A carburetor is a device that mixes air and fuel in an internal combustion engine. It is responsible for delivering the correct air-fuel ratio to the engine for efficient combustion. Carburetors work by drawing fuel from a fuel tank and atomizing it into a fine spray. This spray then mixes with air, creating a combustible mixture that is drawn into the engine cylinders. The amount of fuel and air entering the engine is controlled by a throttle valve, which is operated by the driver's accelerator pedal.

There are several types of carburetors, including downdraft, updraft, and sidedraft. Each type has a different arrangement of components, but they all perform the same basic function. The main components of a carburetor include a float bowl, a jet, a venturi, and a throttle valve. The float bowl maintains a constant level of fuel, while the jet controls the amount of fuel that flows into the engine. The venturi is a constricted passage that creates a low-pressure area, drawing fuel into the airstream. The throttle valve regulates the amount of air entering the engine, thereby controlling engine speed and power.

Carburetors were the primary fuel delivery system for gasoline engines for many decades. However, they have largely been replaced by fuel injection systems in modern vehicles. Fuel injection systems offer more precise control over the air-fuel mixture, leading to improved fuel efficiency, lower emissions, and better engine performance. Carburetors are still found in some older vehicles, as well as in smaller engines such as those in motorcycles, lawnmowers, and some aircraft.
