not accurately outline the primary function of a carburetor. Storing gasoline pertains to fuel tanks, maintaining engine speed relates to throttle mechanisms or governors, and cleaning air entering the engine typically involves air filters and not the carburetor itself.
