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.

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.

Device which mixes fuel and air and controls the amount of mixture entering the engine. The carburetor provides the engine with the proper mixture of fuel and air.

A mechanical device found on the intake side of the engine which mixes fuel and air to create the volatile mixture that gets ignited in the engine.
