CIDE DICTIONARY

carburettor, n. 

•  An apparatus in which coal gas, hydrogen, or air is passed through or over a volatile hydrocarbon, in order to confer or increase illuminating power.  [1913 Webster]
•  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 alternatively a float carburetor (called also float-feed carburetor, 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.  [Webster 1913 Suppl.]
