FAQs
What is a venturi?
Venturi is a narrow passage, pipe, hose, or conduit that restricts airflow. That restriction forces air to speed up and drop in pressure. That low pressure vacuum zone is required for suction.
In a carburetor, that suction draws in fuel. It also atomizes the fuel and sends it to combustion.
What is a carburetor’s function?
- mixes air and fuel in the right ratio for an internal combustion engine to run,
- controls engine speed by regulating airflow through a narrow section (venturi).
