Definition: A carburetter is a device used for heating and lubricating engines, especially in automobiles. It functions by heating the fuel mixture in the engine's cylinder or combustion chamber to improve fuel efficiency and reduce emissions. Carburettors are typically made of metal or plastic and are connected to the spark plugs that ignite the fuel during the combustion process. They also serve as a means for regulating the temperature of the fuel, which is critical for maintaining the proper combustion and reducing engine damage.
