The carburetor, carburettor, or carburetter also called carb (in North America) or carbie (chiefly in Australia) for short, is a device that mixes air and fuel for an internal combustion engine. It was invented by Hungarian scientists Donát Bánki and János Csonka in 1893. Carburetors are still found in small engines and in older or specialized automobiles such as those designed for stock car racing. However, fuel injection, first introduced in the late 1950s and first successfully commercialized in the early 1970s, is now the preferred method of automotive fuel delivery. The majority of motorcycles still are carburated due to lower weight and cost, but as of 2005 many new models are now being introduced with fuel injection.
