The venturi accelerates airflow and draws fuel into the airstream
The throttle valve regulates the volume of the air-fuel mixture entering the engine's cylinders
Multi-venturi carburetors provide a finely tuned air-fuel mixture for varying engine demands
Air bleeds improve atomization and mixture quality by introducing extra air into the fuel passages
Heated vaporizers promote better fuel atomization and enable the use of less volatile fuels
Feedback carburetors use oxygen sensors to dynamically adjust the air-fuel ratio for optimal catalytic converter function
Four-barrel carburetors adapt to changes in engine load by operating on two barrels for fuel efficiency and opening additional barrels for more power
These carburetors automatically adjust the venturi size to maintain consistent engine performance across different operating conditions
Primary and secondary barrels are calibrated differently to fulfill their roles in engine performance
Performance engines may use individual carburetors for each cylinder or group of cylinders for precise control over the air-fuel mixture
Iconic Ferrari V12 engines often feature six two-barrel carburetors for high performance and a distinctive sound
Multi-carburetor configurations demonstrate mechanical sophistication in performance engines
