CARBURETOR

Optionally spelled carburetter or carburettor. A device that vaporizes fuel and mixes it with air in proper quantities and proportions to suit the varying needs of the engine. A filter screens the air which is drawn into the carburetor. Here the gasoline mixes with the air and this fuel vapor enters the combustion chamber through the intake valve where it is compressed and burned.
