A
carburetor (
American and
Canadian spelling),
carburator,
carburettor, or
carburetter (
Commonwealth spelling) is a device that blends air and fuel for an
internal combustion engine. It is sometimes colloquially shortened to
carb in North America or
carby in Australia. To
carburate or
carburet (and thus
carburation or
carburetion, respectively) is to blend the air and fuel or to equip (an engine) with a carburetor for that purpose.
