Definition of 'surface carburetor'

From: GCIDE

Carburetor \Car"bu*ret`or\, Carburettor \Car"bu*ret`tor\, n.
1. (Chem.) 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. [Written also carburettor.] [1913 Webster]
2. 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.]
