Carburetor \Car"bu*ret`or\, Carburettor \Car"bu*ret`tor\, n.
   One that carburets; specif., an apparatus in which air or gas
   is carbureted, as by passing it through a light petroleum
   oil. The carburetor for a gasoline engine is usually either a
   {surface carburetor}, or a {float, float-feed, or spray},
   {carburetor}. In the former air is charged by being passed
   over the surface of gasoline. In the latter a fine spray of
   gasoline is drawn from an atomizing nozzle by a current of
   air induced by the suction of the engine piston, the supply
   of gasoline being regulated by a float which actuates a
   needle valve controlling the outlet of the feed pipe. Alcohol
   and other volatile inflammable liquids may be used instead of
   gasoline.
