A
carburetor is a device that
mixes air and
fuel
in an
optimal air-
fuel ratio for combustion in internal combustion
engines. In the
United Kingdom
and
North America, the term is commonly abbreviated as the
carb, and in
Australia, it is abbreviated as
carby. To carburetor or carburate means to mix air and fuel, or to equip a vehicle with a carburetor for this purpose.
In the automobile and, to a lesser extent, aviation sectors, fuel injection technology has largely replaced
carburetors. Carburetors are still widely used in lawnmowers, rototillers, and other
small engines.
Samuel Morey invented the first carburetor in 1826. Siegfried Marcus
was the first to design a carburetor for use in a petroleum engine, with his invention for a system that mixes fuel and air on
July 6, 1872. In 1888, Karl Benz patented a carburetor
as part of his research and development of internal combustion engines and their components. The first carburetors were surface carburetors, which blend air and fuel by flowing over the surface of gasoline.
Wilhelm Maybach &
Gottlieb Daimler created a float carburetor using the
atomizer nozzle in
1885. The
Daimler-
Maybach carburetor was widely imitated, resulting in patent disputes. The Daimler company's claim of precedence was dismissed in favor of
Edward Butler's 1884 spraying carburetor, which he employed on his
Petrol Cycle. In
1893,
Hungarian
engineers
János Csonka and
Donát Bánki patented a stationary
engine carburetor.
