Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, but carburetors are still used by some small engines (e.g. lawnmowers, generators, and concrete mixers) and motorcycles. In addition, they are still widely used on piston-engine–driven aircraft.

The carburetor, also called carburetor, is a device that operates by the gasoline internal combustion engine for regulation and mixing air and fuel to provide to the engine.
Getting the fuel-air mixture just right is the job of a clever mechanical gadget called a carburetor: a tube that allows air and fuel into the engine through valves, mixing them together in different amounts to suit a wide range of different driving conditions.
A carburetor takes the liquid gasoline from the gas tank and mixes it with air, which then travels to the combustion chamber, where the mixture is ignited by the spark plug.

Carburetors are used to mix fuel and air together before sending the mix into the engine cylinders for ignition, powering the vehicle. The carburetor sits atop the engine block beneath the air filter, and operates using a combination of vacuum power and cable control.
The function of a carburetor is to mix air and fuel in the proper ratio for combustion. This air-fuel mixture is essential for generating the power that drives the vehicle.
