What does carburetion mean?
Carburetion is the process by which liquid or vaporized fuel is mixed with air before entering an engine cylinder. In a gasoline engine, a carburetor breaks the fuel into a fine spray and combines it with the incoming air, producing the combustible mixture the engine needs. The term is chiefly technical and historical: carburetion characterized many early- and mid-20th-century engines but was gradually displaced by electronic fuel injection, although some modern vehicles continue to use carburetors. Carburetion can also describe the quality of that mixing process, so engineers might report poor carburetion as a cause of rough idling, uneven running, or excessive fuel consumption. The word is uncommon in everyday conversation but remains useful in automotive history, mechanical engineering, and descriptions of older machinery. It names a technical process rather than the device that performs it: the carburetor is the component, while carburetion is the action taking place.
nounCarburetion is the process of mixing air with gaseous or vaporized fuel, especially in a gasoline engine, to produce a combustible mixture. It may also refer to the quality or degree of this mixing.
- The process of mixing air with fuel vapor to form the combustible mixture used in an internal-combustion engine.
"The mechanic blamed poor carburetion for the engine's rough idle."
"The mechanic blamed poor carburetion for the engine's rough idle."
"During the restoration, the team adjusted the carburetion of the vintage aircraft engine."
Rare; carburetion is normally a mass noun, but the plural can refer to distinct instances or types of the process.
"The manual compares the carburetions used in aircraft, marine, and automobile engines."
Before fuel injection took over, carburetion was the art of feeding an engine the right mix of air and fuel.

Where does carburetion come from?
Carburetion was borrowed into English from French carbureter, a verb associated with carbureting fuel and ultimately with French carbone, “carbon.” English formed the process noun with the suffix -ion during the early 19th century. Relatives such as carbon, carbonate, hydrocarbon, and carbide trace to the same Latin root, carbo, meaning “coal” or “charcoal,” although carburetion specifically refers to the mixing of fuel and air.
How carburetion is actually used
Chiefly technical and historical. The term is most often encountered in automotive and mechanical engineering, the restoration of older engines, and discussions of engines that predate electronic fuel injection.
Easily confused with carburetion
A carburetor is the component that mixes fuel with air, whereas carburetion is the mixing process itself.
