noun (Automotive engineering: Vehicle components, Engine, transmission, and exhaust) Carburetion is the process of fuel becoming vapor and mixing with a stream of air in a carburetor. ⇒ The carburetion system has been refined to help the engine breathe better. ⇒ The purpose of carburetion is to provide a combustible mixture of fuel and air in the required quantity and quality for efficient operation of the engine under all conditions. ⇒ The primary advantage of fuel injection over traditional carburetion is the ability of a fuel-injected engine to be unaffected by conditions such as temperature, humidity, and altitude, which affect traditional carburetion.
