A carburetor (American English) or carburettor (British English; see spelling differences) is a device that blends air and fuel for an internal combustion engine in the proper ratio for combustion. It is sometimes colloquially shortened to carb in the UK and 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. A buret or burette is equipment for measuring liquids accurately.
