Plain English Meaning

A type of carburetor that uses pressure differences in the air entering the engine to push the right amount of fuel into the airflow. Because it does not depend on a small pool of fuel sitting in a chamber, it keeps working properly even when the aircraft is climbing, descending, or maneuvering.

Full Definition

A carburetor that meters fuel by sensing pressure differences across the airflow rather than relying on fuel sitting in an open float chamber. Fuel is delivered under pressure through a regulated system that responds to the pressure drop in the venturi and the impact pressure of incoming air, producing a more accurate fuel-air mixture across a wide range of flight attitudes and conditions.
