Carburetter, also known as a carburetor, is a device that mixes fuel and air for combustion in an internal combustion engine. It is an essential component of the engine system. However, there are other synonyms of carburetter, such as a mixer, vaporizer, or atomizer. These words refer to a device that mixes fuel and air in varying amounts for a combustion engine. Carburetters are extensively used in vehicles with gasoline engines, but with the advancements in technology, many modern vehicles are now equipped with fuel injection systems instead of carburetors. Despite the changing trends in the automotive industry, carburetors remain an important component of older vehicles.
